| HIGH PRESSURE COOLANT INJECTION (HPCI) INOPERABLE |
| |
| 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. |
| |
| Repair efforts are in progress. |
| |
| The licensee informed the NRC resident inspector. |
| |
| ******************** UPDATE AT 1505 ON 02/04/99 FROM RON SERDA TO TROCINE |
| ******************** |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "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. |
| |
| "Therefore, [the] event notification of January 20, 1999, is retracted." |
| |
| The licensee notified the NRC resident inspector. The NRC operations |
| officer notified the R3DO (Kozak). |

| - LICENSEE DISCOVERED DUST FILTERS INSTALLED ON CONTAINMENT UNIT COOLERS - |
| |
| 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. |
| |
| THE LICENSEE IS REPORTING THIS CONDITION AS A CONDITION ALONE THAT COULD |
| PREVENT THE FULFILLMENT OF A SAFETY FUNCTION. |
| |
| AT 1714 CST ON 02/04/99, PLANT TECHNICIANS REMOVED THESE DUST FILTERS. THE |
| LICENSEE IS COMPLETING AN ENGINEERING ANALYSIS OF THE ABILITY OF THESE |
| COOLERS TO PERFORM THEIR SAFETY FUNCTION. |
| |
| THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR. |
