| HIGH PRESSURE COOLANT INJECTION SYSTEM (HPCI) DECLARED INOPERABLE |
| |
| "During normal monitoring of the standby lineup of the High Pressure Coolant |
| Injection System (HPCI), the building rounds operator noticed that the HPCI |
| discharge flow switch (23FS-78) was indicating 140 gpm with zero actual |
| flow. This flow switch controls the operation of the HPCI pump minimum flow |
| valve during HPCI operations. Upon further investigation by the operating |
| crew, it was also determined that the HPCI pump discharge flow transmitter |
| was exhibiting sporadic flow spikes of 50 to 100 gpm with zero system flow. |
| This flow signal is used to control HPCI turbine speed and flowrate. Based |
| on these findings, the HPCI system was declared inoperable per Technical |
| Specification 3.5.c and a 7 day Limiting Condition for Operation was |
| entered." |
| |
| The licensee called in an engineering team to address this problem. The |
| licensee will inform the NRC resident inspector. |
| |
| * * * RETRACTION 1529 4/18/01 FROM PAGE TAKEN BY STRANSKY * * * |
| |
| "On 2/19/01 at 0300 EST, the James A. Fitzpatrick nuclear power plant |
| notified the NRC that the High Pressure Coolant injection (HPCI) System had |
| been declared inoperable due to indicated flow on a local discharge flow |
| switch indication and sporadic flow spikes on the pump discharge flow |
| transmitter while the system was in the standby lineup. The report was made |
| pursuant to 10CFR50.72(b)(3)(v)(D) under Event Notification number 37761. |
| |
| "Based upon further review, it has been determined that, despite the |
| problems noted, HPCI would have performed its safety function. The local |
| HPCI discharge flow switch indication has no safety-related function. The |
| associated safety-related switches operated within the prescribed setpoint |
| tolerances. The hydraulic and mechanical portions of the system cannot |
| respond to change as quickly as the electronic components, and therefore |
| were not affected by the higher frequency sporadic spiking on the pump |
| discharge flow transmitter. Maintenance was performed to address the |
| associated degraded conditions. |
| |
| "Based upon the ability of the HPCI System to perform its safety function, |
| the above notification is being retracted." |
| |
| The NRC resident inspector will be informed of this retraction. Notified |
| R1DO (Ruland). |

| BOTH EMERGENCY DIESEL GENERATORS DECLARED INOPERABLE |
| |
| "Both Division 1 and Division 2 standby diesel generators were declared |
| inoperable. This report is being made per 10CFR50.72(b)(3)(v)(A), in that |
| both standby diesels were in a condition such that they may not have been |
| able to fulfill their intended safety function. |
| |
| "The division 1 diesel generator was declared inoperable because both diesel |
| generator room exhaust fans were found rotating backwards. The division 2 |
| diesel generator was declared inoperable due to one exhaust fan rotating |
| backwards and the outside air temperature exceeding 72�F. The cause of the |
| fan blades' reverse rotation is under evaluation. Reverse fan blade |
| rotation may cause longer in-rush starting currents which could cause the |
| fan motors to trip. |
| |
| "With two diesel generators inoperable, the plant entered Technical |
| Specification 3.8.1, a 2-hour shutdown Action Statement. |
| |
| "Division 1 and 2 diesel room exhaust fans stopped rotating, and the outside |
| air temperature lowered to less than 72�F The Technical Specification Action |
| Statements were exited. Periodic monitoring of the fans has been established |
| to address reoccurrence of the condition." |
| |
| The NRC resident inspector has been informed of this event by the licensee. |
| |
| * * * RETRACTED AT 1400 EDT ON 4/18/01 BY THOMAS RESTUCCIO TO FANGIE JONES * |
| * * |
| |
| The licensee is retracting the event notification based on the following: |
| |
| "Event notification 37900 was written due to the inoperability of Division I |
| and II emergency diesel generators. The diesel generators were declared |
| inoperable due to the diesel generator room exhaust fans spinning backwards. |
| The issue was that under reverse rotation, starting currents may exceed trip |
| values rendering the exhaust fans inoperable and, as a result, causing the |
| diesel generators to be declared inoperable. |
| |
| "At the time of discovery it was identified that the diesel generator |
| exhaust fans for Division I and II were observed to be rotating backwards at |
| approximately 10-15 rpms. An engineering analysis performed by the licensee |
| has determined that the tans can be spinning backwards up to 235 rpm and |
| will start and operate normally if needed. There will be no adverse affect |
| on the fans operability to perform their design safety function." |
| |
| The licensee notified the NRC Resident Inspector. The R1DO (William Ruland) |
| was notified. |

| DISCOVERY OF REACTOR COOLANT SYSTEM PRESSURE BOUNDARY LEAKAGE POSSIBLY VIA A |
| CONTROL ROD DRIVE MECHANISM ASSEMBLY SEAL WELD |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "On 4/10/01, during the removal of mirror insulation from the reactor vessel |
| head while shut down, deposits of residual boric acid were found on the |
| periphery of the Reactor Pressure Vessel Head outside of the Control Rod |
| Drive Mechanism (CRDM) Shroud. Subsequent investigation, by visual |
| inspection of the area within the shroud, revealed additional amounts of |
| boric acid. The source of the leak, based on initial observation, appears |
| to be a CRDM assembly seal-weld leak about 18 inches above the vessel head |
| insulation. A leak from this location would constitute Reactor Coolant |
| System Pressure Boundary leakage. Initial inspection of the reactor vessel |
| head areas, in the vicinity of the boric acid deposits outside of the |
| shroud, revealed no damage to the reactor vessel head." |
| |
| The licensee notified the NRC resident inspector. |

| |
| On 4/10/01, during the removal of mirror insulation from the reactor vessel |
| head while shut down. |
| deposits of residual boric acid crystals were found on the periphery of the |
| Reactor Pressure Vessel |
| Head outside of the Control Rod Drive Mechanism (CRDM) shroud. Subsequent |
| inspection at CRDM canopy seal welds and the reactor vessel head in the |
| vicinity of the boric acid crystal deposits was conducted with the head off |
| the reactor vessel and the shroud and some mirror insulation removed. The |
| identified source of the observed boric acid crystals was two very small |
| locations on the canopy seal weld of CRDM No. 68 at location B10. |
| |
| Leakage through the canopy seal weld is not pressure boundary leakage as |
| described in the Technical Specifications and Bases. The structural |
| integrity of the CRDM housing is maintained by the threaded connection. |
| The canopy seal weld does not maintain the structural integrity of the |
| reactor coolant system. Therefore, the original notification made pursuant |
| to 10CFR 50.72(b)(3)(ii)(A) is retracted. |
| |
| The NRC Resident Inspector was notified. |
| |
| Reg 2 RDO(Landis) was notified. |

| VALID CONTAINMENT VENTILATION ISOLATION |
| |
| "While in Mode Undefined (core offloaded), Salem Unit 1 received a |
| Containment Ventilation Isolation signal due to elevated count rate on |
| 1R11A, the Containment Particulate Radiation Monitor. The 1R11A setpoint is |
| set two times background in accordance with Tech Spec 3.3.3.1 for Mode 6. |
| Background count rate prior to the CVI was 2100 cpm (counts per minute). The |
| alarm setpoint was 2980 cpm. |
| |
| "The observed count rate when the actuation occurred was 3300 cpm. |
| Maintenance activities in progress included the breech of 14SJ43, Cold Leg |
| Injection Check Valve. Elevated airborne activity was expected due to this |
| evolution and had been discussed by Control Room personnel. When 1R11A |
| exceeded its setpoint, all containment ventilation isolation valves closed |
| as designed. This actuation has not impacted the Unit 1 outage. |

| SAFE SHUTDOWN TRAIN ELECTRICAL SEPARATION NOT ADEQUATE |
| |
| "HNP is in mode one, 100% power and stable. HNP personnel have determined |
| during an engineering review that fuses intended to maintain safe shutdown |
| train separation in the event of a fire in the 'A' Switchgear room are not |
| capable of performing their intended function due to a design error. A fire |
| in one fire area could result in the inability to isolate a Pressurizer |
| Power Operated Relief Valve (PORV) and associated block valve. These fuses |
| were intended to protect against this condition by isolating the PORV Block |
| Valve circuit on an electrical short due to a fire. These fuses provide |
