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. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 37269 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: LIMERICK REGION: 1 |NOTIFICATION DATE: 08/29/2000| | UNIT: [] [2] [] STATE: PA |NOTIFICATION TIME: 06:37[EDT]| | RXTYPE: [1] GE-4,[2] GE-4 |EVENT DATE: 08/29/2000| +------------------------------------------------+EVENT TIME: 03:15[EDT]| | NRC NOTIFIED BY: CRAIG HOFFMAN |LAST UPDATE DATE: 08/29/2000| | HQ OPS OFFICER: BOB STRANSKY +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |PETE ESELGROTH R1 | |10 CFR SECTION: | | |AIND 50.72(b)(2)(iii)(D) ACCIDENT MITIGATION | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ | | | |2 N N 0 |0 | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | HPCI SYSTEM DECLARED INOPERABLE | | | | "While performing valve strokes for a normally scheduled High Pressure | | Coolant Injection (HPCI) surveillance test, the outboard suppression pool | | suction Primary Containment Isolation Valve (PCIV) to HPCI failed to stroke | | open.
