| 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. |
| |
| |
| * * * UPDATE ON 5/1/02 @ 0331 BY AHO TO GOULD * * * |
| |
| NOUE terminated at 0221CDT. Plant in mode 5 (cold shutdown) |
| |
| The NRC Resident Inspector will be notified. |
