| "The licensee called to report that 105 iodine-125 seeds totaling 336 |
| millicuries were missing. The seeds were delivered to the hospital by |
| Airborne Express on 8/29/01 and records indicate they were received by a |
| purchasing clerk at approximately 2:00 p.m.. A prostate implant was |
| scheduled for the morning of 8/31/01. When the radiation therapy |
| technologist went to retrieve the seeds from the nuclear medicine |
| department. the nuclear medicine technologist was unaware that any seeds had |
| been delivered to the hospital. The clerk who signed for the seeds is not at |
| the hospital today and on vacation until Tuesday. The housekeeping staff |
| member who cleaned the area on 8/29/01 does not recall seeing any container |
| fitting the description of the one in which the seeds were packaged and |
| delivered. The Nuclear Medicine Department and the Radiology Department have |
| been searched and the package not located. The dumpsters were emptied and |
| sent to the landfill prior to discovery of the missing sources. An |
| investigation is underway at the hospital. State radiation control personnel |
| will conduct an onsite investigation." |

| AGREEMENT STATE REPORT - STOLEN NUCLEAR GAUGE FOUND |
| |
| "A yellow box with a Yellow II label was found and Hazmat responded to the |
| scene. The box was found abandoned in a dumpster at an apartment building. |
| Hazmat's radiation survey meters indicated the presence of radioactive |
| material. However, the radiation levels indicated were inconsistent with |
| readings expected from a gauge. It was later determined the Hazmat team had |
| confused �R with mR and the readings were much lower than earlier believed. |
| |
| "The city requested assistance to identify the owner of the gauge and |
| possibly to take possession of the gauge. Because Houston was recently |
| flooded, the city's basement area (with a lead lined vault was severely |
| damaged and could not be used to temporarily secure the gauge. |
| |
| "It was determined that the gauge belonged to ATSER Corporation (L04741). A |
| former employee reported carrying it in his vehicle and it was stolen along |
| with the vehicle. The company is still investigating. The gauge is a |
| Humboldt, s/n 3612. The source serial number of the Cs-137 source is 9842GQ |
| and the Am-241/Be source is NJ03905." |

| REACTOR MANUALLY SCRAMMED FROM 100% DUE TO LOW VESSEL LEVEL |
| |
| This report is being made per 10CFR50.72(b)(2)(iv)(B) RPS actuation (4 hour |
| notification for U-2), 10CFR50.72(b)(2)(iv)(A) ECCS Injection/Actuation (4 |
| hour notification for Unit 2), and 10CFR50.72(b)(3)(iv)(A) System Actuation |
| not including RPS (8 hour notification for Unit 1 and 2). |
| |
| At 1728 CST. Monday, 9-3-01,U-2 was manually scrammed. Initiating event |
| appears to be a loss of Bus 241Y, which resulted in a loss of feedwater. |
| The reactor was manually scrammed at approximately 20 inches before the |
| automatic scram setpoint for low vessel water level. All rods fully |
| inserted. |
| |
| The Reactor Core Isolation Cooling (RCIC) and High-Pressure Core Spray |
| (HPCS) systems automatically started and injected and restored Reactor |
| Pressure Vessel (RPV) level. |
| |
| A primary containment-level 2 isolation occurred and the Reactor |
| Recirculation pumps tripped at minus 50 inches as expected. Unit 1 was |
| affected due to standby gas treatment auto start and the reactor building |
| vent system isolation. |
| |
| The lowest Reactor water level reached was minus 55 inches (106 inches above |
| the top of active fuel) as indicated by the Division 2 instrumentation and |
| was recovered to normal level with RCIC and HPCS within a few minutes. |
| Approximately 10,000 gallons of water was injected. |
| |
| Bus 241Y was automatically re-energized from the (0) Common Diesel |
| Generator. |
| |
| Dry-well pressure increased due to the expected loss of primary containment |
| cooling. The highest pressure reached was approximately (1) one psig. |
| Primary Containment Cooling has been restored. There are no indications of |
| a leak inside the primary containment. |
| |
| RPV pressure is being controlled at 800 to 1000 psig by the use of RCIC. |
| Main Steam Line drains, and manual operation of Safety Relief Valve (as |
| necessary). RPV level has been restored to normal and feedwater is being |
| used. |
| |
| Subsequent in the Reactor Scram, the 2A RHR Pump failed to start when |
| manually initiating from the Main Control Room (for suppression pool |
| cooling). |
| |
| System isolations have been restored with exception of reactor water cleanup |
| and the Reactor Recirculation Hydraulic Power Units on U-2. |
| |
| The station is taking action to investigate the cause of the initial loss of |
| 241Y and the unrelated failure to start of the 2A RHR pump. At this time, |
| there appears to be a blown fuse for the 241Y bus Under Voltage logic which |
| prevented the 2A RHR pump from starting. |
| |
| The plant is stable. |
| |
| The NRC resident inspector has been notified. |
