| DISCOVERY THAT AN M43A1 CHEMICAL AGENT DETECTOR CELL MODULE CONTAINING 250   |
| �Ci OF AMERICIUM-241 HAD BEEN MISSING FROM FT. BRAGG (NORTH CAROLINA) SINCE  |
| APRIL 1996                                                                   |
|                                                                              |
| Late yesterday afternoon (03/16/00), representatives from Ft. Bragg, North   |
| Carolina, requested the U.S. Army in Rock Island, Illinois, to help trace    |
| files for documentation regarding a cell module that was discovered to be    |
| missing from an M43A1 chemical agent detector.  (The cell module contained   |
| 250 �Ci of americium-241.)  The most recent documentation found related to   |
| the missing cell module indicated that it was last seen at Ft. Bragg in      |
| April of 1996.  More recent paperwork has not yet been found.  The licensee  |
| determined this event to reportable at approximately 1200 CST today          |
| (03/17/00).                                                                  |
|                                                                              |
| The licensee hypothesized that the M43A1 chemical agent detector may have    |
| been turned into a maintenance unit at some point.  If the device tested     |
| with bad air flow, the maintenance unit could have replaced several items    |
| including the cell module.  At this time, it is believed that the cell       |
| module in question may have been removed (without any paperwork) and that    |
| the device may have been returned without a replacement cell module          |
| installed.                                                                   |
|                                                                              |
| The licensee stated that there does not appear to be any likelihood that the |
| general public will get involved with this issue.  The licensee plans to     |
| submit a 30-day written report to the NRC Region 3 office.  (Call the NRC    |
| operations officer for licensee contact information.)                        |
|                                                                              |

|                                                                              |
| The module was found on March 23, 2000.  The Operations Center notified the  |
| R3DO (Gardner) and R2DO (Caudle) and NMSS (Sherbini).                        |
|                                                                              |

| Based on a paper trail, the missing item was located at a Defense Logistics  |
| Agency (DLA) facility in Anniston, Alabama.  The M43A1 chemical agent        |
| detector cell module was non-functional and had been removed during          |
| maintenance.  It was then turned in through channels and sent to this depot  |
| facility.                                                                    |

| The NRC operations officer notified the R3DO (Shear), R2DO (Fredrickson),    |
| and NMSS EO (Cool).                                                          |

| "At 0613 [CDT] on 05/23/98, the PSS was informed of a trouble alarm on C-337 |
| Criticality Accident Alarm System (CAAS) 'X' cluster.  Investigation of      |
| trouble alarm revealed that all three modules on [the] 'X' CAAS cluster were |
| in a 'Fault' condition.  The cluster was reset, and the Fault condition      |
| cleared.  This condition was not reported as an event in which equipment     |
| required by the [Technical Safety Requirement (TSR)] is disabled or fails to |
| function as designed as required by 10 CFR 76.120(c)(2).  This event was     |

| DAVID BLACKMORE & ASSOCIATES REPORT TO NRC REGION 1 REGARDING A CRUSHED SOIL |
| DENSITY GAUGE IN POTTSTOWN, PENNSYLVANIA                                     |
|                                                                              |
| At 1345 on 04/27/00, Joe Hughes (the radiation safety officer at David       |
| Blackmore & Associates) notified the NRC Region 1 office that a soil density |
| gauge was crushed at a construction site in Pottstown, Pennsylvania, near    |
| Porter Road.  Mr. Hughes was informed of the event and was en route to the   |
| job site at the time of this notification to the NRC Region 1 office.  Mr.   |
| Hughes called the NRC Region 1 Office to ask advice and was not aware of the |
| event specifics.  The NRC Region 1 office (Noggle) subsequently notified the |
| NRC operations center.                                                       |

| The R1DO (James Noggle) stated that the NRC Office of Nuclear Materials      |
| Safety and Safeguards (George Pangburn and Judith Joustra) had been          |
| informed.                                                                    |

| LOSS OF POWER TO THE TECHNICAL SUPPORT CENTER                                |
|                                                                              |
| At 1505 on 04/27/00, power was lost to the Peach Bottom Technical Support    |
| Center (TSC) as a result of breaker malfunctions during planned electrical   |
| switching.  As of 1605, power had been out for greater than 1 hour           |
| constituting a loss of emergency assessment capability at the TSC.           |
|                                                                              |
| Assessment capability remains in the main control room and the Emergency     |
| Operations Facilities, and communication is still in tact between the        |
| control room and the TSC.  Troubleshooting and restoration activities by     |
| maintenance and operations personnel are currently in progress, and this     |
| condition does not affect either of the operating plants.                    |
|                                                                              |
| The licensee stated that power to the TSC was lost when two breakers failed  |
| to operate during performance of activities to restore power to a normal     |
| lineup following maintenance work on lines that do not normally affect the   |
| TSC.  (However, when this particular lineup change is made, it realigns the  |
| power going to the TSC.)  When the two breakers failed to operate, power at  |
| the TSC was lost.  The licensee stated that the loss of power affected the   |
| TSC only and that no other systems of facilities were affected.              |
|                                                                              |
| The licensee plans to notify the NRC resident inspector.                     |
|                                                                              |

| Power was restored to the TSC at 1710 on 04/27/00.                           |
