HPCI INOPERABLE DUE TO ERRONEOUS INDICATION ON FLOW INDICATING CONTROLLER
"At 0225 EDT on September 3, 2012, with the James A. Fitzpatrick Nuclear Power Plant (JAF) operating at 93% reactor power, High Pressure Coolant Injection (HPCI) was declared inoperable due to abnormal indication on the HPCI Flow Indicating Controller (FIC). The FIC was found to be indicating a HPCI System flow rate of 700 gpm while the system was in the standby lineup. Under these conditions, the capability of the system to achieve the required flow rate cannot be assured.
"This failure meets NRC 8 hour reporting criterion 10CFR50.72(b)(3)(v)(D). Reactor Core Isolation Cooling (RCIC) and other Emergency Core Cooling Systems (ECCS) remain operable.
"The NRC Resident Inspector has been notified."
* * * UPDATE AT 1418 EDT ON 9/4/12 FROM DeFILLIPPO TO HUFFMAN * * *
"The improper HPCI flow indication was determined to be due to minor air intrusion following restoration of the system after maintenance. The flow transmitter for the HPCI system was repeatedly vented with no air observed. The HPCI system has been restored to a normal standby line-up and is OPERABLE as of 9/4/2012 at 1415 EDT."
The NRC Resident Inspector has been notified. R1DO (Conte) notified.
