| 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. |
| |
| "POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW |
| CRITICALITY COULD OCCUR): |
| |
| "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. |
| |
| "CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION, ETC): |
| |
| "The parameter which was violated during this upset was maintaining |
| geometry/volume controls regarding potential accumulation points available |
| on/in nearby inadvertent containers. |
| |
| "ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE OF CRITICAL MASS): |
| |
| "No uranium-bearing material was actually involved in the upset. |
| |
| "NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| "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 |
| administrative control in NCSA 0705_076. |
| |
| "CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED: |
| |
| "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 will |
| remain shutdown until NCS (Nuclear Criticality Safety) can assist in |
| determination of operability of that system and compliance with NCSA |
| 0705_076." |
| |
| The NRC resident inspector has been informed of this event. |
