| This report is made under 10 CFR 20.2201(1)(a)(1).  A lead analyzer          |
| containing 6 mCi of Cd-109, used for checking for lead in paint, was stolen  |
| while momentarily unattended in the hall of the Edison Middle School.  The   |
| school authorities and police have been notified.  A reward of $500 has been |
| posted.  There is little threat to the public as readings on contact are     |
| only 100 - 200 R/hr when source is exposed.                                 |
|                                                                              |

| "At 1329 CST, the plant experienced an isolation of the Main Steam Isolation |
| Valves [(MSIV)] which subsequently initiated an automatic reactor SCRAM.     |
| The [MSIV] Closure was part of a Group I isolation which is believed to be   |
| caused by performance of a maintenance surveillance on the Main Steam Line   |
| Tunnel Leak Detection System."                                               |

| The licensee stated that all control rods fully inserted due to the reactor  |
| scram and that the reactor core cooling isolation system was manually        |
| actuated and secured during this event.  There were no emergency core        |
| cooling systems actuations, and none were required.  The licensee's          |

| The licensee also stated that water is currently being supplied to the       |
| reactor vessel via normal condensate and feedwater and that safety relief    |
| valves are being utilized for pressure control.  Containment parameters were |
| reported to be normal, and offsite power is available.  The emergency core   |

| "Investigation into this event has determined that the cause of the MSIV     |

| At 1105 on 12/19/00, a hydraulic line on demolition equipment broke due to a |
| mechanical failure resulting in approximately 1/2 gallon of hydraulic fluid  |
| spilling to the ground.  The equipment was sitting on top of a 5-foot high   |
| mound of rubblized concrete.  Therefore, the hydraulic fluid actually        |
| spilled onto the concrete, but it was reported as being the ground because   |
| the hydraulic fluid had the potential to get to the ground.                  |
|                                                                              |
| The applicable area has been covered, and absorbent material has been placed |
| around the area.  Decommissioning personnel currently plan to dig out the    |
| area of rubblized concrete and place it in a metal shipping container.  The  |
| rubblized concrete was part of the previous containment that had been        |
| removed.  There were no reports of contamination, and there were no liquid   |
| or gaseous releases involved.                                                |
|                                                                              |
| The licensee notified the State of Connecticut at 1350 on 12/19/00.  The     |
| licensee also notified the NRC Region 1 office (John Wray and Maria Miller). |
| At this time, it is not known whether or not a press release will be issued. |

| "At 1305 on 12/19/00 during Low Pressure Service Water (LPSW) testing on     |
| Unit 1, an alarm was received on the operating 'A' Control Room Ventilation  |
| System chiller.  Upon investigation, it was determined that the 'A' chiller  |
| had tripped due to a loss of service water flow to the chiller condenser.    |
| The chiller service water pumps take suction from a Condenser Cooling Water  |
| (CCW) line, which also supplies suction to the LPSW pumps.  The LPSW testing |
| was aborted, and a normal alignment for CCW was completed.  Several attempts |
| were made by Operations and Maintenance to restart the 'A' chiller with no   |
| success.  An attempt was then made to start the 'B' chiller, and it also     |
| tripped.  At 1352, the [Operations Shift Manager (OSM)] determined that no   |
| chillers were operable and declared both trains of Control Room Ventilation  |
| System inoperable.  [TS Limiting Condition for Operation (LCO)] 3.0.3 was    |
| entered at 1352 on [Units] 2 and 3 per [TS] 3.7.16."                         |

| "At [1452] hours, Operations began a controlled shutdown of both Units 2 and |
| 3.  Units 2 and 3 were operating at 100% power in Mode 1 at the start of the |
| event.  Unit 1 was in Mode 6 as part of a refueling outage."                 |

| The licensee stated that the 'A' and 'B' chillers supply the control room    |
| ventilation system for all three units.  Units 1 and 2 share a common        |
| control room.  Unit 3 is located in a separate control room, but it is       |
| served by the same chilled water system and chillers.                        |
|                                                                              |
| The licensee also stated that the TS  LCO requires that at least one control |
| room ventilation system train be returned to service or that the units be    |
| placed in Mode 3 within 12 hours.  The licensee anticipates exiting this LCO |
| within the required time frame.                                              |

| "At 1455 on 12/19/00, Oconee Nuclear Station reported initiation of a        |

| "This shutdown was due to loss of both chillers associated with the chilled  |

| "At 1521, the 'B' chiller was declared operable, allowing Units 2 and 3 to   |
| exit TS 3.0.3 and to stop power reduction at approximately 99%."             |

| UNPLANNED CLOSURE OF STEAM GENERATOR BLOWDOWN ISOLATION VALVES DURING        |
| FUNCTIONAL TESTING OF A STEAM GENERATOR BLOWDOWN TANK LEVEL CONTROL VALVE    |

| "Instrumentation and control personnel were functionally testing the steam   |
| generator blowdown tank level control valve, BT-106, and its associated      |
| solenoid valve, SV-33029.  A non-ESF temperature switch, TS-16218, was       |
| manually actuated to test SV-33029.  This resulted in an unplanned closure   |
| of steam generator blowdown isolation valves BT-2A/MV-32077 and              |
| BT-3B/MV-32080.  These valves have containment isolation functions for a     |
| steam line break inside containment and are also required to close on        |
| auxiliary feedwater system actuation."                                       |

| The licensee stated that all systems functioned as required and that there   |
| was nothing unusual or misunderstood.  The licensee also stated that this    |
| event did not place the unit in a technical specification limiting condition |
| for operation.  The steam generator blowdown isolation valves have been      |
| returned to their normal configuration.                                      |
