EVENT TEXT

| MANUAL REACTOR SCRAM DUE TO A LOSS OF STATOR WATER COOLING |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "At 0350 on 12/6/01 with the reactor at 100%, a manual reactor scram was |
| inserted due to the loss of stator water cooling. All control rods fully |
| inserted into the core. While taking a stator water sample, the heat |
| exchanger vent line broke off the heat exchanger losing stator water from |
| the system. A reactor scram was inserted prior to an [imminent] turbine |
| generator trip." |
| |
| "Following the reactor scram, water level dropped to approximately 120". |
| Reactor water level is being maintained in the normal level band (197") with |
| feedwater/condensate. The following 'Level 3' isolations occurred as |
| expected:" |
| |
| "Group 4 - RHR Shutdown Cooling and Head Spray" |
| "Group 13 - Drywell Sumps" |
| "Group 15 - Traversing Incore Probe Systems" |
| |
| "All valves in [Groups] 4 and 15 were closed prior to the event. Group 13 |
| valves closed as designed. No ECCS systems initiated, and no SRVs lifted. |
| All Emergency Diesel Generators are operable." |
| |
| The licensee stated that the main steam isolation valves remained open and |
| that the main condenser is being used as the heat sink. Containment |
| parameters are normal, and the grid is stable. |
| |
| The licensee notified the NRC resident inspector. |

| DISCOVERY OF A SHALLOW MONITOR WELL IN EXCURSION FOR SULFATE |
| |
| At approximately 1430 CST on 12/05/01, the licensee received second |
| confirmation of well #SM723 being in excursion for sulfate. Sulfate was |
| discovered to be at a concentration of 68 mg/l which exceeded the upper |
| control limit of 65 mg/l. This excursion is believed to be naturally |
| occurring, and the licensee has submitted a license amendment request to |
| change the upper control limit. The licensee also plans to maintain an |
| increased monitoring frequency. The licensee stated that well #SM723 is |
| located within a controlled well field with a shallow aquifer and that there |
| was no adverse impact expected on individuals or the environment. |

| THE LICENSEE MADE AN OFFSITE NOTIFICATION TO THE MISSOURI PUBLIC SERVICE
|
| COMMISSION |
| |
| The following is a report to the Missouri Public Service Commission (MPSC) |
| to notify the them of a forced outage at the Callaway Nuclear Plant. This |
| notification is reportable under 4CSR240-20.080(3)(B) because the outage is |
| expected to last longer than 72 hours. |
| |
| At 2248 CST, December 3, 2001, Callaway Plant shut down to effect repairs on |
| the Main Generator. A leak had developed on a Main Generator cooling |
| system requiring repairs which could only be made with the unit off-line. |
| Initially, the Plant was expected to return to service within 72 hours, but |
| due to the complexity of the repairs, the unit is now expected to return to |
| service after the 72-hour deadline has expired. Expectations are to return |
| to service by December 7, 2001. |
| |
| The Licensee has informed the NRC Resident Inspector of the MPSC |
| notification. |

| not on shift assignment, nor had the individual performed on-shift |
| activities during the past year. The individual's site access has been |
| terminated. The NRC resident inspector has been informed of this event by |
| the licensee. |
