| "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   |

| "Two sprinkler heads on system D-1 in C-337 and two sprinkler heads on       |
| system 27 in C-335 were identified to also be corroded.  These were          |
| identified to the PSS on 06/03/99 at 1600 CDT and 1601 CDT, respectively,    |
| and determined to require an update to this report by the PSS.  It has been  |

| 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.                 |

| 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%.             |
|                                                                              |

| 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.                               |
|                                                                              |

| 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.  |
|                                                                              |

| 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.                         |
