UNANALYZED CONDITION REGARDING HHSI FLUSH LINE ISOLATION VALVE LEAKAGE -
While performing a High Head Safety Injection (HHSI) Train-B inservice test, a Plant Operator noted leakage coming through HHSI Flush Line Isolation Valve #SI-0120B. This valve is located on a flush line coming from the discharge of the HHSI pump and directs water to the Safety Injection Pump room sump located within the Fuel Handling Building. The operator investigated and determined that the leakage was due to the valve not being fully seated. The Licensee has come to the conclusion that the estimated leakage through the valve exceeded the allowable value to remain in compliance with 10 CFR 50, Appendix A, GDC 19 limits for Control Room Envelope during the post LOCA Containment recirc phase of a large break LOCA. This condition resulted in an unanalyzed condition that significantly degraded plant safety requiring a notification to the NRC within eight hours per 10 CFR 50.72 (b) (3) ii. Subsequently, flush line valve #SI-0120B has been fully seated, and the leakage stopped. The licensee considers this valve to be operable.
The Licensee notified the NRC Resident Inspector.

STATE LICENSEE, GLOBAL GEO ENGINEERING, REPORTED A TROXLER GAUGE WAS STOLEN FROM A TECHNICIAN'S TRUCK.
A Troxler moisture/density gauge, Model 3430, with nominal activity of 10 mCi Cs-137 and 30 mCi Am-241, was stolen from the back of a flat bed truck sometime after 10:00 pm on 3/26/04, and before 5:00 am 3/27/04. The truck was parked at the technician's residence in West Covina. The technician involved worked late last night, and took the gauge home and left it chained to the flat bed truck overnight. The licensee contacted the West Covina PD. The licensee will be offering a $500 reward for the return of the gauge.
