| UNANALYZED CONDITION - SI MINIFLOW LINE VALVE INTERLOCK MIS-WIRED            |
|                                                                              |
| "In the analysis for certain design bases accidents, credit is taken for a   |
| recirculation mode of operation that ensures continued cooling to the        |
| reactor core following an injection mode. During the current Unit 1          |
| refueling outage, it was found that a safety injection (SI) miniflow line    |
| valve (1HV-8813) interlock was mis-wired. The interlock wiring should have   |
| allowed a second valve (1HV-8804B) to be opened during switchover from       |
| injection mode to recirculation mode once 1HV-8813 has been closed but would |
| not. This wiring error was subsequently corrected. 1HV-8804B is opened to    |
| provide a suction source from the discharge of the Train B residual heat     |
| removal (RHR) pump to the suction of the SI pumps. 1HV-8804B must open for   |
| recirculation to begin if the opposite train is unavailable. A review has    |
| found that this mis-wiring has existed since at least 1996.                  |
|                                                                              |
| "Based on preliminary evaluation, on 3-12-2002, at 0830 EST, we concluded    |
| that this may represent an unanalyzed condition that significantly degrades  |
| plant safety and is reportable per 10 CFR 50.72 (b)(3)(ii)(B). Further       |
| evaluation is being performed to determine the significance of the           |
| mis-wiring."                                                                 |

| "RETRACTION - Further review of the event reported on 03/12/02 via           |
| Notification #38761, and described [above], has concluded that it is not a   |

| retracted."                                                                  |
