| BOTH REACTOR RECIRCULATING SAMPLE LINE CONTAINMENT ISOLATION VALVES DECLARED |
| INOPERABLE |
| |
| During operation of Unit 2 at 100% power, it has been determined that both |
| Primary Containment Isolation Valves for the Reactor Recirculating Sample |
| Line are inoperable. During restoration from maintenance activities on the |
| line, the outboard isolation valve[HV243F020] failed to stroke closed. |
| Following several attempts the valve was closed. The valve was declared |
| inoperable, and as required by Technical Specifications an attempt was made |
| to close the inboard isolation valve[HV243F019]. The inboard valve also |
| failed to close. The air supply was isolated to the outboard valve to |
| deactivate it, and the pathway was confirmed to be isolated. The problem |
| with the outboard valve is due to a bad solenoid. The problem with the |
| inboard valve is under investigation. They were able to get both valves |
| closed when the inboard valve finally closed on its own an hour later. |
| |
| The NRC Resident Inspector was notified. |

| PLANT DECLARED SSPS(SOLID STATE PROTECTION SYSTEM) INOPERABLE |
| |
| Reactor shutdown was initiated at 1900 due to train "B" SSPS being declared |
| inoperable. Technical Specifications 3.3.1.1 and 3.3.2.1, which were |
| entered at 1628, requires the Unit to be in hot standby within 6 hours. |
| The problem was caused by a redundant power supply to the "B" train being |
| declared inoperable, and an incorrect procedure. Procedure changes are |
| currently being developed to correct it. |
| |
| The NRC Resident Inspector was notified. |
| |
| * * * UPDATE ON 2/8/01 BY JOHNSON TO GOULD * * * |
| |
| Procedural changes were complete at 2030 and power reduction was terminated |
| at 58% and power was stabilized between 50 and 55 percent. The plant will |
| maintain that power level until feed pump repairs are complete(approx. 4-5 |
| hrs). |
| |
| The NRC Resident Inspector was notified. |
| |
| The Reg 3 RDO(Clayton) and NRR EO(Marsh) were informed. |
