| PARTIAL LOSS OF OFFSITE POWER (ONE OF THREE SOURCES) DUE TO A TRANSFORMER |
| LOCKOUT |
| |
| At 0038 CDT, the east bus (345 kV) was lost due to a lockout on the #7 |
| transformer. The loss of the east bus resulted in the loss of normal power |
| to the 'A' safeguards bus (4.16 kV). On loss of power to the #7 |
| transformer, a shutdown sequencer actuation occurred due to low power. |
| This caused the 'A' emergency diesel generator to automatically start and |
| load the bus. The following equipment also automatically started: 'A' |
| centrifugal charging pump, 'A' component cooling water pump, 'A' essential |
| service water pump, 'A' control room air conditioning unit, 'A' class 1E air |
| conditioning unit, 'A' motor-driven auxiliary feedwater pump, 'A' and 'C' |
| containment coolers, and the turbine-driven auxiliary feedwater pump. The |
| licensee stated that all systems functioned as required and that there was |
| nothing unusual or not understood. |
| |
| At 0058 CDT, the licensee reset the #7 transformer lockout, and the east bus |
| was restored to service at 0059 CDT. At 0244 CDT, the licensee re-energized |
| the #7 transformer (the normal power feed to the safeguards bus |
| transformer), and normal offsite power was restored to the 'A' emergency bus |
| at 0256 CDT. |
| |
| The transformer lockout was initially believed to be caused by a lightening |
| strike and was later determined to be caused by a raccoon. |
| |
| The licensee notified the NRC resident inspector. |

| THE PLANT HAS OPERATED OUTSIDE THE DESIGN BASIS IN THE PAST DURING STARTUP. |
| |
| ON 03/18/99, FRAMATOME (B&W) REQUESTED THE LICENSEE REVIEW A |
| PRESSURE-TEMPERATURE LIMIT ANALYSIS FOR OCONEE NUCLEAR STATION |
| APPLICABILITY. THE ANALYSIS WAS PERFORMED FOR ANOTHER B&W PLANT AND SHOWED |
| THAT PRESSURE INCREASES ARE LARGER WITH NITROGEN IN THE PRESSURIZER. THIS |
| RESULTED IN A REVISED SET OF LOW-TEMPERATURE OVERPRESSURE PROTECTION ( LTOP) |
| LIMITS FOR STEAM AND NITROGEN OPERATION AT THE OTHER PLANT. FRAMATOME WAS |
| NOT AWARE OF NITROGEN PRESENCE BEING CONSIDERED IN THE DETERMINATION OF LTOP |
| LIMITS. |
| |
| OPERATIONS WAS REQUESTED TO USE A DEDICATED LTOP OPERATOR, AS A CONSERVATIVE |
| MEASURE, IF LTOP APPLICABILITY EXISTED AND NITROGEN PRESSURE WAS IN THE |
| PRESSURIZER. THIS IS A COMPENSATORY MEASURE REQUIRED BY TECHNICAL |
| SPECIFICATION 3.4.12, CONDITION 'F.' |
| |
| THE LICENSEE HAS COMPLETED AN EVALUATION THAT CONCLUDED THAT NITROGEN |
| OVERPRESSURE DURING STARTUP COULD RESULT IN LESS THAN 10 MINUTES BEING |
| AVAILABLE FOR OPERATOR RESPONSE AFTER THE ALARM SETPOINT IS REACHED DURING |
| AN LTOP EVENT. SINCE OPERATOR RESPONSE TO AN ALARM IS ONE TRAIN OF THE |
| OCONEE LTOP SYSTEM, THIS MEANS THAT THIS TRAIN HAS BEEN INOPERABLE DURING |
| PORTIONS OF PAST STARTUPS. THE APPLICABLE TIME PERIODS ARE ASSUMED TO HAVE |
| EXCEEDED THE 4 HOURS ALLOWED BY TECHNICAL SPECIFICATION 3.4.12, CONDITION |
| 'F,' FOR IMPLEMENTING COMPENSATORY MEASURES. SINCE THE LTOP MITIGATION |
| SYSTEM WOULD NOT MEET THE SINGLE FAILURE CRITERION DURING THESE TIME |
| PERIODS, THIS CONDITION IS BEING REPORTED AS OPERATION OUTSIDE THE DESIGN |
| BASIS OF THE PLANT. |
| |
| LTOP REQUIREMENTS DO NOT APPLY DURING PLANT OPERATION IN THE RUN MODE, AND |
| THERE HAVE BEEN NO LTOP EVENTS DURING PLANT OPERATION WITH A NITROGEN |
| PRESSURE BUBBLE IN THE PRESSURIZER. THEREFORE, THIS IS NOT CONSIDERED TO |
| REPRESENT AN ACTUAL CHALLENGE TO THE HEALTH AND SAFETY OF THE PUBLIC. |
| |
| THE RESIDENT INSPECTOR WAS INFORMED. |

| THE FLORIDA BUREAU OF RADIATION CONTROL REPORTED A RADIOLOGICAL INCIDENT, |
| #FL99-066, WHICH OCCURRED AT THE CITRUS MEMORIAL HEALTH FOUNDATION, INC., |
| LOCATED IN INVERNESS, FLORIDA. |
| |
| SIX IMPLANTED I-125 SEEDS MEASURING 0.265 mCi EACH WERE REMOVED FROM A |
| PATIENT AT THE FACILITY. WHEN THE SEEDS WERE TO BE RETRIEVED FOR SHIPMENT |
| BACK TO THE MANUFACTURER, ONLY ONE COULD BE FOUND. A THOROUGH SURVEY OF THE |
| ROOM AND SEWER TRAPS FAILED TO LOCATE THE OTHER FIVE SEEDS. THE MISSING |
| MATERIAL WAS PROBABLY LOST IN THE SANITARY SEWER. A STATE INSPECTOR IS |
| INVESTIGATING THE INCIDENT. |
