| "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.                         |

| 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.                                                            |

| 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             |

| 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.     |
|                                                                              |

| 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.          |
|                                                                              |
