| 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.                                     |
|                                                                              |

| 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).                                                                        |
