| AGREEMENT STATE REPORT - STOLEN GAUGE |
| |
| "On September 11, 2000, Fuller, Mossbarger, Scot and May Engineers, Inc., |
| reported a stolen moisture/density gauge. The gauge was a Troxler 3440, |
| serial number 24606, containing an 8 millicurie cesium-137 and a 40 |
| millicurie americium-241 source. |
| |
| "The gauge was stolen sometime between 12:00 am. and 6:00 a.m. on September |
| 11 from an employee's residence located in Lexington, KY. The police have |
| been notified. The employee had stored the gauge, in its transport |
| container, in his garage. He put the gauge, in its transport container in |
| the bed of his truck at about midnight in order to be ready to leave for the |
| job Site the next morning. One of the owners of the company stated that the |
| container was locked to the bed of the truck with a chain and padlock. The |
| thief used a hacksaw to cut the chain and remove the transport container |
| with the gauge inside. |
| |
| "The owner stated he believed the source rod to also be locked and that the |
| employee would have still have the keys to this lock." |
| |
| * * * UPDATE 1133 9/18/2000 FROM VICKI JEFFS VIA FACSIMILE * * * |
| |
| "The gauge, Troxler 3440, S/N 24606, was found, undamaged, on the side of |
| the road. The licensee now has possession of it. Licensee was cited for |
| improper gauge storage." |

| BOTH TRAINS OF RHR (RECIRC CAPABILITY) INOPERABLE FOR APPROXIMATELY SEVEN |
| HOURS |
| |
| "While placing RHR Train'B' in shutdown cooling during a refueling outage |
| the pump minimum flow valve did not close as expected. Investigation |
| revealed that the mini-flow transmitter 1 FIS-0611 was isolated causing the |
| valve 1 FV0611 to remain open with RHR flow in excess of setpoint that would |
| cause the valve to close. Work was performed on August 29, 2000, to |
| calibrate this transmitter. On September 9, 2000, RHR Train 'A' seal |
| cooler was isolated for maintenance rendering both trains of RHR inoperable |
| for 6 hours and 54 minutes. The Cold leg injection capability from RHR |
| Train 'A' remained available during this time. The Cold leg recirculation |
| capability during these inoperabilities was not available. This would have |
| required entry into T. S. 3.0.3. |
| |
| "RHR Train 'B' mini-flow transmitter 1FIS-0611 was discovered isolated |
| causing the valve 1FV0611 to remain open with RHR flow in excess of setpoint |
| that would cause the valve to close. The transmitter has been returned to |

| at 2236 psig, Tavg at 541F. Power as indicated on intermediate range |
| channels N35 & N36 was 4 x10 minus 12 amps and 7.5 x 10 minus 11 amps, |
| respectively. Control room operator was in the process of driving control |
| rods to 5 steps on Bank A, when P-6 permissive reset. Coincident with P-6 |
| reset, a control power fuse blew on IR channel N-36, causing a Rx trip from |
| 1/2 IR channels high. All rods fully inserted on the trip. Cause of the |
| blown fuse is under investigation and plant shutdown will continue using |

| UNIT OUTSIDE DESIGN BASIS OF FIRE PROTECTION PROGRAM |
| |
| "During review of the plant Cable and Conduit List (CCL) database, it was |
| observed that six essential cables were not listed as requiring fire wrap |
| and the cables are not wrapped in the field. The cable, with one exception, |
| is listed in the safe shutdown analysis as required for hot and cold safe |
| shutdown, but are not provided with Appendix R separation per 10CFR50 |
| Appendix R Section IIIG. The cables are located in Room 299 on the +46 ft |
| elevation of the Reactor Auxiliary Bldg (RAB) in Fire Area RAB 2. The |
| condition has existed since plant original construction. At the time of |
| discovery, the plant is operating at 100% Reactor Power. The cables were |
| immediately listed as impaired, and compensatory actions were established |
| (hourly fire watches). The condition has been entered into the plant |
| corrective action program (CR-WF3-2000-1088). The equipment would be |
| affected by a hypothetical fire in that fire area include the A/B Essential |
| Chillers, RAB HVAG Exhaust Fan A, RAB HVAC Equipment Room Supply Fan AH-13 |
| (3A-SA) Dampers. These components should be the protected components in the |
| fire area. The condition affects the ability to achieve safe shutdown. |
| Therefore, the condition is considered to be outside the design basis of the |
| fire protection program." |

| MAIN GENERATOR PARTIAL LOAD REJECT MAY NOT CAUSE REACTOR SCRAM AS ASSUMED |
| |
| "During evaluation of the data from a recent Reactor scram (Event #37325 on |
| 9/15/00) a possible unanalyzed condition was found. Specifically, a Main |
| Generator partial Load Reject can actuate a circuit contained in the turbine |
| controls that may not always activate a reactor scram/recirculation pump |
| down shift as required by analysis. Theoretically, with the partial load |
| reject that fails to actuate the Reactor Scram/Recirculation pump trip and |
| assuming failure of the bypass valves, MCPR limits could be affected. |
| Immediate corrective action is to change the setpoint of the EHC trip to |
| ensure that a partial load reject will result in a scram and Recirculation |
| pump transfer to slow speed." |

| OPERATORS MANUALLY STARTED EMERGENCY CONTAINMENT AIR COOLERS |
| |
| "On September 17, 2000, at about 0620 PDT, 2-ME-201 (non-safety containment |
| normal chiller) tripped on low oil pressure. Operators began to start the |
| containment normal chiller 2-ME-202, but stopped when prestart checks |
| indicated low freon level. Because containment temperatures were slowly |
| increasing, plant operators placed the emergency containment cooler units in |
| service and started an additional containment dome air circulator. To |
| perform their ESF function, the containment emergency coolers automatically |
| actuate on safety injection actuation signal and on containment pressure, |
| but not on containment temperature. SCE considered that the emergency |
| coolers were not performing an ESF function during this occurrence, and a |
| report to the NRC was not required. |
| |
| "On September 18, 2000, at 1000 PDT, SCE determined that actuation of the |
| emergency cooler units could be considered to meet the clarification |
| provided in section 3.3.2 of NUREG-1022, Rev. 1. Therefore, SCE is |
| conservatively and voluntarily providing this report to the NRC. After |
| determining that 2-ME-202 was functional with an indicated low freon level, |
| plant operators started 2-ME-202 at about 0818 PDT, terminating this |
| occurrence. The emergency coolers and dome air circulators operated as |
| designed. At the time of this occurrence, both units 2 and 3 were operating |
| at about 100% power. Unit 1 remains permanently defueled." |

| ECCS PERFORMANCE POTENTIALLY IMPAIRED DUE TO VALVE CLOSURE DURING TESTING |
| |
| "During review of emergency core cooling system (ECCS) valve operability |
| test procedures, it was determined that, on one occasion in 1995 and again |
| in 1997, one safety injection (SI) system containment isolation valve (CIV) |
| was closed for valve operability testing with reactor power at or near 100%. |
| With a CIV closed, injection from the two SI pumps following a small break |
| loss of coolant accident (SBLOCA) would be directed to only two of the four |
| reactor coolant system loops. At this power level, the high head SI system |
| function of maintaining peak clad temperature (PCT) below 2200�F following a |
| SBLOCA may not be satisfied. The condition becomes worse if a single failure |
| is considered to affect one of the two SI pumps. Further evaluation of the |
