Morning Report for May 9, 2001
Headquarters Daily Report MAY 09, 2001 *************************************************************************** REPORT NEGATIVE NO INPUT ATTACHED INPUT RECEIVED RECEIVED HEADQUARTERS X REGION I X REGION II X REGION III X REGION IV X PRIORITY ATTENTION REQUIRED MORNING REPORT - REGION I MAY 9, 2001 Licensee/Facility: Notification: New York Power Authority MR Number: 1-01-0010 Indian Point 3 Date: 05/09/01 Buchanan,New York Dockets: 50-286 PWR/W-4-LP Subject: LOSS OF SPENT FUEL POOL COOLING AT INDIAN POINT 3 Discussion: On May 8, 2001, at approximately 2:40 a.m., with the plant shut down and the reactor core completely offloaded into the spent fuel pool (SFP), flow was lost in a system supplying the secondary heat sink for SFP cooling due to a loss of the make-up water supply to the SFP cooling tower. The SFP cooling tower make-up basin volume decreased to the point that the operating SFP cooling tower pump cavitated resulting in the backup SFP cooling pump, which was circulating SFP water through the Backup SFP cooling heat exchanger, tripping on a protective function related to the differential pressure between the backup and cooling tower systems. At the time flow was lost in the SFP, SFP temperature was approximately 150 degrees F. Flow was reestablished within approximately 50 minutes, during which time SFP temperature rose about five degrees F. The five-degree rise in SFP temperature represented a full core offload that had occurred approximately 45 hours prior to the failure and about 242 hours since the shutdown of the reactor. IP3 determined that the event was not reportable. NRC is following licensee activities and is evaluating appropriate response. Contact: Peter Drysdale (914)739-8565 Curtis Cowgill (610)337-5233 _
