A detailed verification of spent fuel pool content records was | | part of this effort. During this process, workers identified a discrepancy | | in the paperwork relating to the location of two spent fuel pins that were | | removed from a fuel assembly in October 1972. A search is underway; however, | | these fuel pins have not yet been located among the 2,884 fuel assemblies | | containing more than 140,000 fuel pins currently in the spent fuel pool. In | | addition, workers are also searching pertinent records. | | | | "Due to the radiation levels of the fuel pins, if they were removed from the | | spent fuel pool, the use of a shielded cask would have been required and the | | shipment could have only been made to a licensed facility. Any other | | movement of these pins from the site would have been immediately detected by | | the site radiation monitoring system. Therefore, there is a high degree of | | confidence that these pins are not in an unrestricted area and are under the | | control of a licensed facility; either here in the spent fuel pool or | | possibly at a licensed radioactive waste disposal site. As a result, we are | | also confident that no overexposure of workers or members of the public has | | resulted. An independent team with relevant expertise is on-site to assist | | in an ongoing investigation to determine the location of the 2 fuel pins." | | | | The licensee notified NRC Region 1 (Todd Jackson) and the state of | | Connecticut. The licensee intends notifying the NRC Resident Inspector. | | | | * * * UPDATE 1031EDT ON 10/5/01 FROM R. MALONEY TO S.

This project was undertaken after it was determined | | that 2 fuel pins from a Millstone Unit No. 1 spent fuel assembly could not | | be accounted for. The NU project team conducted extensive inspections of the | | Millstone Unit No. 1 spent fuel pool as well as comprehensive reviews of | | material accountability and waste shipment records and interviews of | | personnel historically involved with these activities. On the basis of this | | report, DNC concludes it is unlikely that the pins are in the Millstone Unit | | No. 1 fuel pool. The investigation into the disposition of the pins found no | | evidence to indicate that the pins were diverted and concluded that the pins | | were most likely intermingled with other contaminated material removed from | | the Unit No. 1 spent fuel pool and shipped to a licensed low level waste | | repository. The report concludes, based on a study performed by a reputable | | expert, that the health and safety of the public has not been adversely | | impacted by this condition. | | | | "This condition is reportable under 10CFR70.52(a) as a loss of special | | nuclear material. | | | | "ACTIONS TAKEN: | | | | "A team of DNC personnel has reviewed the report and interviewed members of | | the NU project team to obtain clarifications and additional information.

The | | pick-up, which did not have a canopy, was parked in the residence's drive | | way on the evening of October 4. The authorized user discovered early the | | next morning that the chain had been cut and the gauge stolen. Neighbors | | reported hearing noises about 11:45 PM that night. The theft was reported | | to the local police, the licensee's corporate RSO and to the Department.

This event occurred at 0950 hours this morning (10-7-01). Currently | | the Unit is in Mode 3 with all systems normal. At the time of the trip the | | unit was at approximately 8 % power (by RCS AT indication, about 6 to 7 % on | | Power Range Nuclear Instrumentation) in power ascension and was just | | preparing to roll the main turbine. | | | | "RCS Tavg was noted to decrease below the normal 547 �F no-load post-trip | | value to about 535 �F by the Reactor Operator monitoring the temperature. At | | the time of the trip one main feedwater pump was supplying the Steam | | Generators (SG), with low-flow feedwater pre-heating in service. Main | | feedwater isolated on the trip with the SGs being supplied post trip by the | | motor driven Auxiliary Feedwater (AFW) Pumps. The RCS cooldown was | | attributed to the #4 SG AFW flow control valve not closing as expected on | | high flow thus allowing too much flow to #4 SG, as well as steam that was | | still being supplied to low flow feedwater preheating. Operator actions | | taken in response to the cooldown were to close the main steam stop valves, | | and review AFW valve positions so as to limit steam flow from, and feed flow | | to, the SGs. These actions were completed by 0959 hours, and were sufficient | | to maintain temperature control. RCS temperature shortly recovered to 547 �F | | at about 1032 hours, 10-7-01. No other significant abnormalities were noted, | | pressurizer pressure decreased in response to the temperature transient, and | | the subsequent RCS shrink caused RCS letdown to isolate on low pressurizer | | level. The plant is presently stable in Mode 3. No other RPS or SI setpoints | | were exceeded due to the trip and subsequent temperature transient. All | | other systems and equipment functioned normally. | | | | "The initiating RPS signal was a high Power Range Nuclear Instrument Rate | | Trip on 2 out of 4 channels.

The inspection revealed evidence of boric acid buildup around one | | CRDM nozzle (#32). No other CRDM nozzle showed similar boron buildup. | | After the RV head was removed and placed on the storage stand, additional | | inspections were performed. At approximately 1610 on October 8, 2001, | | Ultrasonic Test (UT) revealed a through-wall indication. This confirms that | | the boron deposits around CRDM #32 indicate a Reactor Coolant System (RCS) | | pressure boundary leak. This condition is consistent with industry | | experience with Primary Water Stress Corrosion Cracking (PWSCC) in similar | | components that have been evaluated as part of the NRC Generic Letter 97-01 | | and NRC Bulletin 2001-01. Additional nozzles are being examined by UT in | | accordance with CR-3's response to NRC Bulletin 2001-01. This condition did | | not pose a significant safety risk during plant operation. CR-3 plans to | | perform repairs during the current refueling outage. Since the condition | | resulted in leakage through the RCS pressure boundary, it is being reported | | as a non-emergency [8-hour] report in accordance with 10 CFR | | 50.72(b)(3)(ii)(A) and 50.73(A)(2)(II)." | | | | The licensee notified the NRC resident inspector. | +------------------------------------------------------------------------------+
