| 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. |

| |
| The reactor automatically tripped from 100% power when the main turbine |

| MEDICAL MISADMINISTRATION |
| |
| On 10/27/1999, a patient was to receive a dose of 120 Gy (12,000 rad) by way |
| of implanted palladium seeds. The seeds that were ordered and delivered to |
| the hospital each had an activity of 1.05 millicuries each, instead of 1.4 |
| millicuries, which would have been needed to obtain the prescribed dose. The |
| physicians treating the patient made a decision to implant the seeds anyway, |
| resulting in a dose of 90 Gy, and to supplement the dose by external beam. |
| However, the written prescription kept in the hot lab was not annotated to |
| include this change in treatment. |
| |
| Therefore, this condition is being reported as a medical misadministration, |
| in that the actual dose was 25% less than that prescribed. The licensee |
| will contact the NRC Region III office regarding this issue. |

| GENERATOR TRIP - REACTOR SCRAM |
| |
| On October 29, 1999, at 1255 with the plant at 100% reactor power and in |
| Mode 1, a generator trip followed by a reactor scram occurred at River Bend |
| Station. The plant responded as expected, except that recirculation pump |
| 'A' failed to downshift to slow speed and tripped to off. The plant is |
| stable, and currently in Mode 3. Hot -Shutdown. Plant personnel continue |
| with an orderly shutdown. Work activities were in progress in the |
| switchyard at the time of the event. These activities are included in an |
| investigation of the cause of the event. |
| |
| The licensee notified the NRC resident inspector. |

| 24 HOUR 91-01 BULLETIN |
| |
| On 10/29/99 at 1040 hours, the Plant Shift Superintendent (PSS) was notified |
| that Procedure XP2-GP-MM2000, Rev. 1, "Operation of the Negative Air |
| Machine" was activated and used prior to the implementation of Nuclear |
| Criticality Safety Approval (NCSA) PLANT068.A01. Procedure (XP2-GP-MM2000, |
| Rev. 0) was revised (Rev. 1) and implemented on 9/1/99. This revised |
| procedure contained the flowdown requirements from the new |
| revision or the NCSA, without the NCSA being implemented. Several |
| requirements of the original NCSA were removed in the revision process, |
| including the requirement to have a second, knowledgeable person VERIFY that |
| the Negative Air Machine (NAM) is only used on equipment containing 5.25% |
| U235 enrichment or less. |
| |
| Since personnel operating the NAM were utilizing the newly revised |
| procedure, which reflects the requirements of the revised NCSA, they failed |
| to complete the requirement for the second person verification. This lack of |
| verification is deemed to be the loss of one control because the governing |
| NCSA (Rev.0) still lists this verification as a requirement. |
| |
| The Negative Air Machine was immediately tagged out of service, Procedure |
| XP2-GP-MM2000, Rev. 1 was placed on hold, and the previously approved |
| procedure was reactivated until NCSA PLANT068A01 is activated. This |
| Criticality Safety Incident is a Level 3 Severity Index (Loss of controls |
| such that only one double contingency control remains in place). |
| |
| SAFETY SIGNIFICANCE |
| |
| The safety significance, or this event is very low. The lack of documented |
| verification of enrichment for the Negative Air Machine since 9/10/99 did |
| not result in a loss of the enrichment parameter. Virtually all of the |
| equipment in X-333 is operated below 5.25% assay. A review of equipment |
| worked on with the NAM was performed and none of the equipment worked on had |
| been operated above 5.25% U-235 enrichment in the time period of interest. |
| |
| POTENTIAL CRITICALITY PATHWAYS |
| |
| The components of the negative air machine are not favorable geometry for |
| all enrichments. Current approved analysis limits uranium to 5.25%. however |
| a revised analysis which has been PORC approved has shown that an enrichment |
| up to 20% U-235 is safe in the Negative Air Machine. Therefore, an |
| enrichment above 20% would have to be present for a criticality to be |
| possible. However, this is extremely unlikely In the X-333 Facility. |
| |
| CONTROLLED PARAMETERS |
| |
| Enrichment is controlled with a first check arid a second verification. |
| Interaction Is controlled and mass is inherently controlled through the |
| physical limits of the filtration system to tolerate significant plugging. |
| Neither mass nor interaction were violated in this event. |
| |
| ESTIMATED AMOUNT, ENRICHMENT |
| |
| The filter units at PORTS typically contain less than 10 grams U-235 (<1.5% |
| critical mass). Since the negative air machine is used primarily to protect |
| personnel from hydrogen fluoride fumes, no significant mass of U-235 is |
| expected in the equipment. Due to the enrichment limits on the cascade |
| equipment In the X-333, enrichment is not expected to exceed 5%. |
| |
| NUCLEAR CRITICALITY SAFETY CONTROLS |
| |
| The control on this system included a first and second check to ensure the |
| enrichment limit was not violated for the negative air machine. The |
| requirement to perform the second check was removed from the procedure |
| without implementing a new analysis to support its removal. The second check |
| was not performed on over 15 maintenance jobs. |
| |
| CORRECTIVE ACTION |
| |
| At the direction of the Plant Shift Superintendent, the Negative Air Machine |
| was immediately tagged out of service and the procedure was placed on hold. |
| |
| THERE WAS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR |
| RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS THE RESULT OF THIS |
| EVENT. |
| |
| THE NRC RESIDENT INSPECTOR WAS NOTIFIED. THE DOE REPRESENTATIVE WILL BE |
| NOTIFIED. |

| |
| The Station Vent Stack Wide Range Gaseous Monitor is deenergized for planned |

| Repairs have been made to the pre-planned alternate (PING) and functional |
| testing has been completed as of 1527 CST. The PING was declared operable |
| at that time. Normal sampling of the Station Vent Stack has been resumed |

| TWO DIESEL GENERATORS INOPERABLE DURING TESTING |
| |
| During performance of the monthly testing of the #3 Emergency Diesel |
| Generator (EDG), the voltage regulator (control power) would not adjust |
| incoming voltage lower than 120 volts. The diesel was declared inoperable |
| pending further troubleshooting of the voltage regulator. |
| |
| As required by Surry Technical Specifications, the #1 EDG and the #2 EDG |
| were scheduled for operability testing on a daily basis. The #1 EDG was |
| inoperable from 2024 hours to 2203 hours for required testing which rendered |
| inoperable both EDGs for Unit 1. The #1 EDG was available at all times |
| during testing, however, it would have required operator action to load on |
| the bus. |
| |
| This report is being made pursuant 10CFR50.72(b)(2)(iii)(A) & (D) for a |
| condition that alone could have prevented the fulfillment of safety |
| structures or systems needed to shut down the reactor and maintain it in a |
| safe condition and mitigate the consequences of an accident. |
| |
| The licensee will notify the NRC resident inspector. |
