FAILURE OF A MAIN STEAM LINE DRAIN PRIMARY CONTAINMENT ISOLATION VALVE TO COMPLETELY OPEN DUE TO LOOSE TORQUE SWITCH WIRE CONNECTIONS
The following text is a portion of a facsimile received from the licensee:
"During plant shutdown, primary containment isolation valve MO-2373 failed to properly function. The failure was caused by loose torque switch wire connections which caused a failure of the valve to completely open. Improper electrical connections could have prevented full closure of the valve. Therefore, the valve was determined to be inoperable prior to the repair. ([The] valve has been repaired.) The safety function of the redundant primary containment isolation valve was available."
The licensee plans to notify the NRC resident inspector.

AREA CONTROL ROOM (ACR) ALARM POWER LOST DUE TO A FAILURE IN THE POWER TRANSFER SWITCH
"At 1610 on 08-30-00 the PSS was informed of a C-331 CAAS Cluster J Trouble alarm. Investigation of trouble alarm revealed that C-331 CAAS Horns solenoids had lost DC power. The C-331 ACR DC alarm power was lost due to the failures in the power transfer switch. Contacts fused together and a solenoid failed which allowed the transfer switch to reposition to the mid (no power) position and prevented repositioning to the emergency power position. Since the CAAS horns did not have power, they were unable to perform the intended safety function, rendering the system inoperable for audibility. The system is required to be operable according to TSR 2.4.4.7.b for the current mode of operation. The horns were without power (inoperable) for approximately 30 minutes until the transfer switch was physically forced to the emergency power position.
This event is reportable under 10 CFR 76.120(c)(2) as an event in which equipment required by the TSR is disabled or fails to function as designed.
The NRC Resident Inspector has been notified of this event.

LOSS OF ONE I-125 SEED, 0.55 mCi
The licensee discovered 1 of 65 iodine-125 seeds missing when installing them in an applicator for a permanent implant on 8/17/00. Multiple surveys failed to find the seed if present in the shipment. The shipment was received on 8/15/00 and surveyed, but not opened until the applicator was ready to be loaded. The licensee contacted the manufacturer, Uramed Company, of Norwood, MA about the missing seed. The manufacturer could not determine that they had not sent 65 seeds. The seed is considered lost, probably in the hot lab of the hospital, and the licensee does not consider it to be a serious health risk.
A written report will be submitted to the NRC.
