| 24-HOUR NRC BULLETIN 91-01 REPORT                                            |
|                                                                              |
| "On 8/28/00 at 1529, during implementation of NCSA 0705_076 (Inadvertent     |
| Containers) a concern was raised about the maximum distance of spray from a  |
| leak from a pressurized pipe. Calculations were reevaluated and the          |
| corrected spray distance for the system in question resulted in a distance   |
| of 106 feet. This new distance for the system in question is greater than    |
| the original implementation distance of 15 feet, which the NCSA had          |
| previously predicted for the entire X-705. This is considered a loss of one  |
| control. The control considered lost is control #2 which states in part,     |
| 'When unattended all potential inadvertent containers shall be:              |
| -modified to prevent unsafe accumulation                                     |
| -covered to prevent the in-leakage of spilled materials                      |
| -oriented to prevent an unsafe accumulation                                  |
|                                                                              |
| "The PSS(Plant Shift Superintendent) directed the facility custodian to      |
| enter an anomalous condition. The system in question was previously shut     |
| down prior to recalculation of the spray distance. The same equipment        |
| remains shutdown until compliance with NCSA 0705_076 can be determined.      |
|                                                                              |
| "SAFETY SIGNIFICANCE OF EVENTS:                                              |

| "Safety significance is low. The resulting situation is conservatively being |
| identified as a violation of one control contained in NCSA 0705_076 which    |
| requires that all potential inadvertent containers utilized in the X-705 be  |
| modified, covered, or oriented to prevent an unsafe accumulation. However,   |
| since the system in question maintained its physical integrity and thus no   |
| uranium bearing material was involved the safety significance of this event  |
| is low.                                                                      |
|                                                                              |

| "If a sufficient amount of uranium bearing material had leaked, spilled,     |
| splashed from the micro filtration system and the resuming material          |
| accumulated on/in an inadvertent container, an unsafe geometry could have    |
| resulted. If the leaking solution had contained a sufficient amount of       |
| uranium, the resulting configuration could have been sufficient for a        |
| criticality to occur. it should be noted that the allowed safe geometry and  |
| volume limits established in NCSA 0705-076 are based on optimally moderated  |
| solution which contains uranium enriched to 100 wt% U235.                    |
|                                                                              |

| "No uranium-bearing material was actually involved in the upset.             |
|                                                                              |

| "NCSA 0705_076 takes credit for the physical integrity of systems which      |
| contain uranium bearing materials. NCSA 0705_076 also takes Credit that      |
| unsafe volume/geometry containers are either modified, covered or oriented   |
| while in areas where uranium bearing material can leak, spill or spray to    |
| prevent an unsafe configuration from resulting in the event of a leak. The   |
| administrative control #2 was not being followed for the new area identified |
| where uranium bearing materials can leak, spill or spray. The resulting      |
| situation is conservatively being identified as a violation of the           |
