C. Measurements and Approximations of Total Radioactivity

1. Gaseous Effluents

Fission and Activation Gases

The gaseous radioactivity released from the plant vent is monitored by a pairof off-line monitors equipped with beta scintillator detectors. The monitorreadings are correlated to isotopic concentration based on. laboratory isotopicanalysis of grab samples using a germanium detector.

When plant vent measurements, as indicated by the process monitors, arebelow the lower limitof detection, grab samples results are used to quantifyreleases. The individual batch release data are used to quantify theradioactivity discharged from the gas decay tanks and containment.

A noble gas grab sample is obtained and analyzed at least weekly. Theisotopic mixture is assumed to remain constant between grab sampleanalyses.

Containment purges, gas decay tank releases, and air ejector discharges arereleased via the plant vent.

The gaseous radioactivity released from the steam generator blowdown tankvent is measured by analyzing liquid or steam condensate grab samples witha germanium detector. A factor R, a ratio of unit masses between waterflashing to steam and water entering the tank, is used to calculate the activity.The isotopic concentrations are assumed to remain constant between grabsamples.

Other potential pathways for releasing gaseous radioactivity are periodically. monitored by collecting grab samples and analyzing these samples with a

germanium detector system.

b. lodines

Radioiodines released from the plant vent are monitored by continuoussample collection on silver zeolite cartridges. The cartridges are changed atleast weekly and analyzed with a germanium detector. The radioiodinereleases are averaged over the period of cartridge sample collection.

Other potential pathways for releasing radioiodines are periodically monitoredby collecting samples using charcoal cartridges and analyzing with agermanium detector.

EnclosurePG8 E Letter DCL 99-055

Radioactive materials in particulate form released from the plant vent aremonitored by continuous sample collection on particulate filters. The filtersare changed at least weekly and analyzed with a germanium detector. Theparticulate radioactivity is averaged over the period of particulate filtersamplecollection. Each filter is analyzed for alpha emitters using an internalproportional counter. Plant vent particulate filters collected during a quarterare used for the composite analysis for strontium-89 and -90 which is countedon an internal proportional counter after chemical separation.

Other potential pathways for releasing radioactive particulate are periodicallymonitored by collecting samples using particulate filters and analyzing thesefilters with a germanium detector.

Tritium

Tritium released from the plant vent is monitored by passing a measured'olumeof plant vent sample through a water column and determining the

tritium increase in the water. An aliquot of the water is counted in a liquidscintillation spectrometer. The minimum'routine sample frequency for tritiumis weekly. The tritium concentration is assumed to remain constant betweensamples.

Estimations of Overall Error

Sources of error considered for batch release are: (1) calibration source; (2)calibration counting; (3) sampling; (4) sample counting; and (5) gas decaytank pressure gauge / containment exhaust fan flow rate.

Sources of error for continuous release are: (1) calibration source; (2)calibration counting; (3) sampling; (4) sample counting; (5) process monitor(RE-14) reading (fission gases only); and (6) plant vent exhaust fan flow rate.

2. Liquid Effluents

Batch Releases

Each tank of liquid radwaste is analyzed for principal gamma emitters using agermanium detector prior to release. A monthly prerelease analysis includesdissolved and entrained gases. Volume proportional monthly and quarterlycomposites are prepared from aliquots of each tank released. The monthlycomposite is analyzed for tritium using a liquid scintillation spectrometer and

gross alpha radioactivity using an internal proportional counter. The quarterlycomposite is analyzed for iron-55 using a liquid scintillation spectrometer andfor strontium-89 and -90 using an internal proportional detector followingchemical separations.

b. Continuous releases

For the continuous liquid releases of the steam generator blowdown tank andturbine building sump oily water separator;-daily-grab samples are collectedand aliquots are proportioned for weekly, monthly, and quarterly composites.

The oily water separator weekly composite is analyzed for principal gammaemitters using a germanium detector. The steam generator blowdown tankweekly composite is analyzed for principal gamma emitters and iodine-131.

The steam generator blowdown tank monthly composite is analyzed for tritiumusing a liquid scintillation spectrometer and for gross alpha using an internalproportional counter.

The steam generator blowdown tank quarterly composite is analyzed for iron-55 using a liquid scintillation spectrometer and for strontium-89 and strontium-90 using an internal proportional counter following chemical separation. Theresults for each of the composites are averaged over the period of thecomposite.

In addition, one grab sample of the steam generator blowdown tank isanalyzed monthly for dissolved and entrained gases using a germaniumdetector. The results of this analysis are assumed to remain constant overthe period of one month.

c. Estimation of Overall Error

Sources of error considered are: (1) calibration source error; (2) calibrationcounting error; (3) sampling error; (4) sample counting error;.and (5) volumeof waste release error.

These sources of error are independent; thus the total error is calculatedaccording to the following formula:

Total error = (a', + a', + a', + ... a',) '"

E. Abnormal Release (Gaseous and Liquid

From December 24, 1998, through December 31, 1998, an unplanned, butmonitored, release of Unit 1 condensate occurred due to a leak on the CondensateDischarge Overboard Valve CND-1-128. During this event, 3.09E-2 curies of tritiumwere released. The percent of effluent concentration limitwas 5.11 E-4 percent ofthat specified in RMCP IDAP CY2.ID1, step 6.1.3.1.

F. Effluent Monitoring Instrumentation

On March 25, 1998, RE-18 (Liquid Effluent Monitor) alarmed. The alarm was mostlikely due to activated corrosion product accumulation in the piping dead legs sharedby the liquid radwaste system discharge and process pathways. The activatedcorrosion products were transported to the RE-18 monitor during the beginning ofdischarge causing a RCV-18 trip which terminated the release. The residue in theline was then flushed back to the liquid radwaste system after a sample was obtainedand analyzed. The percent of effluent concentration limitwas 1.65 E+0 percent ofthat specified in RMCP IDAP CY2.ID1, step 6.1.3.1.

II. Major Changes to Liquid, Gaseous and Solid Radwaste Treatment System

There were no major changes to liquid, gaseous, and solid radwaste treatment systemsduring the report period.

XI. Radiation Dose Due to Gaseous and Liquid Effluents

Radiation Doses

A. Radiation doses from radioactive liquid effluents

The radiation dose contributions due to releases of radioactive liquid effluents to thetotal body and each individual organ for the maximum exposed adult have beencalculated in accordance with the methodology in the ODCP;-Dose contributionslisted in Table 7 show conformance to RECP 6.1.4.1.

B. Radiation doses from radioactive gaseous effluents

The radiation dose contributions due to radioactive gaseous effluents at the siteboundary for the land sectors have been calculated in accordance with thecalculation meth'odology in the ODCP. Each unit's dose contribution has beencalculated separately. The latest five year historical average meteorologyconditions were used in these calculations. In addition to the site boundary doses,the dose to an individual (critical receptor) due to radioiodines, tritium, andparticulates released in gaseous effluents with half-lives greater than,8 days isdetermined in accordance with the methodology in the ODCP based on themethodology described in NUREG 0133. Dose contributions listed in Table 8,which represents the maximum dose for age groups, organs, and geographiclocations for the report period, show conformance to RECP 6.1.6.1, 6.1.7.1, and6.1.8.1.

C. Radiation Doses from Direct Radiation (Line-of-Sight Plus Sky-Shine)-Closest Site Boundary (800 m)

For the report period, the radiation dose is evaluated to be 8.72E-2 mrem due tothe presence of radioactive waste containers outside of plant buildings and thestorage of contaminated tools and equipment inside plant buildings.

D. Radiation Doses from Chemistry Laboratory Radioactive Gaseous Effluents-Closest Site Boundary (800m)

The radiation doses due to chemistry laboratory radioactive gaseous effluents forthe report period is evaluated to be 2.31E-6 mrem.

E. Radiation Doses from Post-accident Sampling System Radioactive GaseousEffluents - Closest Site Boundary (800m)

The radiation doses due to post-accident sampling system radioactive gaseouseffluents for the report period is evaluated to be 2.29E-6 mrem.

EnclosurePG8E Letter DCL 99-055

F. 40CFR190 Considerations

The release of radioactivity in liquid and gaseous effluents during 1998 resulted indoses that are small percentages of the TS limits as shown in Tables 9 and 10.This, coupled with the fact that there are no other uranium fuel cycle sources withineight kilometers of the DCPP, shows conformance to 40CFR190.

G. Radiation Doses from Radioactive Liquid And Gaseous Effluents to Membersof the Public Due To Their Activities Inside The Site Boundary..

1. Liquid Effluents

The radiation dose to members of the public within the site boundary due to therelease of radioactive liquid effluents is negligible because the discharge piping forliquid radwaste is mostly imbedded in concrete, located in remote or inaccessibleareas, or is underground. In addition, the quantity of radioactivity released was verylow during 1998.

2. Gaseous Effluents

The radiation dose to members of the public within the site boundary due to therelease of radioactive gaseous effluents are listed in Table 11 for the year of 1998.

PROGRAM OVERVIEW

It is the policy of Nuclear Power Generation (NPG) that the release of radioactive materials to theenvironment be in compliance with Federal regulations and be "As Low As ReasonablyAchievable" (ALARA). The overall objectives are to protect the health and safety of the publicfrom undue radiation exposure and to minimize the amount of radioactive effluents resulting fromthe operation of the Diablo Canyon Power Plant.

This PD defines the overall policies and general requirements related to the RadiologicalMonitoring and Controls Program (RMCP). This includes the Radiological EnvironmentalMonitoring Program, and the Radioactive Effluent Controls Program.

2. APPLICABILITY

This PD is applicable to all persons involved in radioactive effluent control, monitoring, and

management activities. This includes all NPG personnel, personnel matrixed to NPG from otherPG&E organizations, personnel in other PG&E organizations that are engaged in activities in

support of NPG, and contractor personnel that are working under NPG supervision.

DEFINITIONS

3.1 ALARA(acronym for "as low as reasonably achievable" ) - A term that means making

every reasonable effort to maintain exposures to radiation as far below the dose limitsof 10 CFR 20 as is practical consistent with the purpose for which the licensed activityis undertaken,'aking into account the state of technology, the economics ofimprovements in relation to state of technology, the economics of improvements inrelation to benefits to the public health and safety, and in relation to utilization ofnuclear energy and licensed materials in the public interest.

It should be recognized that the LLD is defined as an ~ariori (before the fact) limit representingthe capability of a measurement system and not as an ~aosterior (atter the fact) limit for a

particular measurement.

A composite sample is one in which the quantity of liquid sampled is proportional to the quantityof liquid waste discharged and in which the method of sampling employed results in a specimenwhich is representative of the liquids released.

To be representative of the quantities and concentrations of radioactive materials in liquideffluents, samples shall be composited in proportion to the rate of flow of the effluent stream.Prior to analyses, all samples taken for the composite shall be thoroughly mixed in order for thecomposite sample to be representative of the effluent release.

A batch release is the discharge of liquid wastes of a discrete volume. Prior to sampling foranalyses, each batch shall be isolated, and then thoroughly mixed, by a method described in theODCP, to assure representative sampling.

Radioactive Gaseous Effluent Monitorin Instrumentation

The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable,the releases of radioactive materials in gaseous effluents during actual or potential releases ofgaseous effluents. The Alarm/Trip Setpoints for these instruments shall be calculated and adjustedin accordance with the methodology and parameters in the ODCP to ensure that the alarm/trip willoccur prior to exceeding the limits of NUREG 0133. The OPERABILITYand use of thisinstrumentation is consistent with the requirements of General Design Criteria 60, 63, and 64 ofAppendix A to 10 CFR Part 50. The sensitivity of any noble gas activity monitors used to showcompliance with the gaseous effluent release requirements of Regulatory Commitment 6.1.7.1shall be such that concentrations as low as 1 x 10~ pCi/ml are measurable.

Li uid Effluents - Concentration

This Regulatory Commitment is provided to ensure that the concentration of radioactive materialsreleased in liquid waste effluents to UNRESTRICTED AREAS willbe less than the concentrationlevels specified in 10 CFR Part 20, Appendix B, Table 2, Column 2. This limitation providesadditional assurance that the levels of radioactive materials in bodies of water inUNRESTRICTED AREAS willresult in exposures within: (1) the Section II.Adesign objectivesof Appendix I, 10 CFR Part 50, to a MEMBER OF THE PUBLIC, and (2) the limits of10 CFR 20.1301(e) to the population. The concentration limit for dissolved or entrained noblegases is based upon the assumption that Xe-135 is the controlling radioisotope and its EffluentConcentration Limit (ECL) in air (submersion) was converted to an equivalent concentration inwater using the methods described in International Commission on Radiological Protection (ICRP)Publication 2.

This Regulatory Commitment applies to the release of radioactive materials in liquid effluentsfrom all units at the site.

The required detection capabilities for radioactive materials in liquid waste samples are tabulatedin terms of the lower limits of detection (LLDs). Detailed discussion of the LLD, and otherdetection limits can be found in Currie, L.A., "Lower Limitof Detection: Definition andElaboration of a Proposed Position for Radiological Effluent and Environmental Measurements,"NUREG/CR-4007 (September 1984), and in the HASL Procedures Manual, HASL-300 (revisedannually).

APPENDIX 6.1 Continued

This Regulatory Commitment is provided to ensure that the dose at any time at and beyond theSITE BOUNDARYfrom gaseous effluents from all units on the site willbe within the annual dose

limits of NUREG 0133 to UNRESTRICTED AREAS. The annual dose limits are the doses to beassociated with the concentrations of 10 CFR Part 20, Appendix'B, Table 2, Column 1. Theselimits provide reasonable assurance that radioactive material discharged in gaseous effluents willnot result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA,either within or outside the SITE BOUNDARY, to average concentrations exceeding the limits tobe specified in Appendix B, Table 2 of 10 CFR Part 20 (10 CFR Part 20.1302(c)). ForMEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, theoccupancy of that MEMBER OF THE PUBLIC willusually be sufficiently low to compensate forany increase in the atmospheric diffusion factor above that for the SITE BOUNDARY. Examplesof calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors,shall be given in the ODCP. The specified release rate limits of NUREG 0133 restrict, presently,the corresponding gamma and beta dose rates above background to a MEMBER OF THEPUBLIC at or beyond the SITE BOUNDARYto less than or equal to 500 mrems/year to thewhole body or to less than or equal to 3000 mrems/year to the skin. These release rate limits alsorestrict, at all times, the corresponding thyroid dose rate above background to a child via theinhalation pathway to less than or equal to 1500 mrems/year.

6.1.9 Gaseous Radwaste Treatment S stem

The OPERABILITYof the GASEOUS RADWASTE SYSTEM and the VENTILATIONEXHAUST TREATMENTSYSTEM ensures that the systems willbe available for use whenevergaseous effluents require treatment prior to release to the environment. The requirement that theappropriate portions of these systems be used, when specified, provides reasonable assurance thatthe releases of radioactive materials in gaseous effluents willbe kept "as low as is reasonablyachievable." This specification implements the requirements of 10 CFR 50.36a, General DesignCriterion 60 of Appendix A to 10 CFR Part 50 and the design objectives given in Section II.D ofAppendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions ofthe systems were specified as a suitable fraction of the dose design objectives set forth in SectionsII.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents.

This Regulatory Commitment applies to the release of radioactive materials in gaseous effluentsfrom each unit at the site. For units with shared Radwaste Treatment Systems, the gaseouseffluents from the shared system are proportioned among the units sharing that system.

6.1 ~ 10 Total Dose

This Regulatory Commitment is provided to meet the dose limitations of 40 CFR Part 190 thathave been incorporated into 10 CFR Part 20 by 46 FR 18525. The specification requires thepreparation and submittal of a Special Report whenever the calculated doses due to releases ofradioactivity and to radiation from uranium fuel cycle sources exceed 25 mrems to the whole bodyor any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems. Forsites containing up to four reactors, it is highly unlikely that the resultant dose to a MEMBER OFTHE PUBLIC willexceed the dose limits of 40 CFR Part 190 ifthe individual reactors remainwithin twice the dose design objectives of Appendix I, and ifdirect radiation doses from the unitsand from outside storage tanks are kept small. The Special Report willdescribe a course of actionthat should result in the limitation of the annual dose to a MEMBER OF THE PUBLIC to withinthe 40 CFR Part 190 limits. For the purposes of the Special Report, it may be assumed that thedose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources isnegligible, with the exception that dose contribution from other nuclear fuel cycle facilities at thesame site or within a radius of 8 km must be considered. Ifthe dose to any MEMBER OF THEPUBLIC is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a

request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190have not already been corrected), in accordance with the provisions of 40 CFR 190.11 and10 CFR 20.2203(a), is considered to be a timely request and fulfillsthe requirements of40 CFR Part 190 until NRC staff action is completed. The variance only relates to the limits of40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of10 CFR Part 20, as addressed in Regulatory Commitment 6.1.3.1 and 6.1.6.1. An individual isnot considered a MEMBER OF THE PUBLIC during any period in which he/she is engaged incarrying out any operation that is part of the nuclear fuel cycle.

6.1.3 Liquid Effluent Radiation Monitor Set Point Methodology

Introduction

The DCPP radiological effluent controls program requires that theliquid effluent monitors be operable with their alarm/trip set points set

to ensure that the effluent concentration limits of 10 CFR 20 are notexceeded.

The alarm/trip set point for the liquid effluent radiation monitors is

derived from the concentration limitset forth in Appendix B, Table 2,Column 2 of 10 CFR 20.1001-2404.

The alarm/trip set points are applied at the unrestricted area boundary.The set points take into account appropriate factors for dilution,dispersion, or decay of radioactive materials that may occur betweenthe point of discharge and the unrestricted area boundary.

b. Allocation and Safety Factors

The limits of RCMP 6.1.3.1 are site limits which require that the set

point methodology must ensure simultaneous releases do not exceed the

liquid effluent concentration limits of 10 CFR 20 in the unrestrictedarea. The DCPP High Alarm Set Point (HASP) methodology makesuse of an Allocation Factor (AF) to limit'he effluent concentrationsfrom simultaneous liquid discharges. The Allocation Factors can be

adjusted based upon, operational requirements with the restriction thatthe sum of the Allocation Factors must be less than or equal to 1.

Typical Allocation Factors are shown Table 6. 1.

0.900.040.040.01

An additional level of conservatism in the HASP methodology is

implemented by the use of a Safety Factor (SF). The Safety Factor is

defined as 0.9 and provides for a High Alarm Set Point at 90% of the10 CFR 20 concentration limits.

Tritium Correction Factor „

As result of an aggressive liquid radwaste treatment program, the liquideffluents at DCPP typically contain very low levels, of gamma emitters.In order to reduce the over all volume of liquid waste discharged,DCPP also recycles waste water. This recycling results in highertritium concentration in liquid effluents when compared with the lowgamma emitter concentrations. As a result, standard HASPmethodology results in very low set points. In some cases thecalculated set points are barely above the monitor background.

The liquid HASP methodology used by DCPP uses a TritiumCorrection Factor (TCF) which assumes a constant, but conservativetritium concentration in the liquid effluent. This results in an

operationally reasonable set point while ensuring that the liquid effluentconcentrations released to the unrestricted areas do not exceed the limitsof 10 CFR 20.

d. Liquid Effluent Radiation Monitor Set Point Calculations

The High Alarm Set Point (HASP) are calculated to ensure that theliquid effluent concentration limits of 10 CFR 20 are not exceeded.The set points represent the maximum operational set point. The actualset point used by operations willbe equal to or less than the actualvalue as determined by the HASP methodology described in thissection.

1. Set Point Methodology for RE-3 HASP: Oily Water Separator

Under normal conditions, the Oily Water Separator stream does

not contain any radioactive material. Only in the event that thereis primary to secondary leakage does this become a potentialliquid effluent discharge point. In order to insure that nounplanned or unmonitored releases take place by way of the OilyWater Separator, RE-3 serves to monitor the discharge even whenno activity has been identified in the effluent. When no significantprimary to secondary leakage is taking place or when no activityhas been identified in the Oily Water Separator, the High AlarmSet Point for RE-3 is calculated as shown in Equation 8.

6.2 Gaseous Effluents

The only significant path for gaseous radioactive releases to the environment duringnormal operations is via the plant vent. This source is used for calculating dose rates

and real-time doses to the unrestricted area due to noble gases, vaporous radioiodinesand airborne radio-particulates. The plant vent also has redundant monitoring for these

types of gaseous releases.

Other paths such as the steam generator blowdown tank vent, the chemistry lab fumehood, the main condenser Nash vacuum pump discharge, hot machine shop vent, etc.,'are considered miscellaneous release sources. These miscellaneous release sources arenot continuously monitored but can have dose rates and dose calculated for their path tothe unrestricted area.

6.2.1 Meteorological Methodology

The equations for determining gaseous effluent concentration limits, highalarm setpoints, dose rates, and critical receptor doses make use of thehistorical average atmospheric conditions in accordance with methodologiesof Regulatory Guides 1.109 and 1.111 and NUREGs 0133 and 0472. Thehistorical average dispersion (X/Q) and deposition (D/Q) values are derivedfrom the methodology of Regulatory Guide 1.111 as implemented byNUREG 2019 (computer code XOQDOQ). The DCPP dispersion anddeposition values are based on the latest five years of meteorological data andare updated when the value of X/Q or D/Q changes by more than ten percent.The present values are listed in Table 10.2.

Long-term releases are characterized as those that are generally continuousand stable in release rate, such as normal ventilation systems effluents.Doses due to long-term releases are modeled using historical annual averagedispersion and deposition values in accordance with the guidance ofRegulatory Guide 1.109, Regulatory Guide 1.111, NUREG 0133 andNUREG 0472.

Short-term releases are defined as those which occur for a total of 500 hoursor less in a calendar year but not more than 150 hours in any quarter. Inaccordance with NUREG 0133 and based upon an operational history thathas demonstrated short term gaseous releases can be characterized as randomin both time of day and duration, historical average atmospheric dispersionand deposition values are used to model doses due to short-term releases.

6.2.2 Gas Effluent Concentration Limits

a. Philosophy of Concentration Limits .

The radiological effluent controls restrict at all times the dose rate dueto radioactive materials released in gaseous effluents from the site toareas at or beyond the site boundary for noble gases to less than orequal to 500 mrem/yr to the total body and 3000 mrem/yr to the skin.For iodine-131, iodine-133, tritium and for all radionuclides inparticulate form with half-lives greater than 8 days, the dose rate is

limited to less than or equal to 1500 mrem/yr to any organ.

These dose rate limits act to restrict at all times the instantaneousconcentrations of radionuclides in gaseous effluents at the siteboundary.

l. Allocation and Safety Factors

The limits set forth by RCMP 6.1.6.1 are site limits which requirethat the set point methodology must ensure simultaneous releasesdo not exceed the off-site dose rate limits set forth by RCMP6.1.6.1(a) and 6.1.6.1(b). The DCPP High Alarm Set Pointmethodology makes use of an Allocation Factor (AF) to limit thenoble gas effluent dose rate from simultaneous atmosphericreleases.

The Allocation Factors can be adjusted based upon operationalrequirements with the following restrictions:

The sum of the Allocation Factors for RE-14, the SGBDtank vents, and miscellaneous release points from both unitsmust be less than or equal to 1.

The Allocation Factors for RE-22 (Waste Gas Decay Tanks)and RE-44 (Containment Purge) can also be adjusted based

upon operational requirements with restriction that the sum'of the Allocation Factors for RE-22 and RE-44 must be less

than or equal to the Allocation Factor for RE-14.

The Allocation Factors for RE-24 (Plant Vent IodineMonitor) and RE-28 (Plant Vent Particulate Monitor) are set

equal to the Allocation Factor for RE-14.

6.2.5 Dose To Critical Receptor Due To Radioiodines, Tritium and ParticulatesReleased in Gaseous Effluents

a. Calculation Methodology

The dose to an individual (critical receptor) due to radioiodines, tritiumand particulates released in gaseous effluents with half-lives greater than8 days is determined based upon the methodology described inNUREG 0133. This methodology makes use of the maximumindividual concept described in Regulatory Guide 1.109. Themaximum individual is characterized as maximum with regard to foodconsumption, occupancy, and other usage parameters. This concepttherefore models those individuals within the local population withhabits representing reasonable deviations from the average. In allphysiological and metabolic respects, the maximum individual isassumed to have those characteristics that represent the average for the

age group of interest.

The concept of critical receptor is introduced as a further refinement ofthe maximum individual. The critical receptor is defined as thatindividual that receives the largest dose based upon the combination ofdose pathways that have been shown to actually exist. The criticalreceptor concept is applied at that location where the combination ofdispersion'(X/Q), deposition (D/Q), existing pathways, occupancy time,receptor age group, and effluent source term indicates the maximumpotential exposure. The inhalation and ground plane exposurepathways are considered to exist at all locations. The grass-cow-milk,grass-cow-meat, and vegetation pathways are considered based on theiractual existence in the vicinityof the plant.

The dose pathways that have been shown to actually exist at DCPP arethe ground plane, inhalation and the vegetation pathways. These dose

pathways are reviewed yearly and updated based upon the annual landuse census survey in order to insure that actual exposure to anindividual willnot be substantially underestimated.

The locations of the pathways and descriptions are listed in Table 10.2.

For purposes of calculating the dose required by the radiologicaleffluent controls, more realistic assumptions concerning the liquid and

gaseous effluent dose pathways willbe used, based upon the mostrecent land use census data as well as the latest environmentalmonitoring information.

These assumptions may include, but not be limited to: more realisticliquid dilution factors; location and age of actual individuals, sitespecific food pathway parameters, and documentation of true foodconsumption.

6.4 On-Site Dose to Members of the Public

Members of the public are occasionally granted access within the site boundary, butonly in the owner controlled area up to the protected area boundary. The mostcommon public access activities are: tours to the simulator (training building) or BioLab, policemen using the shooting range (most frequent activity), cattle drives throughto adjacent properties, and visits of American Indians to on-site burial grounds (closestto the plant).

Exposure to members of the public due to liquid releases while on-site is highly unlikelyand therefore not addressed. Exposure due to gaseous releases and direct radiation arecredible and therefore are considered.

The dose to members of the public during on-site activities willbe primarily determined

by the duration of the on-site visitation time and by the closest proximity to the plant.

For gaseous releases the doses are calculated using Equations 44, 45 and 33. The R s

in Equation 33 consider only the inhalation and ground plane pathway and exclude theinfant age group.

The X/Q and D/Q values are modified using logarithmic extrapolation from the siteboundary to the on-site location of interest as shown in Equations 46 and 47.

log [X/Q ]

log [X/Q ]> >—log [X/Q ]ttoe [log (dist on - site.) —iog (dist S tt)]..

log [D//Q]» —log [D/Q],"'log (dist on - site) —iog (dt'st g tt)]..log (dist.S./3.) —log (dist. loc.)

+ log [D/Q]

(47)

Based upon Regulatory Guide 1.111, these equations can be expected to providereasonable dispersion and deposition estimates for distances as close as 200 meters.

Determination of direct radiation dose from the reactor units and from outside storagetanks may be made by direct survey measurements, derived from environmental TLDdata, or calculated by shielding code.

A distance of 200 meters from the plant (both units) equidistant from the plant vent is

arbitrarily selected as the closest perimeter for which on-site doses willbe calculated.

SAMPLING PROGRAM FOR SOLIDIFICATION

Vendors, utilized by DCPP for radioactive waste solidification, are requiredto include in their approved procedures, requirements to sample at least everytenth batch of the same waste type to ensure solidification and to provideactions to be taken ifa sample fails to verify solidification. After a test

specimen failure, initial test specimens from three consecutive batches of thatwaste type must demonstrate solidification before testing requirements ofevery tenth batch can be resumed. Verification of such sampling is to beaccomplished by completing Form 69-10350, "Processing Control Program(PCP) Verification." (See Attachment 7.1.) These forms willbe maintainedin the Radiation Protection Section and the Records Management System(RMS).

handling waste for the determination of process parameters prior to the actualfull scale solidification. These procedures contain the description of thelaboratory mixing methods used for these samples.

SOLIDIFICATIONPROCESS

Qualified vendors used by DCPP for radioactive waste solidification are

required to provide the Process Control Program and written procedures.These procedures and changes thereto must be reviewed by the PSRC and

approved by the Plant Manager prior to use. Further, the vendors arerequired to have a topical report, as referenced, on the waste forms whichwillbe solidified at DCPP. This topical report should demonstratecompliance with the NRC requirements for waste form. These documentsshould include:

a. Description of the solidification process.

b. Type of solidification used.

c. Process control parameters.

d. Parameter boundary conditions.

e. Proper waste form properties.

Specific instructions to ensure the systems are operated withinestablished process parameters.

SAMPLING PROGRAM FOR SOLIDIFICATION

Vendors, utilized by DCPP for radioactive waste solidification, are requiredto include in their approved procedures, requirements to sample at least everytenth batch of the same waste type to ensure solidification and to provideactions to be taken ifa sample fails to verify solidification. After a testspecimen failure, initial test specimens from three consecutive batches of thatwaste type must demonstrate solidification before testing requirements ofevery tenth batch can be resumed. Verification of such sampling is to beaccomplished by completing Form 69-10350, "Processing Control Program(PCP) Verification." (See Attachment 7.1.) These forms willbe maintainedin the Radiation Protection Section and the Records Management System(RMS). These procedures and changes thereto must be reviewed by thePSRC and approved by the Plant Manager prior to use.

1998 Land Use Census

DCPP Radiation Protection personnel conducted a land use census in the vicinity of

DCPP for 1998. The land use census is based on Nuclear Regulatory Commission

(NRC), Regulatory Guide 4.8, "Environmental Technical Specifications for Nuclear

Power Plants", and required by DCPP Program Directive CY2, "Radiological

Monitoring and Controls Program." The census is conducted at least once per year

during the growing season for the Diablo Canyon environs.

The land use census identifies the nearest milk animal and garden greater

than 50 square meters (500 square feet), producing broadleaf vegetation, in each ofthe landward meteorological sectors within a distance of 8 kilometers (5 miles) of the

plant. DCPP IDAP RP1.ID11 "Environmental Radiological Monitoring Program",

requires that the nearest residence be identified in each of the landward sectors

within a distance of 5miles.'he

land use census was performed by directly contacting individual landowners or

tenants, or by aerial surveys. The landowners or tenants were contacted between

July 7 and August 31, 1998. The aerial survey was done on August 5, 1998.

The census identified one household garden in the east sector at 4.5 miles, greaterthan 50 square meters (500 square feet) that produces broadleaf vegetation. No

milk animals were identified within the first 5 miles in any sector. Much of the area

surrounding the plant site is used for cattle grazing. Goats were used for weed

abatement for approximately 7 months within the area surrounding the plant site. Afarm is located on the coastal plateau in the east southeast (ESE) sector, along the

site access road. The farm starts at approximately 3.3 miles and extends to 4.5

miles from the plant, but produces only legumes and cereal grass (grains).

A total of 13 residences were identified within the 5-mile radius of the plant that were

confirmed to be, or appeared to be, occupied during 1998. The nearest residence is

1.2 miles north-west (NW) of the plant. Table 1 summarizes the results of the land

use census and Figure 1 shows the locations of the farm and residences in the

vicinity of DCPP.
