| THE LOCATION OF 2 FUEL PINS IN THE SPENT FUEL POOL IS UNKNOWN |
| |
| "As part of the ongoing decommissioning of Millstone Unit 1, a detailed |
| documentation of the fuel currently in the Unit 1 spent fuel pool is |
| underway. 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. SANDIN * * * |
| |
| The licensee is updating this report as follows to include the results of |
| their investigation: |
| |
| "DETAIL: |
| |
| "On October 1, 2001, Northeast Utilities provided its final report on the |
| Millstone Unit No. 1 fuel rod accountability project to DNC (Dominion |
| Nuclear Connecticut). 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. A |
| separate root cause is being prepared by NU for this event. |
| |
| "RECOMMENDED ACTIONS: |
| |
| "Incorporate into the MP1 decommissioning plan, as necessary, any DNC |
| recommendations for additional future spent fuel pool inspections. |
| |
| "ADDITIONAL INFORMATION: |
| |
| "Dominion Nuclear Connecticut (the licensee) will be delivering copies of |
| the final report to NRC Headquarters and Region I offices for placement on |
| the docket today (10/05/01)." |
| |
| The licensee informed the NRC resident inspector. The NRC operations |
| officer notified the R1DO (Conte), NRR EO (Tappert), NMSS EO (Brown), IRO |
| (Wessman), NRR IAT (Skelton), NMSS IAT (Weber), NMSS (Essig), Region 1 |
| (Pangburn), OPA (Jasinski), and Liaison Team (Stauss). |

| UNIT 2 ENTERED TECH SPEC 3.0.3 DUE TO TWO TRAINS OF SERVICE WATER DECLARED |
| INOPERABLE |
| |
| "At 0026 hrs on October 5, 2001, Beaver Valley Power Station Unit 2 |
| experienced a trip of the 'A' Train Service Water (SWS) Pump. 2SWS-P21 C was |
| operating on the 'A' SWS header when the pump tripped on Motor Ground Over |
| Current. Both A and B Train Emergency Service Water Pumps (SWE) auto started |
| as designed and Service Water header pressure returned to normal values. Due |
| to a piping class break, safety/non-safety, between the SWS and SWE systems, |
| the unit entered Technical Specification 3.0.3 due to two trains of Service |
| Water being Inoperable. The unit entered and completed the Abnormal |
| Operating Procedure for Loss of Service Water, and the Bravo Train of |
| Service Water was restored Operable when 2SWE-P21 B was secured and isolated |
| from the 'B' SWS header. 25W5-P21 B continued to operate normally during |
| this event. Technical Specification 3.0.3 was exited at 0037 hrs. The plant |
| is currently stable and operating at 100% power. Technical Specification |
| 3.7.4.1 for Service Water (72-hour action) is applicable, as the only |
| operating pump on the 'A' SWS header is 2SWE-P21A. The Alpha Service Water |
| Pump, 2SWS-P21 A is unavailable due to Intake Structure Bay cleaning. |
| Currently efforts are under way to recover the Intake Bay and restore |
| 2SWS-P21A Operable. It is expected that both trains of Service Water will be |
| Operable within 12 hours. The Non Safety Related Chiller units tripped due |
| to the SWS low pressure conditions, and were recovered shortly there after. |
| No additional failures or equipment challenges occurred as a result of this |
| event." |

| ABSTRACT: A Troxler portable gauge was stolen from a pick-up parked at a |
| residence. An authorized user was returning home late from a job site and |
| knowing he had to go back early the next morning requested permission from |
| the licensee's Radiation Safety Officer to take the gauge home and secure it |
| there. The authorized user's home was closer than the licensee's storage |
| location. Permission was given and the gauge, a Troxler model 3440, serial |
| number 31199, was locked and chained in the bed of the pick-up. 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. A |
| reward is being offered for the gauge which contains 10 millicuries of |
| cesium 137 and 50 millicuries of americium 241/beryllium. |

| MANUAL REACTOR TRIP DURING TESTING |
| |
| "On 10/06/01, testing personnel and the Control Room crew were performing |
| 1BVT-1 .1.7, 'Rod Position Indication System Calibration Verification' and |
| 1BVT-1.1.1, 'Rod Drop Testing' in preparation for reactor startup after Unit |
| 1's 14th Refueling Outage. At 1959 hours, the Control Room operators |
| observed indications of 2 dropped control rods (rod position indication |
| reading zero steps and rod bottom lights on), and entered 1AOP-1.1.8 |
| (Abnormal Operating Procedure - Rod Inoperability). The Reactor Operator |
| opened the reactor trip breakers in accordance with the Abnormal Operating |
| Procedure and the Reactivity Management Plan that included reactivity limits |
| and recommended contingency actions. It was subsequently discovered that the |
| indications were caused by the test crew repositioning knife switches to |
| place the rod drop computer in service. The action and resulting indications |
| were not communicated to the Control Room crew. This event is being reported |
| under 10CFR 50.72(b)(3)(iv)(A), as a Specified System Actuation (RPS), |
| because a valid manual RPS signal (opening the reactor trip breakers from |
| the Control Room) was initiated which was not part of the pre-planned |
| testing in progress. All equipment functioned as expected, and no additional |
| failures or equipment challenges occurred as a result of this event. There |

| UNEXPECTED REACTOR TRIP DURING PLANT STARTUP OPERATIONS |
| |
| ". . . . 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. Cause of this rate trip is not definitively |
| known at this time, rapid event teams to investigate and evaluate the trip |
| have been initiated. Suspected cause is a Rod Control System problem." |
| |
| The licensee notified the NRC Resident Inspector. |

| COMMERCIAL IRRADIATOR FACILITY REPORT REGARDING A SOURCE HANG UP |
| |
| Sterigenics is a panoramic, wet-source storage, commercial, irradiator |
| facility. At approximately 2215 EDT on 10/07/01, a 2.6-megacurie cobalt-60 |
| source got stuck in the unshielded position. The licensee attempted to lift |
| the source rack and had to release the ear out of the cylinder in the cell |
| to free it. The source rack was successfully returned it to its shielded |
| position within approximately 1 hour. There were no personnel radiation |
| exposures or injuries as a result of this event, and there was no source |
| leakage. |
| |
| The licensee is still investigating the cause of this event and has ceased |
| operations until engineering personnel can complete their evaluation. |

| DISCOVERY OF A THROUGH-WALL LEAK AROUND ONE CONTROL ROD DRIVE MECHANISM |
| NOZZLE (REACTOR COOLANT SYSTEM PRESSURE BOUNDARY LEAK) |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "On October 1, 2001, following shutdown for a scheduled refueling outage, |
| Crystal River Unit 3 (CR-3) performed a visual inspection of the Reactor |
| Vessel (RV) Control Rod Drive Mechanism (CRDM) nozzles per NRC Bulletin |
| 2001-01. 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. |
