| HIGH PRESSURE COOLANT INJECTION (HPCI) DECLARED INOPERABLE DURING |
| SURVEILLANCE TESTING DUE TO LOW LUBE OIL PRESSURES. |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "Unit 2 HPCI was secured and declared inoperable after being placed in |
| service for a regularly scheduled surveillance test. During performance of |
| the pump, valve, and flow test, a lube oil pressure alarm annunciated due to |
| low lube oil pressures in various points throughout the system. All other |
| parameters were normal, and the system was operating properly. HPCI was |
| then secured, and a normal shutdown of the system was achieved. No other |
| abnormalities were identified throughout the entire evolution. |
| Investigation continues as to the cause of the low lube oil pressure |
| alarm." |
| |
| The unit was placed in a 14-day technical specification limiting condition |
| for operation as a result of this issue. |
| |
| The licensee plans to notify the NRC resident inspector. |
| |
| *** RETRACTION OF EVENT ON 01/22/99 AT 1418 EST FROM TONKINSON TAKEN BY |
| MacKINNON *** |
| |
| During surveillance testing of the Unit 2 HPCI system on 12/27/98, a low oil |
| pressure alarm was received in the control room. Lube oil pressure was |
| observed to be below the recommended value on a local pressure gauge at one |
| location. The low oil pressure was on a section of piping that supplies |
| lube oil to the governor end bearing only. All other system parameters were |
| normal, and surveillance testing acceptance criteria were satisfied. The |
| system was declared inoperable at that time. |
| |
| The ball valve supplying lube oil to the affected portion of piping was |
| removed, cleaned, and re-installed. Other lube oil system inspections |
| occurred. The lube oil was analyzed, and there was no evidence of bearing |
| degradation. |
| |
| Subsequent engineering analysis, with support from the turbine and bearing |
| manufacturers, concluded that the as-found oil pressure was sufficient to |
| supply lube oil to the governor end bearing indefinitely. No bearing damage |
| would be expected with operation at the observed oil pressure. The as-found |
| condition would not adversely affect the capability of the HPCI system to |
| fulfill safety-related functions. The HPCI system, therefore, was not |
| inoperable due to as-found lube oil pressure condition. |
| |
| The NRC resident inspector was notified of this retraction by the licensee. |
| The R2DO (Costello) was notified by the NRC operations officer. |

| SINGLE FAILURE COULD PREVENT COMPLETE CONTAINMENT ISOLATION DURING VENTING |
| (Refer to event #35301 for a similar event on Unit 2.) |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "At approximately 0915 hours on January 22, 1999, it was determined that |
| during containment pressure relief, the containment isolation function could |
| not be completely achieved if there [was] a containment isolation signal, |
| coupled with the single failure of containment isolation valve VS-PCV-1190 |
| to close. This would occur since initiation of pressure relief results in |
| three-way valve PS-SOV-1280 (a one-inch valve with one-inch ports on the |
| weld channel supply line between VS-PCV-1190 and VS-PCV-1191) changing |
| position to isolate [the] weld channel and vent the line between the |
| containment isolation valves (VS-PCV-1190 and VS-PCV-1191) to atmosphere. |
| If a postulated event were to occur that resulted in a containment isolation |
| signal, VS-PCV-1190 must close before an interlock with PS-SOV-1280 would |
| allow that valve to change position and supply weld channel gas between the |
| containment isolation valves. Thus, during pressure relief, a single |
| failure of VS-PCV-1190 to close on a containment isolation signal could |
| result in a one-inch vent path. Immediate corrective action was taken to |
| administratively restrict containment pressure relief until corrective |
| action to assure containment integrity during containment pressure relief |
| can be established such as isolation using an installed weld channel manual |
| isolation valve. This is a condition that resulted, during past containment |
| pressure relief operations, in Indian Point 3 being outside the plant design |
| basis for containment isolation." |

| The NRC resident inspector has been informed of this notification by the |

| BORIC ACID SYSTEM PIPING MAY NOT BE MAINTAINED AT PROPER TEMPERATURE. |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "CA-P-1A/B discharge piping heat trace is not maintaining adequate |
| temperatures. FSAR sec 9.2.1.2 states, 'Further, all piping, pumps, and |
| valves associated with the boric acid mix tank and the reclaimed boric acid |
| storage tanks to transport boric acid solution from them to the makeup and |
| purification system are provided with redundant electrical heat tracing to |
| ensure that the boric acid solution will be maintained 10 [�]F or more above |
| its crystallization temperature. The electrical heat tracing is controlled |
| by the temperature of the external surface of the piping systems.' |
| Temperature readings on the surface of the pipe ranged between 97.4 [�]F and |
| 171 [�]F. The heat trace setpoints are 160 [�]F. Based on recent chemistry |
| samples as high as 17,400 ppm and the crystallization curve, Figure 1A in OP |
| 1104-47B, the required temperature to prevent crystallization would be 117 |
| [�]F. Adding 10 [�]F would require a minimum 127 [�]F for the boric acid |
| solution." |
| |
| "The heat trace requirement is to ensure the boron does not crystallize and |
| prevent flow to the makeup tank. Quarterly [in-service] testing is performed |
| for CA-P-1A/B (most recently in November 1998). Although the required |
| solution temperature may not be being maintained, testing has shown that |
| these lines are not blocked and are functioning." |
| |
| "Because the temperature of the boric acid solution within the subject |
| piping cannot be confirmed via direct measurement or analysis at this time |
| to be at or above 127 [�]F, this condition has been identified as being |
| potentially outside the design basis of the plant and was reported to the |
| NRC within 1 hour in accordance with the requirements of 10 CFR |
| 50.72(a)(2)(ii)." |
| |
| "The chemical addition system pumps are currently out of service due to |
| maintenance being performed on the system, unrelated to the heat tracing. |
| The system in-service test is planned to be performed when the system is |
| returned to service. The chemical addition system in-service test performed |
| last November found the system performed as required at that time." |
| |
| "An analysis is planned to be performed to determine if the temperature of |
| the boric acid solution within the chemical addition system piping is at or |
| above the specified temperature." |
| |
| "Plans are underway to install, if necessary, additional insulation and, if |
| necessary heat tracing, to ensure the fluid temperature is maintained at the |
| correct temperature." |
| |
| "The potential outside design basis condition has been documented in CAP |
| T1999-0052 via the GPU Nuclear, Appendix B, corrective action program." |
| |
| The NRC resident inspector was notified of this event by the licensee. |

| SINGLE FAILURE COULD PREVENT COMPLETE CONTAINMENT ISOLATION DURING VENTING. |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "At approximately 12:10 hours on January 22, 1999, it was determined that |
| during containment pressure relief, the containment isolation function could |
| not be completely achieved if there [was] a containment isolation signal, |
| coupled with the single failure of containment isolation valve PCV-1190 to |
| close. The potential for this to occur exists since initiation of pressure |
| relief results in three-way solenoid valve SOV-1280 (a one-inch valve with |
| ports on [the] weld channel supply line between PCV-1190 and PCV-1191) |
| changing position to isolate [the] weld channel and vent the line between |
| the containment isolation valves (PCV-1190 and PCV-1191) to atmosphere. If |

| a single failure of PCV-1190 to close on a containment isolation signal |
| could result in a one-inch vent path, which would be a monitored release |
| path and filtered by the [primary auxiliary building] exhaust system." |
| |
| "Immediate corrective action taken will administratively require the closure |
| of a manual valve ( PCV-1110-8) any time that PCV-1190 is in the open |
| position thereby precluding a pathway for [the] containment atmosphere to |
| communicate with the environment." |
| |
| This condition was discovered in response to an event reported by Indian |
| Point 3. (Refer to event #35298 for additional information.) The licensee |
| is continuing its evaluation to identify any other primary containment |
| isolation valves which may be affected. |

| FAILURE TO IMPLEMENT AN NCSA IN BUILDING X-326 BECAUSE THERE WAS NO |
| PROCEDURE FOR OPERATION OF CALIBRATION BUGGIES |
| |
| This event was reported per NRC Bulletin 91-01 as a 4-hour notification. |
| |
| The following text is a portion of a facsimile received from Portsmouth: |
| |
| "On 01/22/1999 at 0930 hours during the on-going plant-wide search for |
| abandoned equipment, three (3) calibration buggies (all of different design) |
| were discovered in the X-326 [process building] building which may meet the |
| fissile material limits. All three (3) buggies meet the requirements of |
| NCSA-Plant069; but the NCSA was not implemented in the X-326 building |
| because there was not a procedure for operation of the calibration buggies. |
| The identified equipment has had a boundary set up around them, and the |
| anomalous NCS condition report is complete." |
| |
| "Spacing and geometry of the components on the buggies were controlled such |
| that the requirements of Plant069 were met." |
| |
| "The calibration buggies found do not violate the requirements of |
| NCSA-Plant069. The problem was the failure to flow down the requirements of |
| the NCSA into a procedure for the operation of the buggies. The problem was |
| in the implementation of the NCSA. The NCSA states that it is for use in |
| building X-326, but [it] was never implemented in that building." |

| DISCOVERY THAT A FIRE INDUCED FAULT COULD IMPACT EQUIPMENT REQUIRED FOR SAFE |
| SHUTDOWN |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "On 01/21/99, at 1545 hours, an Engineering review determined that in the |
| event of a fire in Fire Area 64, 'Reactor Enclosure Cooling Water Equipment |
| Area,' a fire induced fault in the 480-VAC power cable to the 2B Reactor |
| Enclosure Cooling Water (RECW) pump motor could open the load center (LC) |
| breaker to its associated motor control center (MCC) which would impact |
| equipment required for safe shutdown in the event of a fire in that area. |
| At that time, it was believed that this situation could only occur if the 2B |
| RECW pump was operating at the time of the fire. The 2B RECW pump currently |
| is not operating. This condition is due to less than adequate circuit |
| breaker coordination which is limited to a small region on the time-current |
| coordination curve for the LC breaker and the MCC breaker. On 01/22/99, at |
| 1400 hours, further investigation revealed that fire-induced damage to an |
| auto-start pressure switch in the control circuit for the 2B RECW pump |
| located in the affected fire area could create a hot short that would cause |
| the pump to auto-start resulting in the identified impact on safe shutdown |
| equipment. This represents a condition that is outside the design basis of |
| the plant and is reportable as a 1-hour notification in accordance with |
| 10CFR50.72(b)(1)(ii)(B). This condition is also considered a noncompliance |
| with the Fire Protection Program as described in the Limerick Generating |
| Station (LGS) Updated Final Safety Analysis Report (UFSAR), Section |
| 9A.6.1.1, and is reportable as a violation of LGS, Unit 2, Operating License |
| Condition 2.C.(3), 'Fire Protection.' Accordingly, this notification is |
| also being made within 24 hours as required by LGS, Unit 2, Operating |
| License Condition 2.E. This condition has existed since June 22, 1989, the |
| date of issuance of the Low Power Operating License for LGS, Unit 2. This |
| condition does not effect the operability of the 2B RECW pump or the |
| affected MCC based on the application of single failure criterion which |
| limits an electrical failure to a single division of safety-related power. |
| A fire watch has been established in the affected fire area as an |
| appropriate compensatory measure." |
| |
| The licensee notified the NRC resident inspector. |

| TECHNICAL SPECIFICATION SHUTDOWN DUE TO WESTINGHOUSE BREAKER CONCERNS |
| |
| Due to 4160-Volt Westinghouse 50-DH-350 breaker concerns on the Unit 1 |
| reactor coolant pumps, Technical Specification 15.3.5.-2.14.b and Technical |
| Specification 15.3.5-2.16, items a and b, were entered, and this requires |
| Unit 1 to be in a Hot Shutdown condition within 8 hours from 1600 CST. The |
| licensee said that this concern was part of a Ginna event sent out for |
| Westinghouse review. The licensee believes there is a laminated plate in |
| the shoot of the breaker that has a varnish which is holding the laminated |
| plates on. At this point, there is a concern about the operability of the |
| breakers. The laminated plates have been found to degrade over time, and |
| these plates can slide down and prevent the breakers from opening/closing. |
| Reactor coolant pumps, main feedwater pumps, and the '1A05' emergency bus |
| have the Westinghouse 50-DH-350 breakers. |
| |
| The only emergency operating piece of equipment out of service is the 'P38A' |
| (motor-driven auxiliary feedwater pump), which is out if service for |
| repairs. It should be back in service within the next 2 hours. The |
| electrical grid is stable, and since Unit 2 is in a refueling outage, it is |
| not affected by the breaker problem. |
| |
| The NRC resident inspector was informed of this event by the licensee. |

| 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. |

| PRIMARY CONTAINMENT ISOLATIONS FOLLOWING A MANUAL REACTOR SCRAM FROM 25% |
| POWER DUE TO LOWERING TEMPERATURE IN THE BOTTOM HEAD REGION OF THE REACTOR |
| PRESSURE VESSEL DURING SINGLE REACTOR RECIRCULATION LOOP OPERATION |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "EVENT: On January 23, 1999, at 06:38, primary containment groups 2, 6, and |
| 8 isolations were received following a manual reactor scram. The reactor |
| scram was inserted on Unit 1 due to lowering temperature in the bottom head |
| region of the reactor pressure vessel during single reactor recirculation |
| loop operation. The cooldown was augmented by recirculation pump runback to |
| 28% demand (expected action at low power due to total feedwater flow) which |
| reduced circulation through the vessel. A technical specification shutdown |
| was not required due to bottom head temperature at the time of the reactor |
| scram. Following the manual reactor scram, reactor water level lowered to |
| 160 inches. This is below the Reactor Water Level Low Level One setpoint of |
| 166 inches. This is a normal level transient following a reactor scram and |
| was anticipated by the operating crew. Although these isolations were |
| anticipated by the operating crew, they were not explicitly discussed prior |
| to the reactor scram; therefore, this report is being made in accordance |
| with 10 CFR 50.72(b)(2)(ii). All required isolations occurred as a result |
| of the Reactor Water Level Low Level One initiation signal. Reactor water |
| level immediately swelled above the Low Level One setpoint. Group 2 |
| isolation valves include drywell equipment and floor drains, traversing |
| incore probe, residual heat removal (RHR) discharge isolation to radwaste, |
| and RHR process sampling valves. Group 6 isolation valves include |
| containment atmosphere control system and post-accident monitoring valves. |
| Group 8 isolation valves include RHR system shutdown cooling isolation |
| valves; these valves were closed prior to the isolation signal." |
| |
| "INITIAL SAFETY SIGNIFICANCE EVALUATION: Minimal. All systems responded as |
| designed from the Reactor Water Level Low Level One initiation signal." |
| |
| "CORRECTIVE ACTION(S): Isolations occurred as designed; no corrective |
| actions [are] required." |
| |
| The licensee stated that Technical Specification 3.4.9, Reactor Coolant |
| System Pressure and Temperature Limits - Normal Operation With the Core |
| Critical, specifies minimum temperatures while critical. If parameters go |
| outside these references limits, this technical specification requires the |
| parameters to be restored within 30 minutes. With temperature lowering in |
| the bottom head region, the licensee chose to manually scram the reactor to |
| restore the parameter before expiration of the 30-minute limiting condition |
| for operation. |
| |
| All rods fully inserted following the manual reactor scram. There were no |
| emergency core cooling actuations or safety injections, and none were |
| expected. None of the relief valves lifted. |
| |
| The unit is currently stable in Mode 3 (Hot Shutdown). Normal feedwater is |
| being used to supply water to the reactor vessel. The main steam isolation |
| valves are open, the turbine stop and control valves are closed, and the |
| condenser is available as a heat sink. All containment parameters appear to |
| be normal. Offsite power is available, and the emergency diesel generators |
| are operable if needed. |
| |
| NOTE: Prior to this event, the unit was operating at reduced power to |
| facilitate the performance of a recirculation |
| pump motor-generator set brush replacement. |
| |
| The licensee notified the NRC resident inspector. |

| DURING POWER REDUCTION, THE REACTOR WAS MANUALLY TRIPPED DUE TO LOW |
| CONDENSER VACUUM. |
| |
| Prior to this event, one of four condenser waterbox sections was removed |
| from service for tube cleaning, and reactor power was increased from 90% to |
| approximately 92% power. At 0916 EST, a low condenser vacuum alarm was |
| received at which time the licensee commenced a power reduction. During |
| power reduction, condenser parameters continued to degrade due to |
| circulating water system air intrusion from a leaking isolation valve. The |
| reactor was manually tripped from approximately 73% power due to the |
| degradation of the condenser system. All rods fully inserted into the |
| reactor core, and all systems operated as expected. Both the motor-driven |
| and turbine-driven auxiliary feedwater pumps automatically started on |
| low-low steam generator water level. None of the power-operated relief |
| valves on the primary or secondary side of the plant opened. Decay heat |
| from the primary system of the plant is being dumped to the main condenser. |
| (The main condenser can handle the decay heat loads.) Both the motor-driven |
| and turbine-driven feedwater pumps were secured after main feedwater was |
| restored to service. The electrical grid is stable, and all the emergency |
| core cooling systems are fully operable is needed. |
| |
| The NRC resident inspector was notified of this event by the licensee. |
