UNUSUAL EVENT DECLARED DUE TO PRIMARY SYSTEM UNIDENTIFIED LEAKAGE GREATER THAN 10 GPM
"Primary system unidentified leakage >10 gpm. Leakage occurred during planned maintenance activity on a NV [Chemical volume and Control System] system demineralizer. The leakage has been isolated at 1108. We are running an NC [primary] system leakage calculation at present prior to terminating the event. All primary system parameters were normal during the event"
The leakage was 11 gpm and was indicated by VCT level dropping.
The NRC Resident Inspector has been notified.

At 1315 EST 11/04/02 Licensee reported termination of the unusual event at 1302 EST based on recalculation of primary system leakage: Total leakage = 0.094 gpm. Identified leakage = 0.017 gpm. Unidentified leakage = 0.077 gpm. Leakage was caused by leak by through isolation valves onto the floor and down a floor drain in the auxiliary building. Notified NRR EO (Reis), R2DO (Landis), IRO (Wessman), AND FEMA (Zapata).

MANUAL REACTOR TRIP DUE TO DECREASING PRIMARY SYSTEM PRESSURE
Licensee reported that PZR spray valve ZPV-100A failed to 46.5% open and mechanically bound. Unsuccessful attempts were made to close the valve manually (from controller) and by isolating instrument air to containment. RCS pressure slowly decreased and a manual reactor trip (all rods fully inserted) was performed at 2005 psig . RCS pressure continued to drop to a low of approximately 1840 psig (1740 psig is automatic trip setpoint). Two reactor coolant pumps were secured in accordance with Emergency Operating Instructions and RCS pressure recovered to 2250 psig (NOP) over a 1.5 hour time frame. A containment entry was performed and the spray valve shut while it was being isolated by manually shutting it's associated isolation valves. Decay heat is being removed by dumping steam to condenser and there is no indication of primary to secondary leakage.
The Licensee has notified the NRC Resident Inspector.

REPORTED LOSS OF I-125 SEED FOLLOWING IMPLANTATION
On 11/4/2002 at approximately 1100 hours, following a procedure to implant I-125 seeds into the prostate of a patient, the licensee counted only 57 of planned 58 seeds implanted. Survey of area, surrounding materials, and counting room did not turn up any indications of the lost seed. The unaccounted for seed contains 382 microcuries. Licensee contacted Region I.
