MR Number: 2-94-0092 Turkey Point 3 4 Date: 11/04/94 Miami,Florida Dockets: 50-250,50-251 PWR/W-3-LP,PWR/W-3-LP Subject: CONDITIONS OUTSIDE THE DESIGN BASIS Reportable Event Number: 27982 Discussion: The licensee made two one-hour notifications on 11-3-94 (27982 and 27980). The first was due to an operating error where both Unit 3 (3A and 3B) SI pumps were inadvertently placed in the pull to lock position after testing rather than stopped and then returned to auto. The licensee's investigation is ongoing. However, they believe this condition lasted for about 2 hours (between 9:30 - 11:30 a.m. on 11-3-94). The Unit 4 4A SI pump was out of service for testing; however it was available. The Unit 4 4B SI pump was operable for Unit 3. The two SI pumps on each unit can be used on either unit. The Unit 3 TS requirements are 3 SI pumps, and a 72-hour Tech Sepc Action Statement (TSAS) exists for 2 pumps. The licensee reviewed the event with each shift, increased test oversight, modified the test procedure, and placed caution tags on the shared equipment. Testing recommenced and was successful during the midshift on 11-4-94. Unit 3 is in Mode 1. The second one-hour call was due to a design deficiency in the Unit 3 and 4 load sequencers. During a Unit 4 LOOP/LOCA test, the 4A sequencer failed to start the 3A SI pump. The licensee traced this condition to a design fault where at certain times, with the sequencer in an auto-test mode, the sequencer would not function. All four sequencers were placed in a condition where the sequencer test mode was turned off. The licensee previously operated this way from November 1991 to December 1992. The licensee is performing an engineering and safety evaluation, has briefed operators on this condition, has modified logs to locally check sequencer operation, and is performing a test verification and validation program on a sequencer simulator that is available in the training center. The licensee has concluded that the sequencers will function in this mode and has verified this operation through satisfactory repeat of the safeguards test. The licensee intends to continue monthly surveillance testing of each sequencer. Unit 4 is in Mode 5. Regional Action: The resident inspectors and a regional inspector are onsite following the safeguards testing on Unit 4, the sequencer design issues and testing programs, and the licensee actions relative to the operating error.

EST, THE LICENSEE EXPERIENCED AN INADVERTENT INITIATION OF CONTAINMENT SPRAY. TECHNICIANS HAD COMPLETED TESTING ON MOV-7064, CONTAINMENT SPRAY ISOLATION VALVE, HOWEVER, THEY HAD LEFT THE VALVE AT MID-POSITION RATHER THAN ITS REQUIRED CLOSED POSITION. OPERATORS WERE IN THE PROCESS OF OPENING THE VFP-29 VALVE TO RESTORE FIRE HEADER TO THE CONTAINMENT SPRAY LINE WHEN PERSONNEL INSIDE CONTAINMENT NOTED WATER COMING OUT OF THE CONTAINMENT SPRAY NOZZLES. THE VFP- 29 VALVE WAS IMMEDIATELY CLOSED. THE LICENSEE ESTIMATES THAT APPROXIMATELY 100 GALLONS WAS SPRAYED INTO THE CONTAINMENT AND COLLECTED AT THE CONTAINMENT SUMP. ONLY A FEW ENVIRONMENTALLY QUALIFIED COMPONENTS WERE WETTED BY THE SPRAY INITIATION; HOWEVER, SEVERAL AREAS OF THE SPHERE BECAME CONTAMINATED. THE LICENSEE HAS SUSPENDED ALL WORK ASSOCIATED WITH CHANGING PLANT CONFIGURATION AND CLEANED UP THE AREAS THAT WERE CONTAMINATED. Regional Action: THE RESIDENT INSPECTORS WILL CONTINUE TO OBSERVE AND EVALUATE THE LICENSEE'S ACTIONS.

MR Number: 3-94-0204 Braidwood 2 Date: 11/04/94 Braceville,Illinois RI (E. DUNCAN) Dockets: 50-457 PWR/W-4-LP Subject: MECHANICAL FAILURE OF COOPER-BESSEMER EMERGENCY DIESEL GENERATOR Reportable Event Number: N/A Discussion: At about 10:00 p.m., on November 3, 1994, while cooling down the 2B emergency diesel generator (EDG), following post-maintenance testing, the EDG tripped on high connecting rod bearing temperature. The licensee's preliminary investigation found a fractured piece of the bearing cap for the piston end of the 1L connecting rod, in the EDG sump. One sheared fastener, and some nicks and scratches of the diesel internals have also been found. The high connecting rod bearing temperature sensor was found to be sheared off, explaining the trip. The licensee has called in representatives of Cooper-Bessemer to assist with their investigation, and is developing a troubleshooting plan. Regional Action: Region III will dispatch one specialist inspector to the site today, and the resident inspector is following up on this occurrence.

MR Number: 3-94-0205 Palisades 1 Date: 11/03/94 Covert,Michigan ENS 50.72 (b) (2) (vi) Dockets: 50-255 PWR/CE Subject: POTENTIAL THREAT Reportable Event Number: 27981 Discussion: The licensee was notified by the South Haven, MI Police Department that they had received a report from the Van Buren County Mental Health Department that a counselor had just completed an interview with an individual who had self-referred himself for help. The counselor concluded that the person was a threat and "homicidal." The counselor also reported that the individual had stated that he knew how to make bombs, had a pick-up for carrying them and knew exactly where the dry cask storage facility was at Palisades and how to crash the gate. He made no direct threat of action, but left the counselling facility. The licensee implemented appropriate additional security measures to address the potential vehicle threat and notified several surrounding police departments. The local FBI Resident Agent lent assistance. The FBI agent and another mental health counselor interviewed the individual by phone at home. They concluded that the individual posed no imminent threat to Palisades. The licensee will continue the additional security measures pending final resolution of the matter on November 4, 1994. Regional Action: The Resident Inspector verified the additional security measures onsite, the Region III Safeguards Staff monitored the licensee's activities and notified the Information Assessment Team. Followup evaluation of the individual on November 4, 1994 will be monitored by the Safeguards Staff. Contact: J R CREED (708)829-9857
