| MAJOR LOSS OF EMERGENCY SIREN CAPABILITY DUE TO ADVERSE WEATHER CONDITIONS |
| |
| "On February 5, 2001 at 1807 it was determined that 24 of 44 Emergency |
| Sirens in the southern Chester County area were inoperable due to the storm |
| passing through the area. Power was lost to these sirens. This constitutes |
| approximately 55% of the sirens in a localized area. |
| |
| "There are currently a total of 34 of 165 sirens inoperable in the EPZ due |
| to the storm or approximately 21%. Power restoration to the area is in |
| progress. Estimated time to restore all the sirens is not known at this |
| time. |
| |
| |
| "Current Siren Status |
| |
| Berks County 1 Inoperable |
| Montgomery County 7 Inoperable |
| Chester County 26 Inoperable |
| |
| There are 165 Sirens total in the EPZ." |
| |
| The licensee will inform the NRC resident inspector. |

| PRIMARY CONTAINMENT DECLARED INOPERABLE |
| |
| Primary Containment was declared inoperable at 0148 CST on February 6, 2001, |
| due to the failure of meeting the acceptance criteria for the suppression |
| chamber to drywell vacuum breaker operation. |
| |
| While performing the 31 day surveillance, PC-AO-NRV30, suppression chamber |
| to drywell vacuum breaker failed to indicate full close. The valve was |
| subsequently stroked a second time and full closure indication was received. |
| Estimated time of 2 minutes and 6 seconds when valve did not indicate full |
| close. During this time frame when the valve was not indicating full close, |
| Primary Containment was inoperable. Upon full closure of the valve, Primary |
| Containment was returned to operable status. |
| |
| Engineering continues to evaluate the condition. TS action statement of LCO |
| 3.6.1.8 B, requires the vacuum breaker to be closed in 12 hours. Required |
| action not completed in the completion time requires the reactor to be in |
| Mode 3 (Hot Shutdown) in twelve hours in Mode 4 (Cold Shutdown) in |
| thirty-six hours. |
| |
| The NRC Senior and Resident Inspectors have been notified. |

| AGREEMENT STATE REPORT INVOLVING A MISSING DENSITY GAGE |
| |
| The Illinois Department of Nuclear Safety reported that a general license |
| density gauge source used by Best Food in their Summit/Argo facility was |
| missing. The source, a 100 mCi Am-241, was installed in an Industrial |
| Dynamics model CI-2C series density gauge. The device without the source, |
| i.e., detector, was in storage in a vault and not in use at the time. The |
| last known presence of the source was on 11/3/97. State inspectors observed |
| that the source was missing on two separate occasions (12/7/00 and 1/5/01) |
| during construction activities. Best Foods conducted extensive interviews |
| with current employees and was not able to determine the whereabouts of the |
| source. A consultant was hired by the company to assist in the |
| investigation. After surveying about 200,000 sq. ft. the consultants |
| speculated that source was either disposed of as scrap or returned to the |
| manufacturer with no record keeping or possibly stolen. The manufacturer |
| who is located in Torrance, CA was contacted and they too have no record of |
| a source return. Best Foods intends to continue their investigation and the |
| State of Illinois is available to assist, as requested. There are no plans |
| at the present to involve law enforcement at this time. The manufacturer's |
| specification indicates an exposure of 5 mR/hr at 15 inches from this |
| unshielded alpha source. The State of Illinois notified the NRC |
| R3ASO(Lynch). |

| ABSTRACT: An authorized user had taken his work equipment home with him in |
| preparation for an early start to a temporary job site. At approximately |
| 5:45 AM the authorized user loaded his work truck with his equipment, |
| including a CPN model MC-3DR portable gauge, serial number MD0069648, which |
| contains 10 millicuries of cesium 137 and 50 millicuries of americium |
| 241/beryllium. The gauge, in its orange transport box, was loaded into the |
| back of an open-bed full-size Chevy pickup and secured to the bed of the |
| truck with a cable and lock. The authorized user left his truck running |
| and went back into the house to finish a cup of coffee; when he came out |
| again his truck was gone. He reported the theft to the King County Sheriff |
| and to his RSO. The Washington Department of Health was notified about |
| 11:45 AM. The Department advised the licensee to offer a reward. As of |
| this report (2 PM, February 6), the vehicle and gauge are still missing. |
| |
| What is the notification or reporting criteria involved? WAC 246-221-240 |

| TURBINE GENERATOR LOCKOUT - REACTOR TRIP |
| |
| A turbine generator lockout caused a unit 2 reactor trip. All rods fully |
| inserted. A loss of main condenser vacuum caused operators to shut the Main |
| Steam Isolation Valves. Decay heat is being removed by use of the steam |
| generator atmospheric dumps. The steam generators were initially fed by the |
| auxiliary feedpumps, but are now being fed using the normal feedwater |
| system. The plant is stable in mode 3. |
| |
| The cause of the turbine generator lockout is not known. The loss of |
| condenser vacuum was caused by the cross over steam dumps opening. These |
| valves opened because of a turbine overspeed condition, believed to have |
| occurred as the turbine was unloaded because of the generator trip. |
| |
| The licensee notified the NRC resident inspector. |
