TRANSIENT AND STEADY STATE ANALYSIS OF THE lAP AND lBP REACTORRECIRCULATION PUMPS - HOPE CREEK GENERATING STATION
Requested By: Gary Stith, Engineer
Test Conducted By: W. Pryor
INTRODUCTION
The PSE&G Research and Testing Laboratory's Vibration Test Groupwas requested to evaluate the mechanical condition of the lAP andlBP Reactor Recirculation Pumps based on their vibration responsecharacteristics. Specific project objectives as outlined byplant personnel were to: 1) Evaluate the balance condition ofthe RCP rotor assemblies; 2) Determine the cause of the highvibration alarms received in the control room; 3) Investigate thepossibility of RCP vibration contributing to the cracking of thedischarge valve drain line.
The data contained in this report was acquired at the Hope CreekStation between 13 and 15 February 1987, during a unit start-up.This report documents the vibration response characteristics ofthe RCP system over that time period.; As such this reportrepresents a valuable reference from which future analysis andmalfunction diagnosis can be based.
TEST METHOD
The steady state and transient data contained in this report wasacquired from the shaft relative buffered outputs which arelocated on the front panel of the permanently installed vibrationmonitoring system. Shaft vibration was sensed utilizing theinstalled proximity transducers on each pump. This transducersystem measures peak-to-peak shaft vibration i-n mils relative tothe transducer mounting bracket. Signals from the proximityprobes were combined with a once-per-turn keyphasor pulse. Thekeyphasor is necessary for phase angle measurement and variablespeed tracking.

TEST METHOD (cont'd.)
The steady state data presented in the report consists of orbit,timebase, and spectrum information. This data details shaftresponse at several load points. Steady state data provides apowerful tool for evaluating the influences of various rotorpreloads, a wide variety of instability mechanisms, plus a entirearray of rotor response characteristics from simple imbalance tocomplex modal studies.
Transient data was acqhired during a start-up of the unit.Start-up data is presented in the form of bode, polar, andcascade presentation formats. Bode and polar plots are used todetail the synchronous response of the rotating element. Thisdata is important in the identification of rotor balanceresonances and the measurement of system damping characteristics.Cascade information documents excitations outside of the runningspeed range. Cascade data is used in the evaluation of rotorinstabilities such as oil whirl and oil whip, rubs, and vanepassing activity.
The data presented in this report was acquired on magnetic tapeutilizing a 14 channel Honeywell 101 instrument grade FM taperecorder. Vibration data was recorded at a tape speed of 0.9375IPS. At this tape speed the recorder has a frequency responseof DC to 18,750 CPM. The recorded vibration data was subse-quently reduced to hard copy data presentation formats via theBently Nevada ADRE machinery diagnostic computer system. TheADRE system consists of a Bently Nevada DVF2 tracking filter,Hewlett Packard 3582A dual channel spectrum analyzer and a HP9836C desktop computer. Operating software for the system wasdeveloped by Bently Nevada Corporation.
TEST RESULTS AND RECOMMENDATIONS
1. Both RCP rotor assemblies are well balanced at this time.There is currently no need to conduct a trim balance of theunits.
2. The data indicates that shaft runout is a major contributorto the overall vibration levels currently measured at theSmart Monitors. Runout is relatively easy to remedy and canbe corrected during the forthcoming refueling outage. TheResearch and Testing Laboratory is available to discuss thissituation further with the plant and assist in correcting theproblem.

TEST RESULTS AND RECOMMENDATIONS (cont'd.)
3. The high vibration levels are caused by impeller vane passing-activity and occur in two speed ranges. For the lAP pump,these ranges are between 720-800 RPM and 1040-1090 RPM. Onthe lBP pump the high vibration levels exist between700-760 RPM and 1150-1200 RPM. Operation of the equipmentin these speed ranges should be minimized.
4. Experience with RCP systems has shown that high vibrationlevels which- occur in the lower speed range are caused bythe excitation of the pump's first bending resonance by theimpeller vane passing frequency. The presence of impellervane passing activity is considered to be indicative of amachinery malfunction which can limit the long term relia-bility and operation of the pump. It is, therefore, stronglyrecommended that every effort be made to eliminate thisactivity.
5. The specific cause of the high vibration levels measured atthe higher speed range is currently unknown. From the datait appears that this response is due to a structuralresonance. Further testing is warranted during the refuelingoutage to identify and correct the cause of this response.
6. Available data does not allow us to determine if the RC Pumpvibration contributed to the cracking of the discharge valvedrain line. It is possible that pressure pulsations causedby impeller vane passing activity contributed to the failure.Further testing when,the unit is down for refueling isnecessary tormake this determination.

DISCUSSION AND CONCLUSIONS
lAP and 1BP Reactor Recirculation Pumps
Analysis of the RCP rotating element reveals that both Pumpsdisplay similar response characteristics. As a result thefollowing discussion pertains to both pumps unless specificallynoted.
Evaluation of transient and steady state data indicates that bothpumps are acceptable for continued operation under full loadconditions and that both pumps contain rotating elements that arewell balanced The condition of the rotors balance is easilyviewed on the start-up Bode and Polar plots where lX runningspeed information has been corrected for shaft runout. Whencorrected for runout the lAP pump displays approximately 1 milof running speed motion while the lBP pump shows about 2.25 milsof motion due to mass imbalance. This indicates that while somereduction in overall vibration levels could be achieved throughtrim balancing, the high vibration levels noted by plantpersonnel are not due to rotor imbalance. As previously stated,the rotors are well balanced for the speed at which they operate,thus, it is not deemed necessary to undertake a rotor balancingprogram at this time.
Data collected on both rotors does indicate, however, thatmeasured overall vibration levels could be reduced by eliminatingthe shaft runout in the transducer target area. Runout canresult from eccentricity, scratches, non-uniform surface hard-ness, etc. in the area observed by the proximity probe. Theresult of runout -is an error in the vibration levels measured bythe permanently installed monitoring system. From our analysisof the rotors a significant reduction in overall vibration levelscould be expected if the runout was eliminated. It is, there-fore, our recommendation that the probe target area be checkedand corrected for runout during the next refueling outage. Formore information on shaft runout and methods of correction, seethe attached Bently Nevada Applications Note "Glitch, Definitionof and methods for correction, including shaft burnishing toremove electrical runout."' This Applications Note is includedin Tab 3 of this report.
Evaluation of acquired data reveals that the high vibrationalarms are due to vane passing excitations. Vane passingactivity is noted over the entire operating speed of the pumps,but there are 2 speed ranges where there is a significantincrease in overall vibration levels. For the lAP pump theseranges are from 720-800 RPM and 1040-1090 RPM. The response
Technical Mgr., - 5 - June 3, 1987Hope Creek Gen. Sta. - PSE&G Report No. 71125
DISCUSSION AND CONCLUSIONS (cont'd.)
characteristics for the lBP pump are very similar to the lAP pumpexcept that the ranges in which the high vibration occurs differslightly. On the IBP pump high vibration was measured between700-760 RPM and from 1150-1200 PNm. MI-aximum amplitudes throughthese speed ranges can be viewed on Vibration Summary Tables 1and 2.
Previous experience with these and RCP systems of similar designat other stations has shown that the lower speed range highvibration is due to an excitation of the pumps first bendingresonance by the impellers blade passing frequency. Peak ampli-tudes due to the 5X comDonent were measured to approach 3.0 milson the lAP pump and are approximately 4.0 mils on the lBP Pump.Currently the resonance is well damped and should not have animmediate effect on machinery operation. This activity was notedand discussed with the machinery manufacturer during start-uptesting. At that time, it was the manufacturers contention thatthe 5X component was due to the operation of the pumps at off-design conditions (ie. water temperature, pressure and density).They further stated that they would not expect this activity toexist once the unit was operated under design conditions.
The presence of vane passing is considered to be a machinerymalfunction which limits the long term reliability of thepumping system. As a result, it .is our strong recommendationthat engineering and the manufacturer be consulted in order toeliminate the vane passing activity. Until a design change canbe implemented, operation of the pumps in the speed rangespreviously noted should be minimized.
The upper speed range high vibration amplitudes are due to a 15Xrunning speed component. For the lAP pump about 3.0 mils isattributable to this activity and on the lBP pump this vibrationcomponent results in approximately 3.5 mils of dynamic response.From the data it appears that the 15X component is the result ofsome type of structural excitation. At the present time theexact nature of this component is unknown and further testing iswarranted to identify th'e cause and correct for this problem.Until the cause can be identified, machinery operation in thisspeed range should be avoided.
Based on available data, it is impossible for us to determine ifthe RCP vibration contributed to the cracking of the dischargevalve drain line. It is possible however for the drain line tobe excited by pressure pulsations created by the impeller vanepassing frequency. Since this section of piping is small in

DISCUSSION AND CONCLUSIONS (cont'd.)
diameter, long, and unsupported, the resonant frequency of thissection would be prone to structural excitation which could leadto fatigue cracking. To determine the resonant frequency of thepipe is very simple and does not require a great deal of time.It could be tested, by the Research and Testing Laboratory,during the refueling outage and the results compared to thetransient vibration data in order to determine if the RCPresponse contributed to the problem.
