The devices were being used by troops assigned to Ft. Sill, Oklahoma, conducting a rotation at Ft. Irwin, California. The devices had been removed from a transport vehicle by an individual at the completion of the rotation, secured in double plastic bags and placed next to other ordinance containers for the subsequent return shipment to Ft. Sill. The individual left the bagged devices unattended and upon return discovered the bags had been removed, presumably as part of a normal trash collection. The licensee reported in subsequent conversations that the items were possibly disposed of in an area landfill as normal trash. The licensee further reported that personnel from Ft. Irwin are attempting to locate the landfill and retrieve the devices. The licensee indicated that the devices and sources were not damaged and no apparent contamination was sustained by personnel. The licensee submitted a written report to NRC dated November 7, 1995. Thorium-232 is currently authorized under NRC License Number 29-01022-14, Ft. Monmouth, New Jersey (Region I). Regional Action: Region I and NMSS were notified. Region III will continue to monitor licensee location/retrieval efforts. Contact: T. KOZAK (708)829-9866 S.

MR Number: 3-95-0169 Dresden 2 Date: 11/13/95 Morris,Illinois RIA VIA LAN Dockets: 50-237 BWR/GE-3 Subject: REFUELING OUTAGE DELAY ON UNIT 2 DUE TO BUDGET CONCERNS Discussion: On November 10, 1995, the licensee announced that all further work efforts on the Unit 2 refueling outage were on hold. Dresden Unit 2 has been in a refueling outage (D2R14) since June 2, 1995. The outage was initially expected to last about 100 days; however, emerging work items and a slow work control process has continued to delay outage completion. This action was taken because of continued increasing outage scope growth and budgetary concerns. Work in progress will be placed in a safe condition (restored or completed) and all work packages will be collected. All Unit 2 fuel was off-loaded at the start of the outage and remains in the spent fuel pool. The licensee plans to walkdown all work packages, reschedule, and remanload the entire outage. Work on the D2R14 outage has been tentatively scheduled to restart after the first of the year. Regional Action: The resident inspectors continued to monitor licensee refueling activities.

MR Number: 3-95-0170 Perry 1 Date: 11/13/95 Perry,Ohio SRI VIA PC Dockets: 50-440 BWR/GE-6 Subject: PLANT SHUTDOWN DUE TO PARTIAL LOSS OF DRYWELL VENTILATION Discussion: On November 11 at 11:43 p.m. EST the licensee disconnected the main generator from the grid as part of a plant shutdown to allow replacement of the two lower drywell ventilation fans. The plant is expected to be shut down for about 8 days and additional preplanned work is in progress. On November 9 at about 2:25 p.m. one of the lower drywell fans tripped on electrical overload. The standby fan started as expected, however there were indications that it was not moving air. Temperatures in the reactor vessel skirt area quickly increased from about 100 degrees F to about 200 degrees F. Bulk drywell temperature increased slightly to about 140 degrees and stabilized below the Technical Specification limit of 145 degrees F. About 2.5 hours later as the inspectors observed licensee troubleshooting preparations in the control room, the second fan tripped on electrical overload. A small increase (about 0.2 gpm) in unidentified leakage (drywell floor drain sump) was also observed. The licensee established its forced outage management organization in case a shutdown was necessary. Licensee engineering evaluations concluded that the increased area temperatures did not threaten plant safety. On November 11 the plant manager ordered plant power reduced to allow inspection of the fans and the drywell in general. During the inspections, the first fan that tripped appeared normal. The other fan had lost all its blades. The licensee is still attempting to determine the root cause of the problems with the ventilation system fans. After the inspection the licensee decided to take the plant to cold shutdown and replace both fans. Regional Action: Resident inspector follow up. Contact: R. D. LANKSBURY (708)829-9631 _ REGION IV MORNING REPORT PAGE 4 NOVEMBER 13, 1995 Licensee/Facility: Notification: Wolf Creek Nuclear Oper. Corp. MR Number: 4-95-0140 Wolf Creek 1 Date: 11/13/95 Burlington,Kansas Telephone Call to SRI Dockets: 50-482 PWR/W-4-LP Subject: PARTIAL LOSS OF OFFSITE POWER Discussion: On November 10, 1995, at 7:42 p.m., the startup transformer lost power, deenergizing the Train B engineered safety features transformer and the Train B Class 1E 4160 volt bus. Coincidentally, the west bus of the site switchyard, one of the offsite power sources, also deenergized. This started the Train B emergency diesel generator, actuated the shutdown sequencer, and started the turbine driven auxiliary feedwater pump. Operators verified that all equipment actuated per plant design, and that the plant condition did not require an activation of the emergency plan. The licensee reported this event per 10 CFR 50.72 at 11:13 p.m. System operations personnel inspected the switchyard and found a bad gasket on the control box for air break Switch 345-163, the switch feeding the startup transformer from the west bus. Moisture entered the control box, shorted out contacts and energized the motor which opened the switch. This switch was not designed to be opened under load, and has no protective features. After further inspection, technicians found no additional damage. Operators restored the plant to a normal full power lineup, and exited all action statements associated with this event on November 11, at 9:33 a.m. Further corrective action included opening the circuit breakers for air break switch motor operators associated with the main generator output breaker and offsite power supplies to the class 1E 4160 volt buses. Regional Action: The SRI is monitoring licensee activities. Contact: F. Ringwald (316)364-8653 _
