| While investigating a previous Licensee Event Report concerned with backfeed |
| the following was discovered:                                                |
| "During a scenario involving a Loss of Off-Site Power resulting from a loss  |
| of the BEST and Startup transformers, the Crystal River Unit 3 abnormal      |
| operating procedures could have caused an overload of the safety-related     |
| Engineered Safeguards 4160V to 480V transformer.  Assuming a single failure  |
| of the 'B' side diesel generator, power could have been unavailable to both  |
| trains of 480V Engineered safeguards loads.  This condition is considered    |
| reportable per 10CFR50.72(b)(l)(ii)(B) and 10CFR50.73(a)(2)(ii)(B) as a      |
| condition outside of the design basis of the plant.  Loads have been         |
| identified which can be administratively maintained off during this scenario |
| to avoid the overload condition, and therefore, the transformer is           |
| operable."                                                                   |

| THIS OCCURRED WHEN AN ELECTRICIAN LIFTED A LEAD WHILE REPLACING RELAY        |
| "2-CLS-RLY-1B1" IN THE "B" TRAIN HIGH CLS SYSTEM.  ONE CONTAINMENT TRIP      |
| VALVE FOR THE CONTAINMENT PARTICULATE AND GAS RADIATION MONITORS             |
| REPOSITIONED (CLOSED), AND THE PARTICULATE AND GAS RADIATION MONITOR PUMP    |
| DE-ENERGIZED.   A SAFETY INJECTION SIGNAL WAS NOT RECEIVED AS IT WAS         |
| PROPERLY DEFEATED IN ACCORDANCE WITH STATION PROCEDURES.  THE ELECTRICIANS   |
| VERIFIED THAT THE HIGH CLS SYSTEM WAS DE-ENERGIZED AS THEY WOULD EXPECT      |
| PRIOR TO PERFORMING WORK TO PREVENT A SPURIOUS ACTUATION.  THE LICENSEE IS   |
| INVESTIGATING THE CAUSE AND THE REQUIRED CORRECTIVE ACTIONS.  THE HIGH CLS   |
| SIGNAL WAS RESET SINCE THE 2/4 CONTAINMENT PRESSURE < 14.2 PSIA MATRIX WAS   |
| MET DUE TO THE ACCURACY OF THE GAUGES.  THE TRIP VALVE WAS PLACED IN THE     |
| PRE-EVENT CONDITION (OPEN), AND THE RADIATION MONITOR PUMP WAS RE-ENERGIZED  |
| AND RESTARTED.  CORE OFF LOAD WAS NOT IN PROGRESS AT THE TIME OF THIS        |

| "At 1113 on April 26, 1999, a 4-hour Non-Emergency Notification was made in  |
| accordance with 10CFR50.72(b)(2)(ii) due to an ESF actuation.  An            |
| inadvertent Unit 2 High Consequence Limiting Safeguards (CLS) signal for     |
| Train 'B' was caused by maintenance activities when replacing a High CLS     |
| relay (#2-CLS-RLY-1B1) with Unit 2 in Refueling Shutdown.  The High CLS      |
| signal only initiated the closure of containment trip valve #2-RM-TV-200B,   |
| which caused the sample pump, #2-RM-P-200, for the containment particulate   |
| and gaseous radiation monitors to de-energize."                              |

| "NUREG-1022, Event Reporting Guidelines 10CFR50.72 and 50.73, states that    |
| 'The Commission is interested both in events where an ESF was needed to      |
| mitigate the consequences (whether or not the equipment performed properly)  |
| and events where an ESF actuated unnecessarily.... Usually, the staff would  |
| not consider this to include single component actuations because single      |
| components of complex systems, by themselves, usually do not mitigate the    |
| consequences of significant events.'"                                        |

| "Based on further review of this event and guidance provided in NUREG-1022,  |
| it was determined that this event was not reportable as the High CLS signal  |
| was invalid and resulted in the actuation of only one component which did    |
| not mitigate the consequences of the event."                                 |

| DISCOVERY OF A MISSING CHEMICAL AGENT MONITOR CONTAINING 15 mCi OF NICKEL-63 |
| FROM SHAW AIR FORCE BASE LOCATED IN SUMPTOR, SOUTH CAROLINA                  |
|                                                                              |
| At 0938 on 05/07/99, Shaw Air Force Base (AFB) located in Sumptor, South     |
| Carolina, notified the U.S. Air Force Radioisotope Committee located at      |
| Bolling AFB located in Washington D.C. of a missing chemical agent monitor   |
| (CAM) containing a 15-mCi nickel-63 source.                                  |
|                                                                              |
| On 04/27/99, the base radiation safety officer (RSO) at Shaw AFB conducted   |
| an inventory of CAMs located in building #1981.  The correct number of CAMs  |
| were there, but one had the wrong serial number.  Examination of previous    |
| inventories shows one CAM with a different serial number.  The building had  |
| been searched with no success.  The 20CES/CEX RSO has no explanation for the |
| different serial number on one CAM or where the correct CAM may be located.  |
|                                                                              |
|                                                                              |
| It is suspected that the CAM may have been exchanged with another Air Force  |
| Unit or may have been sent off for calibration.  At this time, the U.S. Air  |
| Force Radioisotope Committee believes that the CAM is still in Air Force     |
| possession.  Past shipping records will be researched, and calibration labs  |
| that serve Shaw AFB will be notified.  The completion time for these actions |
| is currently estimated to be 06/07/99.                                       |
|                                                                              |

| The licensee plans to notify the NRC Region 4 office and plans to issue a    |
| 30-day written report.                                                       |

| AUTOMATIC REACTOR SCRAM DUE TO LOSS OF EHC PRESSURE                          |

| An automatic reactor scram occurred due to high reactor vessel pressure      |
| (1080 psig) after the main turbine stop and control valves drifted closed.   |
| All control rods inserted following the scram, and all systems functioned as |
| expected.  Neither the HPCI nor RCIC systems started, as reactor vessel      |
| water level did not decrease to the automatic actuation setpoint.  The       |
| licensee reported that an operator inadvertently isolated the main turbine   |
| electrohydraulic control (EHC) system oil supply while tagging out the       |
| standby EHC oil pump, causing the turbine stop and control valves to drift   |
| closed.                                                                      |

| - 15,000 GALLON MINING INJECTION SOLUTION SPILL -                            |
|                                                                              |
| A WELLFIELD MINING INJECTION SOLUTION ("BARREN LIXIVIANT") SPILL OCCURRED AT |
| THE IN-SITU LEACH INJECTION MINE UNIT 5 (#5BD47-1) AT THE CHRISTENSEN MINE   |
| IN CAMPBELL COUNTY, WY.                                                      |
|                                                                              |
| THE SPILL, WHICH IS ESTIMATED TO BE 15,000 GALLONS WITH A URANIUM            |
| CONCENTRATION OF                                                             |
| 1.0 mg/I OF U3O8,  IS THE RESULT OF A PLUMBING FAILURE AT THE INJECTION WELL |
| HEAD.  THE SPILL WAS REPORTED TO THE NRC SINCE IT IS GREATER THAN 10,000     |
| GALLONS, WHICH IS CONSIDERED SIGNIFICANT FROM AN OPERATIONS STANDPOINT.      |
|                                                                              |
| THE SOLUTION SPILLED ONTO THE NEARBY SOIL AND IT IS ANTICIPATED THAT THE     |
| SPILL DOES NOT POSE A HEALTH OR ENVIRONMENTAL HAZARD DUE TO ITS LOW          |
| CONCENTRATION OF URANIUM.  THERE ARE NO RESIDENTS  WITHIN ONE MILE OF THE    |
| SPILL AND THE NEAREST TOWN IS FURTHER THAN 15 MILES AWAY.                    |
|                                                                              |
| THE INJECTION WELL WAS SHUT DOWN AND THE SPILL WAS STOPPED.  THE WELL WILL   |
| NOT BE USED UNTIL THE PLUMBING IS REPAIRED.  A SOIL SAMPLE HAS BEEN          |
| COLLECTED AT THE SPILL LOCATION AND WILL BE ANALYZED FOR THE PRESENCE OF     |
| Ra-226 TO DETERMINE IF SOIL CLEAN-UP IS NECESSARY.                           |
|                                                                              |

| AT 1645 ON 05/09/99, DURING A PRESSURE DECAY TEST OF THE #1 AUTOCLAVE IN THE |
| X-342 BUILDING, A LIGHT DUSTING OF UO2F2 WAS OBSERVED INSIDE THE AUTOCLAVE   |
| AND A HEAVIER ACCUMULATION OF UO2F2 WAS OBSERVED ON THE PRESSURE DECAY       |
| FILTER USED TO PREVENT URANIUM FROM ENTERING THE AUTOCLAVE DURING THIS TEST. |
| THE AUTOCLAVE WAS PLACED IN A CONTAINMENT MODE ISOLATING IT FROM ALL SUPPORT |
| SYSTEMS.  HEALTH PHYSICS TECHNICIANS PERFORMED CONTAMINATION AND AIRBORNE    |
| SAMPLING AND ALL SAMPLES WERE LESS THAN DETECTABLE LIMITS.  HAVING URANIUM   |
| INSIDE THE SHELL OF THE AUTOCLAVE IS A LOSS OF ONE CONTROL OF THE DOUBLE     |
| CONTINGENCY PRINCIPLE CONTAINED IN NCSA_342A002.  THE ACCUMULATION OF UO2F2  |
| ON THE OUTSIDE OF THE PRESSURE DECAY FILTER IS NOT EXPECTED.  ADDITIONAL     |
| EVALUATIONS ARE BEING CONDUCTED AT THIS TIME.                                |
|                                                                              |
| THERE IS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR                        |
| RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS A RESULT OF THIS EVENT.   |
| THIS EVENT DOES NOT PRESENT ANY IMMINENT DANGER OF A CRITICALITY.            |
|                                                                              |
| THE AUTOCLAVE HAS BEEN ISOLATED FROM ALL POTENTIAL MODERATOR SOURCES, SO     |
| CRITICALITY IS NOT POSSIBLE.  MODERATION, ENRICHMENT AND GEOMETRY PARAMETERS |
| WERE MAINTAINED THROUGHOUT THIS EVENT.  THE UNLIKELIHOOD OF URANIUM INSIDE   |
| THE AUTOCLAVE SHELL AND OUTSIDE OF THE UF6 CYLINDER WAS A LOST PARAMETER.    |
| THE AUTOCLAVE WAS TAGGED TO PREVENT ANY OPERATION UNTIL RECOVERY PLANS ARE   |
| DEVELOPED.                                                                   |
