| At 1413 on January 20, 1999, the E4150-F022, "HPCI turbine exhaust drain pot |
| stop/check valve," which drains to the suppression pool, failed to meet      |
| stroke time requirements (28.6 seconds versus <=27 seconds required).        |
|                                                                              |
| The valve was closed and locked per Technical Specifications 3.6.3, Primary  |
| Containment Isolation Valves, at 1600.   With the E4150-F022 valve closed,   |
| it has been determined that the HPCI system is inoperable.  This valve path  |
| provides a drain path for the drain pot during accident conditions.          |
|                                                                              |

| "On January 20, 1999, the HPCI turbine exhaust two-inch drain containment    |
| isolation valve E4150-F022 stroke tested at 28.6 seconds.  The Inservice     |
| Test (IST) Program acceptance criteria was 27 seconds.  IST requirements for |
| acceptance and possible repairs of the valve were evaluated.                 |
|                                                                              |
| "The valve's stroke acceptance time was evaluated by Engineering Functional  |
| Analysis (EFA) 99-11550.  The EFA concluded that [a] stroke time [of] 30     |
| seconds is acceptable, and therefore, 28.6 seconds is acceptable.  The HPCI  |
| system [limiting condition for operation] was exited on January 21, 1999,    |
| based on the results of the EFA and the subsequent IST Program Evaluation,   |
| 99-003.                                                                      |

| DURING A REVIEW OF NRC INFORMATION NOTICE #99-01 WHICH DESCRIBES THE         |
| POTENTIAL FAILURE OF HEPA FILTERS DURING ACCIDENT CONDITIONS, THE LICENSEE   |
| DISCOVERED DUST FILTERS INSTALLED ON CONTAINMENT UNIT COOLERS (#HVR-UCIA &   |
| B) WHICH MAY BE SUBJECT TO DEGRADATION UNDER ACCIDENT CONDITIONS.            |
|                                                                              |
| AT 1632 CST ON 02/04/99, THE LICENSEE CONSERVATIVELY DECLARED THE TWO SAFETY |
| RELATED UNIT COOLERS INOPERABLE SINCE AT THIS TIME REASONABLE ASSURANCE THAT |
| THESE CONTAINMENT UNIT COOLERS WILL PERFORM THEIR SAFETY FUNCTION HAS NOT    |
| BEEN ESTABLISHED.                                                            |
