| UNUSUAL EVENT AT ANO2 DUE TO BORON RESIDUE AT PRESSURIZER HEATER
SLEEVE N-2  |
|                                                                              |
| "On 4/30/02, while performing a planned Reactor Coolant System Integrity     |
| Inspection following the 2R15 refueling outage, with the Reactor Coolant     |
| System at normal operating temperature and pressure (Mode 3), an inspector   |
| discovered small traces of boric acid on pressurizer heater sleeve N-2.      |
| Based on the subsequent evaluation, pressurizer heater sleeve N-2 has been   |
| determined to have had pressure boundary leakage. No current leakage is      |
| detectable. The Unit 2 Tech Spec 3.4.6.2 does not allow operation in Modes   |
| 1-4 with any pressure boundary leakage. Therefore a plant cooldown is being  |
| initiated to place Unit 2 in Mode 5. Based on this criteria, the condition   |
| is reportable upon declaring a Notification of Unusual Event (EAL 2.1) and   |
| Degraded Condition which is reportable per 1OCFR50.72(b)(3)(ii)(A)".         |
|                                                                              |
| The NRC Resident Inspector was notified.                                     |
