| PLANNED MANUAL REACTOR SCRAM TO REPAIR A REACTOR RECIRCULATION PUMP FLOW |
| CONTROL VALVE |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "Grand Gulf Nuclear Station manually scrammed from 27% [core thermal power] |
| in preparation to repair reactor recirculation pump 'A' flow control valve |
| B33F060A. All control rods fully inserted, and all other safety systems |
| responded as designed. Condensate booster pump 'A' tripped for no apparent |
| reason. Investigation into why the 'A' condensate booster pump tripped is |
| underway." |
| |
| The licensee notified the NRC resident inspector. |
| |

| |
| The licensee is retracting this event notification. After further review, |
| the licensee determined that the manual reactor scram was part of a |
| pre-planned sequence of events and as such was not reportable under 10 CFR |
| 50.72(b)(3)(iv)(A). |
| |
| The licensee notified the NRC Resident Inspector. The R4DO (Gail Good) has |

| OFFSITE NOTIFICATION REGARDING A 30-GALLON DIESEL OIL SPILL FROM A FREIGHT |
| TRAIN WHICH DERAILED AND BREACHED THE PROTECTED AREA BOUNDARY |
| |
| A freight train derailed and breached the protected area boundary. There |
| were no personnel injuries as a result of this event. However, 30 gallons |
| of diesel oil spilled from the train. The oil was contained by trap rocks |
| and did not reach receiving waters. |
| |
| Security personnel have been posted as a result of the protected area |
| barrier breach, and fire protection personnel are currently on scene |
| cleaning up the diesel oil spill. The licensee is in the process of |
| notifying the Connecticut Department of Environmental Protection of the oil |
| spill. The licensee also requested that local police investigate the cause |
| of the train derailment. |
| |
| In addition to the initial 4-hour event report for the offsite notification, |
| the licensee plans to call back with an update to include the reporting |
| criterion for the breach in the protected area barrier. |
| |
| The licensee notified the NRC resident inspector and plans to notify |
| applicable state and local officials. |
| |
| ***** UPDATE FROM MIKE GOBELI TO LEIGH TROCINE AT 1115 ON 08/29/01 ***** |
| |
| The licensee provided this update to include an additional 1-hour security |
| reporting criterion to the initial 4-hour event report for the offsite |
| notification. The licensee determined that this event was also reportable |
| in accordance with 10 CFR 73.71(b)(1), Appendix G, I(1)(c), for a |
| degradation or discovered vulnerability in a safeguards system that could |
| allow unauthorized or undetected access to a protected area, controlled |
| access area, or vital area. |
| |
| The NRC operations officer notified the R1DO (David Lew), NRR EO (John |
| Tappert), IRO (Nader Mamish), NRR IAT (Richard Rosano), NMSS IAT (Aaron |
| Danis), Region 1 IAT (Greg Smith), Region 1 (Curtis Cowgill), Headquarters |
| OPA (Beth Hayden), and Region 1 OPA (Neil Sheehan). |

| DISCOVERY OF ABNORMALLY LOW ESSENTIAL SERVICE WATER FLOW TO EACH DIESEL |
| GENERATOR |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "This is Scott Richardson calling from the DC Cook Nuclear Plant with an |
| [8]-hour non-emergency notification in accordance with 10CFR50.72(b)(3)(v) |
| for 'Any event or condition that at the time of discovery could have |
| prevented the fulfillment of the safety function of structures or systems |
| that are needed to: (A) Shut down the reactor and maintain it in a safe |
| shutdown condition . . . . . . ' " |
| |
| "While performing an Essential Service Water (ESW) surveillance test on Unit |
| 2, it was noted that the ESW flow to each Diesel Generator was abnormally |
| low. This condition could have prevented the Diesel Generators from |
| fulfilling their safety function. This condition was caused by sand and |
| sediment in the ESW system and impacted both units." |
| |
| "Subsequent system flushes and valve cycling [have] eliminated the low flow |
| condition in both Unit 1 and 2 Diesel Generators." |
| |
| "We will continue to monitor ESW system performance. Further investigation |
| of this event is in progress to determine the root cause of the low flow |
| anomaly." |
| |
| "Unit 2 will be [shutting] down [and] going to [Cold Shutdown] beginning in |
| the next 3 hours." |
| |
| The licensee plans to notify the NRC resident inspector. |
