HPCI SYSTEM INOPERABLE AT FERMI 2

"On 7/13/2003 at 2200 hours, while performing the HPCI Pump Time Response and Operability Test, the HPCI main steam supply outboard containment isolation valve, E4150F003, failed to close. The E4150F003 was declared inoperable and the HPCI main steam supply inboard containment isolation valve, E4150F002, was closed and de-activated per Technical Specifications. Isolating the HPCI main steam supply rendered HPCI inoperable. The E4150F003 the was documented per the site corrective action process. All other ECCS equipment and RCIC are operable. This is being reported under 10CFR50.72(b)(3)(v)(D)."
