| AUTOMATIC TURBINE TRIP/REACTOR TRIP DUE TO HIGH HIGH STEAM GENERATOR WATER |
| LEVEL |
| |
| "On 06/11/03, Unit 2 Reactor tripped via Turbine Trip due to high-high |
| Steam Generator level. All Control Rods fully inserted. Unit stable in |
| Mode 3 (Hot Standby). Auxiliary Feedwater system was manually started and |
| currently maintaining steam generator levels. Investigation is in progress |
| to determine initial cause for loss of feed to the 2A Steam Generator from |
| its associated low power feedwater regulating valve." |
| |
| |
| Coming out of a refueling outage reactor power was at 30% when it was |
| noticed that main feedwater regulating valves were oscillating. Reactor |
| power was reduced to 20% and the low power feedwater regulating valves were |
| placed in service so testing of the main feedwater regulating valves could |
| be performed. During testing of the main feedwater regulating valves at |
| approximately 22% reactor power low power feedwater flow to the 2A Steam |
| Generator ceased. The dual indications for the low power feedwater |
| regulating valve indicated that the valve was open but Steam Generator 2A |
| water level was decreasing. Since main feedwater regulating valve was being |
| tested the 100% bypass low power feedwater regulating valve was opened. |
| Steam Generator water level began to increase rapidly so the valve was |
| closed. 2A Steam Generator level began to decrease so the 100% bypass low |
| power feedwater regulating valve was reopened. This time 2A Steam Generator |
| water level increase above 88% narrow range which caused an automatic |
| turbine trip. Since reactor power was greater than 15% the reactor |
| automatically tripped due to the turbine trip. All rods fully inserted into |
| the core. Since the reactor core had very little decay heat the main steam |
| isolation valves were closed and both motor driven auxiliary feedwater pumps |
| were manually started. Motor Driven Auxiliary Feedwater Pumps and Steam |
| Generator PORVs operation is maintaining the plant in a Hot Standby |
| condition. All emergency core cooling systems are fully operable and the |
| emergency diesel generators are fully operable if needed. The electrical |
| grid is stable. The licensee believes that the stem of the low power |
| feedwater regulating valve separated from the valve which in turn caused the |
| valve to close while still having dual indication that the low power |
| feedwater valve was open. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| INABILITY TO ACTIVATE EMERGENCY SIRENS DUE TO EQUIPMENT FAILURE |
| |
| "On June 11, 2003 at 0810 hours, the control room was notified that all |
| Prompt Alert and Notification System (PANS) sirens were inoperable. All |
| necessary notifications to local towns and MEMA (Massachusetts Emergency |
| Management Agency) have been made. A backup plan (route altering) is in |
| place in the event of an emergency at Pilgrim station. It was determined |
| that one of the sirens was transmitting a continuous radio signal to the |
| remaining sirens, preventing actuation. The faulty siren was isolated from |
| the system at 1125 hours." |
| |
| The licensee informed both state and local agencies and the NRC resident |
| inspector. |
| |
| This condition involving a different siren in the system occurred on |
| 6/10/03. See EN #39912. |

| CONTROLLED PLANT TS SHUTDOWN DUE TO LOSS OF HVAC SYSTEM |
| |
| "On 6/11/03 at 12:17, the 'A' Control Structure Chiller tripped. The 'B' |
| Control Structure Chiller was already inoperable for maintenance on the 'B' |
| Chiller Fans. With the loss of Control Structure HVAC System the ability to |
| maintain temperatures in various spaces including Relay rooms, Control Room |
| Floor Cooling and Emergency Switchgear rooms was lost. Units 1 and 2 |
| entered [Technical Specifications] TS 3.0.3 and a controlled shutdown of |
| both units were commenced at 13:15. The 'A' Chiller was restarted at 12:47 |
| and cooling was reestablished to the required areas, however the 'A' chiller |
| is not considered operable at this time. The 'B' Chiller was placed in |
| service and was declared operable at 13:20 [and the controlled shutdown of |
| both units were terminated]." |
| |
| "This constitutes a Tech Spec required shutdown and requires a 4-hr ENS |
| notification in accordance with 10 CFR 50.72(b)(2)(i). The failure also |
| requires an 8-hr ENS notification in accordance with 10 CFR |
| 50.72(b)(3)(v)(A-D) due to the loss of a safety function." |
| |
| The licensee notified the NRC Resident Inspector. |

| INVALID ACTUATION AND VARIOUS SYSTEM ISOLATIONS DUE TO A FAILED RELAY |
| |
| "On May 22, 2003, at 0802 central time, while operating at 100 percent |
| power, Grand Gulf Nuclear Station experienced an invalid actuation of the |
| 'B' Containment, Drywell, and Auxiliary Building Isolation System. A failed |
| relay caused a fuse to blow which resulted in actuation of the isolation |
| logic for the 'B' Containment, Drywell, and Auxiliary Building Isolation |
| System. This event resulted in isolation of the Plant Service Water (PSW), |
| Plant Chilled Water (PCW), Drywell Chilled Water (DWCW), and Instrument Air |
| (IA) to the Auxiliary Building. The PSW isolation caused loss of Component |
| Cooling Water (CCW) in the Auxiliary Building and loss of Turbine Building |
| Cooling Water. Reactor power was reduced to approximately 50 percent as a |
| result of the loss of PSW." |

| MISSING OR LOST GAUGE CONTAINING A RADIOACTIVE SOURCE |
| |
| A Texas Nuclear Product pipe mounted fixed gauge device, model 5202, Series |
| SG, serial number B174 containing a Cesium 137 (Cs-137), 500 millicuries |
| source (assay date of November 1984) could not be located in storage. The |
| gauge was removed from a pipe on the evening of 1/28/03 by an independent |
| contractor who placed the gauge in a temporary storage on the morning of |
| 1/29/03 at the Buchanan Mine Preparation Plant located in Mavisdale, |
| Virginia. The gauge was closed and pad locked before it was placed in the |
| small building storage room. The independent contractor and the plant |
| foreman looked for the gauge on 6/2/03 and could not locate it. They |
| continued looking for the gauge until 6/4/02 when they declared that it was |
| missing. The licensee has no reason to believe that the gauge left the |
| property, is retracing the steps of the gauge movement and is interviewing |
| their employees in an attempt to locate the gauge. |

| TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO INOPERABLE CHILLERS |

| "At 1409 on 6/11/03, both Control Complex Chillers were declared inoperable. |
| The inoperability resulted in an entry into ITS 3.0.3 due to the inability |
| to comply with ITS 3.7.18. At 1505 CR-3 [Crystal River Unit 3] began a |
| power decrease in compliance with the actions of ITS 3.0.3. This is a |
| 4-hour reportable event as required by 10 CFR 50.72(b)(2)(i). |
| |
| "At 1618 on 6/11/03 the operating Control Complex Chiller was declared |
| Operable and the actions of ITS 3.0.3 were exited. The plant has been |
| returned to full power operation. |
| |
| "The safety significance of this event was small. The Control Complex |
| cooling safety function was available through the use of existing procedures |
| and available alternate cooling methods. At 1456, an available Control |
