| THREE SPRINKLER SYSTEMS DECLARED INOPERABLE DUE TO CORRODED HEADS (24-hour |
| report) |
| |
| "On 06/02/99 at 1630 CDT, the Plant Shift Superintendent (PSS) was notified |
| that numerous sprinkler heads were corroded, affecting 16 sprinkler systems |
| in C-337 and one system in C-333, such that the ability of the sprinklers to |
| flow sufficient water was called into question. Subsequently, these |
| sprinkler systems were declared inoperable, and TSR-required actions |
| establishing roving fire patrols were initiated. This deficiency was |
| detected during scheduled system inspections conducted by Fire Protection |
| personnel. Currently, functionality of the sprinkler heads has not been |
| fully evaluated by Fire Protection personnel, and the remaining cascade |
| buildings are currently being inspected, and if necessary, this report will |
| be updated to identify any additional areas. It has been determined that |
| this event is reportable under 10CFR76.120(c)(2) as an event in which |
| equipment is disabled or fails to function as designed." The NRC resident |
| inspector has been notified of this event. |
| |
| * * * UPDATE AT 1022 EDT ON 06/04/99 FROM CAGE TO TROCINE * * * |
| |
| "Two sprinkler heads on system D-1 in C-337 and two sprinkler heads on |
| system 27 in C-335 were identified to also be corroded. These were |
| identified to the PSS on 06/03/99 at 1600 CDT and 1601 CDT, respectively, |
| and determined to require an update to this report by the PSS. It has been |
| determined that this event is reportable under 10CFR76.120(c)(2) as an event |
| in which equipment is disabled or fails to function as designed." Paducah |
| personnel notified the NRC resident inspector of this update. The NRC |

| AC FUSES USED IN DC SYSTEMS |
| |
| A concern was raised during the Expanded System Readiness Reviews conducted |
| earlier this year at Cook regarding the use of AC fuses in DC systems. |
| Protection in the Cook 250 VDC system is through the use of Gould Type RF |
| and Bussman Type FRN fuses. These fuses are not rated for use at the voltage |
| levels that may be encountered in the Cook DC system. |
| |
| Testing of the Gould fuses was recently completed and that showed that the |
| fuses in the 0 to 60 amp range can fail in such a manner that adjacent |
| components, equipment or personnel could be subjected to adverse conditions. |
| Although they were not tested, Bussman has stated that their fuses will not |
| operate safely at DC voltages over 125 VDC. |
| |
| Although not evaluated in detail, Electrical Design Engineering has |
| concluded that postulated failure of a fuse to safely clear a fault or |
| overload in a safety related or non-safety related circuit could result in |
| damage to adjacent safety related circuits. In addition, fuses are used as |
| isolation points between non-safety related components and the safety |
| related DC power supply system. A concern exists that an initiating event - |
| HELB, seismic, LOCA - could simultaneously impact multiple non-safety |
| related components. Consequently, if the isolation fuse fails to clear due |
| to the voltage rating concern, or the slow response causes a coordination |
| concern, the loss of multiple DC system panels or of the entire train(s) of |
| the safety related DC system could be the result. |
| |
| Electrical Design Engineering is evaluating replacement of the fuses. |
| |
| Both units are currently shutdown and defueled. This issue will be resolved |
| prior to startup. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| HIGH PRESSURE COOLANT INJECTION (HPCI) SYSTEM DECLARED INOPERABLE |
| |
| At 1750 EDT on 10/27/99, the HPCI System was declared inoperable and a 7 day |
| limiting condition of operation was entered in accordance with Technical |
| Specification 3.5.c. HPCI System surveillance testing conducted at 0130 EDT |
| met applicable surveillance test acceptance criteria. A more detailed |
| review of HPCI System startup transient data obtained during this testing |
| identified potential problems with HPCI Turbine Speed Control. Evaluation of |
| this transient data established a reasonable doubt concerning HPCI System |
| operability under all design conditions. All other Emergency Core Cooling |
| Systems and the Emergency Diesel Generators are fully operable. Reactor |
| Core Isolation Cooling System is fully operable and the electrical grid is |
| stable. The "B" Reactor Feedwater Pump is out of service for a turning gear |
