ENCLOSURE CONNITHENTS FOR POTENTIAL FOLLONUP FOR THE SPENT FUEL POOL SURVEY PALO VERDE NUCLEAR GENERATING STATION-The licensee identified the potential need to routinely monitor the performance of the fuel pool cooling system.
The licensee was pursuing this issue through the CRDR process.
The licensee committed to address a discrepancy between the UFSAR and procedure 410P-lPC01, "Fuel Pool Cooling," regarding the number of fuel pool cooling pumps needed for various conditions.
Procedure 410P-1PCOl, Section 3.0 stated that a single pump and two heat exchangers should be used to maintain fuel pool temperature less than 145 F prior to initiating SDC.
The UFSAR stated that this lineup should be used to maintain temperature less than 125 F, and that two pumps and two heat exchangers should be used above 125 F.
The licensee committed to review the UFSAR sections pertaining to the SFP to further verify the consistency between actual plant operation and VFSAR descriptions.
