| BOTH PRIMARY CONTAINMENT HYDROGEN RECOMBINERS WERE DECLARED INOPERABLE. |
| |
| During operation of Unit 2 at 100% power, it has been determined that both |
| Primary Containment Hydrogen Recombiners for the Suppression Pool Chamber |
| are inoperable. The 'A' recombiner had previously been removed from service |
| for maintenance activities, when the station's 'B' Emergency Diesel |
| Generator was declared inoperable after the main control room received an |
| unexpected trip alarm on the diesel. The diesel failure is not reportable |
| due to three diesels remaining operable. However, Technical Specifications |
| require that the 'B' recombiner be declared inoperable if the 'A' recombiner |
| is inoperable. This failure requires a 8-hr ENS Notification under |
| 10CFR50.72(b)(3)(v)(D), loss of a safety function to mitigate the |
| consequences of an accident. The 'B' Emergency Diesel was declared |
| inoperable due to a failed relay. |
| |
| The NRC Resident Inspector was notified. |
| |
| Technical Specification 3.8.1, condition 'B,' required action b.2, states, |
| "Declare the required feature supported by the inoperable diesel generator |
| inoperable when the redundant required features are inoperable also." |

| PLANT DECLARED RCIC INOPERABLE. |
| |
| During a panel walkdown, it was discovered that the RCIC flow controller |
| setpoint pointer was indicating erratically. Therefore, the flow controller |
| was declared inoperable resulting in RCIC being declared inoperable. |
| Troubleshooting is currently being performed on the controller. This |

| NON-CFR REPORT INVOLVING A VALID ACTUATION OF A "Q" QUALITY CLASS SAFETY |
| SYSTEM |
| |
| "On 3/1/01 at 2217 hours, Facility Operations Personnel received an alarm |
| indicating that Cascade Automatic Data Processing (CADP) smoke head |
| 'SXE-2783', located inside the housing near the LAW (low assay withdrawal) |
| compressor 'AB', had actuated. Operations Personnel were taking actions to |
| secure the LAW Station at the time of this actuation. Operations Personnel |
| responded immediately to investigate the cause for the alarm. Upon arrival, |
| no source for the alarm could be identified[. The] smoke head reset at 2226 |
| hours. The PSS (plant shift superintendent) requested a firing plot for all |
| smokeheads in the immediate area be printed for this time frame. The firing |
| plots indicate that five (5) smokeheads did recognize activity however, the |
| activity was minimal and did not actuate any other smoke heads. The PSS |
| notified the Facility Operations Personnel of his findings and requested |
| they have the housing panels removed for internal investigation to identify |
| any evidence of out gassing. Upon completion of this investigation, it was |
| identified that a minor out gassing had occurred. With this information this |
| event is reportable due to the valid actuation of a 'Q' Quality Class Safety |
| System." |

| Operations personnel informed the NRC resident inspector. |

| TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO FAILURE OF TWO FEEDWATER |
| FLOW CHANNELS TO RESPOND DURING A PLANT STARTUP |
| |
| The following text is a portion of a facsimile and E-mail received from the |
| licensee: |
| |
| "While performing a plant startup two channels of feedwater flow on [the] B |
| Main Feed line failed to respond. Investigation showed that both |
| transmitter's output was too low to support operability. These transmitters |
| provide the feed flow signal that, in conjunction with low steam generator |
| water level, provide a reactor trip. At 0225, [Technical Specification] |
| 3.0.3 was entered, and power was reduced at 0250 to a nominal 11%." |
| |
| "We expect to complete calibration/repairs on at least one of the |
| transmitter loops prior to 0725. If at least one transmitter loop is not |
| repaired, we must be in Hot Shutdown by 0925." |
| |
| The licensee notified the NRC resident inspector. |

| VARIOUS SAFETY SYSTEM ACTUATIONS DURING A PLANNED SHUTDOWN |
| |
| "While performing a planned shutdown for maintenance, an automatic scram and |
| group isolations occurred due to low Reactor water level. |
| |
| "The sequence of events was as follows: Initial manual scram was inserted at |
| 09:42 CST to complete the shutdown as part of the plant shutdown procedure. |
| Following the initial manual scram, 'B' Reactor Feed Pump (RFP) tripped on |
| high water level. 'A' RFP was previously secured as part of the shutdown |
| procedure. For undetermined reasons, 'B' RFP was unable to be returned to |
| service. An attempt was made to start the 'A' RFP but efforts were stopped |
| due to high vibrations received on 'A' RFP. Reactor Core Isolation Cooling |
| (RCIC) was manually started to provide make up to the RPV [Reactor Pressure |
| Vessel]. The subsequent shrink due to the relatively cool water being added |
| caused water level to lower to the low level scram set point (level 3), and |
| at 10:28 CST an automatic scram initiated, together with Group 2 (Primary |
| Containment), Group 3 (Reactor Water Cleanup) and Group 6 (Secondary |
| Containment) isolations. The Scram and automatic isolations functioned as |
| designed, except Group 3 had been previously actuated due to high |
| Non-regenerative Heat Exchanger temperature while initiating blowdown to the |
| main condenser for level control. Level was restored to approximately 17 |
| inches above the low level scram set point and the scram was reset. RCIC |
| flow was lowered in anticipation of swell due to heating, and level again |
| lowered. A manual scram was inserted approximately 4 inches prior to the low |
| level scram set point. Level was recovered using RCIC, and, following |
| resetting of the scram, water level was restored to the normal level, RCIC |
| secured, and condensate system used to raise level to the shutdown level |
| band. Level is presently being maintained using the condensate system. |
| |
| "Investigation is on-going for the cause of being unable to restore 'B' RFP |
| to service following the high level trip, and the reason for the high |
| temperature isolation of RWCU [Reactor Water Cleanup]. |
| |
| "The Senior Resident Inspector has been notified." |
| |
| The licensee is making preparations to place the unit in cold shutdown in |
| the next 2-4 hours. |
