| LATE NOTIFICATION ON REACTOR CORE ISOLATION COOLING (RCIC) BEING DECLARED |
| INOPERABLE ON 01/20/99 |
| |
| On 01/20/99 at 1730 EST, RCIC became inoperable as a result of two |
| inoperable primary containment isolation valves being closed to satisfy |
| Technical Specification 3.6.3. RCIC was declared inoperable per Technical |
| Specification 3.7.4 (14 days to restore to operable status). Initial |
| assessment conclude that an immediate report was not required. However, |
| upon additional review, it has been determined that a 4-hour report is |
| required in accordance with 10 CFR 50. 72(b)(2)(iii)(D). RCIC was restored |
| to operable status on 01/22/99 at 1142 EST. The technical specifications |
| mentioned above were exited at the time. During the time period RCIC was |
| out of service, all emergency core cooling systems were fully operable. |
| |
| The NRC resident inspector was notified of this event by the licensee. |
| |
| ******************** UPDATE AT 1631 ON 02/16/99 FROM ROY GREEN TO TROCINE |
| ******************** |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "... RCIC was declared inoperable when it was believed [that] the starter |
| coils for two RCIC containment isolation valves (CIVs) would not function |
| properly in a degraded voltage situation, and the CIVs were closed to comply |
| with technical specifications.. |
| |
| "Subsequent review has determined that since the event or condition was |
| associated with the containment isolation function only and [since] the |
| reporting criteria is concerned with RCIC injection, the event is not |
| reportable. The operator actions to close the CIVs in accordance with |
| technical specifications [do] not constitute an event or condition as |
| discussed in the NUREG guidance. Therefore, notification of the event is |
| retracted. Additionally, evaluation and testing has concluded that the |
| starter coils in question would have functioned under all design |
| conditions. |
| |
| The licensee notified the NRC resident inspector. The NRC operations |
| officer notified the R1DO (Trapp). |

| DISCOVERY THAT UNIT 1 FUELING WATER STORAGE TANK (FWST) CHANNEL 3 WAS NOT |
| PLACED IN BYPASS WITHIN 6 HOURS OF BECOMING INOPERABLE |
| |
| FWST Channel 3 was tripped shortly after 0800 today to facilitate a |
| modification to change out a transmitter. With this channel removed from |
| service, plant technical specifications require the licensee to place the |
| channel in bypass within 6 hours. At 2145, it was discovered that the |
| channel had not been placed in bypass within 6 hours of becoming inoperable, |
| and the unit entered Technical Specification 3.0.3. The channel was |
| successfully placed in bypass within 2 minutes, and Technical Specification |
| 3.0.3 was exited at 2147. |
| |
| The licensee plans to notify the NRC resident inspector. |

EVENT TEXT

| HISTORICAL MANUAL REACTOR TRIPS FROM MODE 3 (HOT STANDBY) DUE TO ROD GROUPS |
| MOVING OUT OF SEQUENCE DURING ROD DROP TESTING |
| |
| During a review of industry Licensee Event Reports, the licensee determined |
| that two historical manual reactor trips were reportable. This |
| determination was made at 1635 on 02/16/99. |
| |
| The events occurred on 10/13/90 for Unit 2 (Cycle 8) and 05/12/94 for Unit 1 |
| (Cycle 14) while both units were in Mode 3 (Hot Standby) in preparation for |
| exit refueling outages. On both occasions, the licensee was performing rod |
| drop testing. When operators began to pull out one of the control banks on |
| Unit 2 and one of the shutdown banks on Unit 1, one group moved prior to the |
| other (out of sequence). To alleviate this problem and to prevent the need |
| to realign individual rods, the licensee manually opened the reactor trip |
| breakers on both occasions. The historical engineering data did not |
| indicate any significant abnormalities. |
| |
| Both units are currently in Mode 5 (Cold Shutdown). |
| |
| The licensee notified the NRC resident inspector. |

| WAS BEING SUPPLIED FROM ITS RESERVE FEED AND THE LICENSEE DETERMINED IT TO |
| BE TRIPPED DUE TO A FAILED VOLTAGE REGULATOR. THE LICENSEE REENERGIZED THE |
| #2A RPS FROM ITS NORMAL FEED AND RESTORED THE PLANT LINEUP TO NORMAL EXCEPT |
| THE #2A MAIN STEAM LINE RADIATION MONITOR DOWNSCALE WOULD NOT RESET. THE |
| LICENSEE INSERTED A HALF SCRAM SIGNAL AND A HALF PCIS GROUP 1 ISOLATION |
| SIGNAL IN ACCORDANCE WITH TECH SPEC REQUIREMENTS WHILE REPAIRS ARE IN |
| PROGRESS. |
