| AUTOMATIC REACTOR SCRAM DUE TO ISOLATION OF THE MAIN STEAM ISOLATION VALVES |
| DURING THE PERFORMANCE OF MAINTENANCE/SURVEILLANCE (Refer to event #37616 |
| for details regarding an additional reactor scram.) |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "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 plant is stable, and there were no other abnormal occurrences in |
| conjunction with this event." |
| |
| "Since closure of the [MSIV] is an actuation of the Reactor Protection |
| System, this condition is being reported pursuant to 10CFR50.72(b)(2)(ii)." |
| |
| 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 |
| investigation is currently ongoing. |
| |
| 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 |
| cooling systems are also available if required. |
| |
| The licensee notified the NRC resident inspector and the State. |
| |
| ***** UPDATE AT 1357 EST ON 12/19/00 FROM DALE SHELTON TO LEIGH TROCINE |
| ***** |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "This is an Update to [...] provide current status of investigation and |
| repairs." |
| |
| "Investigation into this event has determined that the cause of the MSIV |
| isolation was performance of a Channel Functional Test of the Division 2 |
| Main Steam Line Tunnel Ambient Temperature channel at the same time that an |
| unidentified failure of a Digital Signal Conditioning (DSC) card in the |
| circuitry for the Division 1 Main Steam Line Tunnel Ambient Temperature |
| channel existed. This resulted in satisfying the 2 out of 4 logic for the |
| MSIV isolation." |
| |
| "Plans are still being developed for repair the DSC card. Although |
| Technical Specifications would allow entry into Mode 2 prior to repair, a |
| decision has not yet been made if the card will be repaired prior to entry |
| into Mode 2. The Facility Review Group will review any repair plans that |
| would be implemented in [Modes] 1 or 2." |
| |
| The licensee notified the NRC resident inspector. The NRC operations |
| officer notified the R3DO (Tom Kozak). |

| OFFSITE NOTIFICATION REGARDING A 1/2-GALLON HYDRAULIC FLUID SPILL INSIDE THE |
| OWNER CONTROLLER AREA |
| |
| 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. |

| INITIATION OF A TECHNICAL SPECIFICATION (TS) REQUIRED SHUTDOWN DUE TO BOTH |
| TRAINS OF THE CONTROL ROOM VENTILATION SYSTEM BEING DECLARED INOPERABLE |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "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 temperature in the shared Unit 1 and 2 Control Room is currently 75�F. |
| Actions have been taken to restore service water to one of the chillers. |
| One chiller is currently in operation but [has] not yet been declared |
| operable." |
| |
| 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. |
| |
| The licensee notified the NRC resident inspector. |
| |
| ***** UPDATE AT 1609 ON 12/19/00 FROM RANDY TODD TO LEIGH TROCINE ***** |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "At 1455 on 12/19/00, Oconee Nuclear Station reported initiation of a |
| shutdown required by [TS] 3.7.16 which invokes TS 3.0.3. The TS affected |
| both Units 2 and 3." |
| |
| "This shutdown was due to loss of both chillers associated with the chilled |
| water system that serves the |
| Control Room Ventilation System. Units 2 and 3 began reducing power from |
| 100% in Mode 1 at 1452 (not |
| 1352 as initially reported)." |
| |
| "Following the initial notification, the NRC residents were informed." |
| |
| "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%." |
| |
| "An investigation into the cause of the chiller trips is continuing." |
| |
| "Unit 1 was in Mode 6 for a refueling outage and was not in the mode of |
| applicability for TS 3.7.16." |
| |
| The licensee stated that power ascension was commenced at 1521 and that the |
| Units 2 and 3 are currently operating at 100% power. |
| |
| The NRC operations officer notified the R2DO (Mike Ernstes). |

| UNPLANNED CLOSURE OF STEAM GENERATOR BLOWDOWN ISOLATION VALVES DURING |
| FUNCTIONAL TESTING OF A STEAM GENERATOR BLOWDOWN TANK LEVEL CONTROL VALVE |
| AND ITS ASSOCIATED SOLENOID VALVE |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "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. |
| |
| The licensee notified the NRC resident inspector. |
