1.0 INTRODUCTION

1.1 Purpose The purpose of this report is to evaluate the Auxiliary Feedwater (AFW) flow requirements for the Palisades Nuclear Plant. This was done to detennine the capability of an existing High Pressure Safety Injection (HPSI) pump to function as an AFW pump. 1.2 Scope This anaTJsis applies only to the Palisades Nuclear Power Plant. Speeif1cally, it addresses the auxiliary feedwater flow rate quired to automatically maintain decay heat removal but does not encompass subsequent plant_cooldown. Adequate flowrate is the only criteria for acceptance of the pump conversion considered in this* analysis. 1.3 Background As a result of TMI and subsequent studies (References 2.1 and 2.2) the importance of the Auxiliary Feedwater System (AFWS) in mitigating accidents has been highlighted. In light of this, the NRC Staff has made an assessment of the relative reliability of the AFWS at all operating plants for various loss *of main feedwater transients. The Palisades Nuclear Plant was assessed as requiring improvement in its overall level of reliability. One of the main areas of concern was the fact that the AFW discharge lines of the two existing AFW pumps conbined into a single header through which all AFW must flow. To improve the overall reliability .. of the AFWS, it has been proposed that the third existing HPSI pump be converted so as to function as an Auxiliary Feedwater pump. Figure A shows the relative capacities of the HPSI and AFW pumps indicating the somewhat lower flow rate of the HPSI pump.

l. I * -* 2 -1.3 Background

--continued To detennine the capability of the HPSI pump to function as an AFW pump, an analytical evaluation of the AFWS flow requirements for Palisades, was perfonned.

SUMMARY

3ol Acceptance Criteria The analysis was perfonned using the CE Long Tenn Cooling (LTC) plant simulation code to detennine the NSSS response following a total loss of main feedwater. Results were considered acceptable if the secondary sink was maintained as reflected by stable prifl'IClry system temperature and pressure. This resulted in acceptable delivery rates that are lower than the flow rates necessary to match the steam flow required to remove decay heat, as specified in Table 9-11 of the Palisades Final Safety Analysis Report (FSAR) (Reference 2.3). The flow rates described in the FSAR are conservative values which do not credit the steam generatar inventory, which is an additional source of decay heat removal. With the lower flow rates it has been shown that the steam generator liquid volume will decrease during the initial portion of the transients but then subsequently increase as the AFW flow rate "catches up" with the decreasing decay heat. Hence, the steam generator is not drained and primary to secondary heat transfer is not degraded to a point beyond a few degrees increase in hot leg temperature.

  • \,/ * . 3 -3.2 Assumptions The following assumptions were used in the analysis of the total loss of main feedwater flow: 1. The core has been operating at 2650 MW prior to reactor trip. This maximizes the decay heat load to the steam generators (SG). 2. The present AFW pumps (one motor driven and one turbine driven) are unavailable and that the converted HPSI pump is the only source of AFW fl ow. 3. A 120 second time delay from demand to delivery was selected for all cases. 4. The AFW temperat"ure was 100°F and the SG secondary pressure was maintained at 900 psia. 5. The following HPSI flowrates were analyzed:

Case 1: Auxiliary Feedwater (AFW) flowrate of 300 GPM is .. supplied to two steam generators (150 GPM each). Case 2: AFW flowrate of 400 GPM is supplied to two steam generators (200 GPM each). Case 3: AFW flowrate of 325 GPM to one steam generator (no flow to the other SG). 3.3 Results As can be seen in the resulting plots, the minimum secondary inventories. (indicated by wide range level} are on the order of 8 to 20 percent of instrument span*. It can also be noted that the steam generator level is recovered so that the steam generator is not . (Although levels fall below narrow range indication, level can still be monitored due to the fact that Palisades recently installed a wide range level indication systen:i.) Loop temperatures as can be seen, level off _gradually without increasing more than 5°F and without impacting system pressure * *NOTE: The plots prepared by the computer present secondary level in per cent of span between the WR (wide range) level instrument taps. This is not the sane as the value that would be read on the WR SG level indicator. The scale on the WR indicator reads from -138% to 0 to+100%; with 0 to +100% corresponding to the span covered by the NR indicator. -* 4 .;. -

4.0 CONCLUSION

S /jcp. Following a review of the results gathered in the analysis, CE concluded that the HPSI pump is capable of functioning as an AFW pump to automatically maintain a secondary heat sink following a loss of feedwater. In functioning as such the HPSI pump must deliver at least 325 GPH to one steam generator alone or at least 300 GPM to both steam generators (150 GPM each). Available data indicates this is well within the pumps capability with suitable allowance for recirculation., wear and system losses. ! .1 .. U*E 10 X 10 TO " INCH 1 JC 10 INCHES n ICEUFFD.

CPCo letter 8343-057 dated May 7, 1982 tt

Dear Mr. Haskell:

*The following discussion and .the attached diagram illustrates the pump start sequence logic as a function of initiation (AFAS) and AFW flow. *Pump P-8A is actuated by the AFAS left channel where as pump P-8C is actuated by the AFAS right channel. P-8A starts immediately, the P-8C start signal is "blocked" by the delay relay. If AFW flow to at least one SG does not increase to a value above the flow switch set point, and the time delay relay has timed out, pump P-8C will start. -If during the operation of pump P-8C flow to at least one*sG is not achieved and AFAS left channel is present, pump P-8B will start. Bechtel has reviewed CPCo comments regarding auxiliary feedwater pump and isolation valve logics JLG-14l(Q) through JLG-145(Q), all Rev B. Each comment has been addressed and is resolved as follows: , .

, : t wd r: ;: . r I :J l ' I I ! ! t I i

  • Bechtel Associates Professional Corporation Mr. Haskell June 15, 1982 Page JtG-143(Q), Rev B. The two time delay relays, in conjunction with the "not" and "and" gates develop a pulse with a duration of five seconds. The start signal, therefore, goes to zero after five seconds. This is done to prevent lock out and enables manual pump restart. JLG-144(Q), Rev B
  • The start command signal for pump P-8B is developed on JLG-143(Q) and includes AFAS "A". P&ID M-9207(Q), Sheet 2, Rev 0 "LOW-FLOW" instead of "NO-FLOW" is correct. The next revision of M-9207 will be changed accordingly.

All timing intervals indicated on Logic Diagrams JLG-143(Q), 144(Q), and 14S(Q), are approximate. These timing values will be revised and shown on logic diagrams and system functional descriptions accordingly. If you have any additional questions regarding these drawings, please advise.
