Background

In CCNPP Unit 3 COLA Rev 8, to address the requirement of RG 1.189, UniStar had classified portions of the Fire Protection System (FPS) as Seismic Cat II-SSE.

To address RAI 253, UniStar removed the Cat II-SSE and changed it to be consistent with DC FSAR classification.

This change raised the question of how the design would meet the requirement of RG 1.189

Objective of the presentation

Explain the seismic classification method and design criteria that is used to meet the requirement of RG 1.189

Go through the RAI 378 questions, describe the basis for our response and solicit NRC feedback

RAI 378 QUESTION 03.07.02-75 Item E - Requirements for Fire Water Storage Tanks (FWSTs)

RAI 378 QUESTION 03.07.02-75

• In Enclosure 2, page 15 of 38, it states that the FPB and the FWSTs are designated as SC II. For the FPB and FWSTs this statement does not agree with the seismic classification provided in Table 3.2-1. The applicant is requested to resolve this discrepancy throughout the CCNPP FSAR so it is clear as to what seismic classification the FPB and FWSTs belong. - FPB and FWSTs are classified as Conventional Seismic structures.

The change (from the RAI 253 response) will be made in response to RAI 378 and the FSAR markup will be provided.

Item F - CLASSIFICATION

16

RAI 378 QUESTION 03.07.02-75

• The applicant is requested to justify why shear wave velocity information is not required for the FPB which, according to page 30 of 38, is required to remain functional during and after an SSE. The applicant is also requested to address why the ITAAC requirements of the FPB are also not applicable to the FWSTs.

- Engineered fill in the area of the FPB and FWSTs will be placed with

same materials and specifications as for Category I structures. - UniStar has provided a response to RAI 344, which indicates that

the shear wave velocity and compaction ITAACs used for Category I structures will also be required for the FPB and FWSTs.

FIRE PROTECTION SYSTEM CLASSIFICATION AGENDA

Fire Protection System System Classification and Performance Requirements


18

RAI 378, QUESTION 03.07.02-75 Items A & N – FPS Seismic Classification

A. In Enclosure 2, page 14 of 38, it states that Section 3.2.1 categorizes Fire Protection SSC into two categories:

1) SSC that must remain functional during and after an SSE; and

2) SSC that must remain intact after an SSE without deleterious interaction with any Seismic Category I SSC.

In the revised markup of Section 3.2.1 the staff could not find where the FPS was divided into these two categories. Therefore, the applicant is requested to identify each portion of the CCNPP Unit 3 FPS along with its seismic classification that come under these categories, and include this information in the FSAR.

19

RAI 378, QUESTION 03.07.02-75

N. Provide a table which identifies the seismic classification for each portion of the FPS to include:

- Safety classification - Seismic category - Applicable design codes - Design requirement (no seismic requirement/must remain structurally intact

under an SSE/must maintain its pressure boundary under an SSE/must remain functional during and after an SSE)

UniStar Response: Item A: The site-specific SSCs of the Fire Protection system are seismically classified as shown in the following conceptual flow diagram. Item N: The handout describes the applicable design codes and design requirements for each site-specific SSC.

Items A & N – FPS Seismic Classification

20

RAI 378, QUESTION 03.07.02-75 Item I – FPS Nuclear Island Loop

In Enclosure 2, Table 3.2-1 of the response, a portion of SSCs in component code SGA are designated as SC II and are required to provide safe shutdown equipment protection following an SSE. This is inconsistent with the definition of SC II provided on response page 5 of 38, which only requires that SC II SSCs be designed to withstand SSE seismic loads without incurring a structural failure that permits deleterious interaction with any Seismic Category I SSC. The applicant is requested to resolve this discrepancy.

UniStar Response: COLA FSAR Table 3.2-1 will be updated to describe the site-specific portion of Fire Protection system. The site-specific SSCs providing safe shutdown equipment protection following a safe shutdown earthquake (SSE), which are required to remain functional, will be classified as Conventional Seismic (Note 1). COLA FSAR Section 3.2.1.4, Conventional Seismic will be supplemented to include the additional design criteria.

21

RAI 378, QUESTION 03.07.02-75 Item K – Seismic Input & Method of Seismic Qualification

In Enclosure 2, the ITAAC of Tables 2.4-21, 2.4-24 and 2.4-25 identify seismic qualification reports as Acceptance Criteria for the FPB ventilation system, FW distribution system, and Fire Suppression Systems, respectively. The applicant is requested to identify the source(s) of the seismic input and the method of seismic qualification for the FPB ventilation system, FW distribution system, and Fire Suppression Systems and include this information in Section 3.7.3 of the FSAR. For the FPB ventilation system and other portions of the Fire Protection System supported within the FPB and other structures, the applicant is requested to identify how the seismic input for these SSCs will be developed.

UniStar Response: COLA ITAAC Tables 2.4-21, -24 and -25 will be updated to reflect the correct seismic classification of the associated systems, which is to remain functional following a safe shutdown earthquake (SSE). COLA FSAR Section 3.7.3 will be updated to add the seismic input and the method of seismic qualification for the FPB ventilation system, FW distribution system and fire suppression systems of the FPS in the FPB and other areas. (Refer to Handout for Item O regarding details of the sources of seismic input and method of seismic qualification for the site-specific FPS SSCs)

22

RAI 378, QUESTION 03.07.02-75 Item L – ITAAC: Fire Protection Building Ventilation

In Enclosure 2, the ITAAC of Table 2.4-21 provide Commitment Wording, Inspections, Tests or Analysis, and Acceptance Criteria for portions of the UHS Fire Protection Building System piping and ducting implying that portions of the system are SC I. However, in CCNPP FSAR Table 3.2-1 there is no system identified by this name nor is any part of the Fire Protection System in Table 3.2-1 designated as SC I. The applicant is requested to provide additional details regarding this system including its description, location, design requirements and include this information in the CCNPP FSAR Table 3.2-1 and FSAR Section 3.7. UniStar Response: ITAAC Table 2.4-21 Commitment Wording inadvertently refers to UHS Fire Protection Building. The correct name of the building is Fire Protection Building (FPB). There are no SC I SSCs in the FPB. This ITAAC wording will be corrected in Part 10 of the COLA (ITAAC).

23

RAI 378, QUESTION 03.07.02-75 Item M – ITAAC: FPS Ventilation

In Enclosure 2, ITAAC Table 2.4-21 for item c under the column “ Inspection Test or Analysis” it states in part that type tests, analyses or a combination of tests and analyses will be performed on the piping identified as SC II using analytical assumptions or under conditions which bound the SC I design requirements As this piping has been designated as SC II under the Commitment Wording Column, the applicant is requested to explain this apparent disagreement in the designation of the Fire Water Distribution System seismic classification.

UniStar Response: As described in the response to Item L, ITAAC Table 2.4-21 Item c & d, Commitment Wording, inadvertently refers to UHS Fire Protection Building. The correct name of the building is Fire Protection Building (FPB). There are no SC I SSCs in the FPB. ITAAC Table 2.4-21 Items c & d will be revised for FPS ventilation system ducting classified as Convention Seismic (Note 1) that is required to be functional following an SSE. This ITAAC wording will be corrected in Part 10 of the COLA (ITAAC).

24

RAI 378, QUESTION 03.07.02-75

In Enclosure 2, page 5 of 38, CCNPP Unit 3 FSAR Section 3.2.1.2 markup states that SSCs classified as SC II are designed to withstand SSE seismic loads without incurring a structural failure that permits deleterious interaction with any SC I SSC or that could result in injury to main control room occupants. However, on page 18 of 38, which addresses buried pipe and pipe ducts it states that in accordance with Section 3.2.1, Fire Protection piping to Seismic Category (SC) I structures that is classified as: 1) SC II is designed to maintain its pressure boundary after an SSE event; and 2) is designed to remain functional during and following an SSE event. 1) First, as written it is not clear whether all FP piping connected to SCI structures is classified as SC II and is designed to maintain its pressure boundary and remain functional during and after an SSE event.

2) Second, Section 3.2.1 does not reflect these additional requirements. FSAR Section 3.2.1 should be revised to identify the specific seismic requirements applicable to the FPS and the sentence on page 18 of 38 should be rewritten to make clear what the seismic requirements are for FP piping connected to SC I structures.

Item C - FP Piping Connected to SC I Structures

25

RAI 378, QUESTION 03.07.02-75

UniStar Response:

1) Seismic classifications of site-specific FP piping have been modified and are identified with design requirements described in response to Item N of this RAI. Revised classifications for FP piping are CS (Note 1), and NSC. CS (Note 1) requires piping to remain functional during and after an SSE.

Site-specific FP piping connected to SC I structures is classified as CS (Note 1). Seismic analysis and design of CS (Note 1) buried piping will follow the same requirements as of SC I piping, outlined in FSAR Section 3.7.3.12, Section 3.8.4.4.5, and Section 3.10 of the AREVA NP Topical Report ANP-10264NP-A.

2) FSAR Section 3.2.1 will be revised to include Seismic Category CS (Note 1) and design requirements applicable to this classification. • Applicable Sections of FSAR, will be revised to identify the specific seismic

requirements of the FP piping attached to SC I structures.

Item C - FP Piping Connected to SC I Structures

26

RAI 378, QUESTION 03.07.02-75

1) In Enclosure 2, page 15 of 38, it states that the buried FP SSC identified in Table 3.2-1 are seismically analyzed using the design response spectra identified in 3.7.1.1.1.4. It states “These piping mains will be designed according to ASCE 4-98, 1983 ASCE Report “Seismic Response of Buried Pipes and Structural Components”, and the AREVA Topical Report ANP 10264, ‘US. EPR Piping Analysis and Pipe Support Design Topical Report’.” The 1983 ASCE report is not identified in FSAR Section 3.7.3.12 which addresses the analysis of buried FP pipe. The applicant is requested to explain this omission and describe what additional requirements from the 1983 ASCE report will be applied to the analysis and design of buried FP pipe and to include this information in Section 3.7.3 of the FSAR.

2) In addition, the AREVA Topical Piping Report only addresses the qualification of ASME III piping (safety class 1,2, and 3). According to Table 3.2-1 of the markup, the FP piping is qualified using the provisions of ANSI/ASME B31.1. The applicant is requested to explain how the AREVA Topical Piping Report is applicable to seismic qualification of the FP piping.

3) Lastly, buried FP SSC are not explicitly identified in Table 3.2-1 even though this is indicated to be the case in the applicant’s response. The applicant is requested to revise Table 3.2-1 to include the identification of buried FP SSC.

Item H – FP Buried Piping

27

RAI 378, QUESTION 03.07.02-75

UniStar Response: Site-specific buried FP piping will be classified as CS (Note 1), and NSC in Table 3.2-1. Seismic analysis and design of CS (Note 1) buried piping will follow the same requirements as of SC I piping, outlined in FSAR Section 3.7.3.12, Section 3.8.4.4.5 and supplemented by response to RAI 333, Q 03.08.04-29.

1. ASCE 1983 Report (Seismic Response of Buried Pipes and Structural Components), & ASCE 4-98, are specifically used to evaluate the effects of seismic waves traveling through surrounding soil. Seismic responses of long, straight buried pipe sections, remote from bends or anchor points, are taken as equal to those of the ground as defined in the 1983 ASCE report. Upper bound maximum axial and bending strains due to seismic wave propagation are calculated using equations provided in ASCE 1983 Report. ASCE 1983 Report will be included in FSAR Section 3.7.3.12.

2. AREVA NP Topical Report ANP-10264NP-A, Section 3.10 describes detailed step by step method of analysis and design of ASME Class 2 & 3 SC I buried piping and is based on among others ASCE 4-98, ASCE 1983 Report and ASME III 2004 and ANSI/ASME B31.1 standards.

3. Table 3.2-1 will be revised to explicitly include buried FP SSC (N handout).

Item H – FP Buried Piping

28

RAI 378, QUESTION 03.07.02-75

In addition to addressing the staff concerns in Items A through M above, applicant is requested to provide the following additional information regarding the seismic design for the CCNPP Unit 3 FPS:

For each SSC that must remain structurally intact under an SSE; must maintain its pressure boundary under an SSE; or must remain functional during and after an SSE the applicant is requested to provide the seismic inputs, type of seismic model, methods of analysis, and the acceptance criteria that are imposed which ensure that the SSC will meet its applicable design requirement and to include this information in the appropriate section of the FSAR.

Item O - Fire Protection SSC

29

RAI 378, QUESTION 03.07.02-75

UniStar Response: • Seismic classification of Site-specific FP SSC have been re-defined & identified

including seismic design requirements in the handout for Item N, as: i) CS (Note 1) and ii) NSC

FP SSC are grouped as follows, and are listed in the handout for Item O:

i) CS (Note 1) Structures - buried pipes. ii) CS (Note 1) Subsystems - HVAC ducts, cable trays, conduits and tubing
