| CONTROL ROOM VENTILATION OUTSIDE DESIGN BASIS CALCULATION |
| |
| The Licensee made the following voluntary notification: "On December 31, |
| 1998, while the plant was in operation, it was determined that based upon a |
| review of a previous Nuclear Safety Evaluation (NSE-98-3-015), # 33 Safety |
| Injection (SI) pump seal leakage placed the Control Room Ventilation System |
| outside its system design basis calculation assumption for external |
| recirculation system leakage (approximately 0.7 gph). The Control Room |
| Ventilation System continues to remain operable as per an existing |
| Operability Determination (#98-16). The New York Power Authority is |
| currently evaluating repair options for this SI pump seal." |

| INOPERABLE ATMOSPHERIC RELIEF VALVES |
| |
| The Licensee made the following notification: |
| |
| "On December 31, I998, WCNOC concluded that due to inoperable local control |
| of Atmospheric Relief Valve (ARV), AB PV-2, LCO 3.7.1.6 was not met during |
| certain periods of time. WCNOC Technical Specifications states that at |
| least three ARVs shall be operable and with more than one inoperable, |
| restore to operable within 24 hours. In addition to Technical Specification |
| requirements, the USAR requires four ARVs to be operable to meet design |
| basis cooldown requirements. To ensure the USAR requirements are met, WCNOC |
| has implemented Operations Special Order #17 which is more restrictive than |
| T.S. 3.7.1.6 by one additional ARV for all cases. This variance will be |
| corrected when Improved Technical Specifications are implemented. During |
| the period when the local control was not available for AB PV-2 other ARVs |
| have been removed from service for longer than the 24 hour LCO time. |
| Therefore, design bases requirements for safe shut down could not have been |
| met in the event of a fire. |
| |
| "A local control modification was installed for two ARV to satisfy fire |
| protection criteria in response to Generic Letter 92-08. During maintenance |
| in June 1998, it appears that tubing, was re-installed incorrectly on the |
| local control for AB PV-2. This condition was discovered during normally |
| scheduled surveillance testing on December 30/31, 1998. Therefore, the |
| potential operability for exceeding the LCO, was from June through December |
| 1998. Engineering and Maintenance are continuing to evaluate this |
| condition. |
| |
| "Maintenance activities are ongoing at this time to correct the tubing |
| installation on AB PV-2. This work activity is expected to be completed by |
| end of the day. Until that time, WCGS has entered the appropriate LCO." |
| |
| The Licensee notified the NRC Resident Inspector. |

| REACTOR TRIP DURING CONTROL ROD DRIVE BREAKER TESTING |
| |
| At 1435 hours on December 31, 1998, Oconee Unit 3 reactor tripped from 100% |
| steady state operation. Control Rod Drive breaker testing was in progress |
| at the time of the reactor trip. The 3A Reactor Protective System (RPS) |
| channel was in bypass for the breaker testing. When the associated CRD |
| breaker was tripped from the 3A RPS cabinet, the remaining three RPS |
| channels actuated causing the reactor trip. All rods fully inserted and the |
| plant responded properly to the reactor trip. The Unit is presently stable |
| at hot shutdown in forced circulation cooling, main feedwater supplying the |
| steam generators, and heat is being removed through the turbine bypass |
| valves to the main condenser. The cause of the trip is unknown at this time |
| and under investigation. |
| |
| The Licensee notified the NRC Resident Inspector. |

| SAFETY RELATED PUMP ROOM TEMPERATURE LESS THAN DESIGN |
| |
| FSAR Table 10.9-1 specifies that intake structure design temperature is 60 |
| -105�F with an outdoor temperature of 21�F. The Licensee determined that |
| the intake structure temperature was below 60�F. Specifically, in safety |
| related pump rooms (Salt Service Water) the temperatures were: |
| |
| Pump rooms A &B - 57�F |
| Pump rooms D & E- 56�F |
| Pump room C - 52�F |
| |
| Engineering has done a preliminary review of design requirements for |
| safety-related equipment and has thus far shown that the equipment can |
| perform its design function down to 32�F. |
| |
| Actions are underway to install temporary heaters and align ventilation to |
| raise temperatures above 60�F. |
| |
| The Licensee intends to notify the NRC Resident Inspector. |

| At 1545 MST on 1/1/99, PVNGS Unit 1 was informed by the Maricopa County |
| Sheriff's Department that a routine Siren Interrogation Test failed for all |
| (39) offsite sirens in the emergency planning zone. Appropriate personnel |
| have been dispatched to troubleshoot and repair. Although the cause is |
| currently unknown, there are no adverse weather conditions in the vicinity. |
| Contingency procedures are in place to compensate for a failure of the |
| offsite siren system. |

| MANUAL REACTOR TRIP DUE TO TURBINE CONTROL SYSTEM MALFUNCTION |
| |
| The licensee reported that the turbine control system instantaneously |
| reduced turbine load from 1161 MWe to about 200 MWe for an unknown reason. |
| Multiple steam generator alarms were received, control rods began inserting, |
| and the steam dumps opened in response to the turbine load decrease. |
| Pressurizer relief valve PCV-455A opened momentarily due to the pressure |
| transient. The reactor was manually tripped, all rods fully inserted, and |
| the auxiliary feedwater pumps, both motor and steam turbine driven, started |
| and restored steam generator level in all steam generators. The unit is |
| stable in Mode 3, Hot Standby. All safety systems responded as expected and |
| restart will be evaluated after further investigation of the cause of the |
| event. |
| |
| The licensee notified the resident inspector. |
