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. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |Power Reactor |Event Number: 36377 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | FACILITY: LASALLE REGION: 3 |NOTIFICATION DATE: 10/31/1999| | UNIT: [1] [2] [] STATE: IL |NOTIFICATION TIME: 14:00[EST]| | RXTYPE: [1] GE-5,[2] GE-5 |EVENT DATE: 10/31/1999| +------------------------------------------------+EVENT TIME: 12:03[CST]| | NRC NOTIFIED BY: SHANE MARIK |LAST UPDATE DATE: 10/31/1999| | HQ OPS OFFICER: DOUG WEAVER +-----------------------------+ +------------------------------------------------+PERSON ORGANIZATION | |EMERGENCY CLASS: N/A |MIKE JORDAN R3 | |10 CFR SECTION: | | |AARC 50.72(b)(1)(v) OTHER ASMT/COMM INOP | | | | | | | | | | | +-----+----------+-------+--------+-----------------+--------+-----------------+ |UNIT |SCRAM CODE|RX CRIT|INIT PWR| INIT RX MODE |CURR PWR| CURR RX MODE | +-----+----------+-------+--------+-----------------+--------+-----------------+ |1 N N 0 Refueling |0 Refueling | |2 N Y 100 Power Operation |100 Power Operation | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | Station Vent Stack Monitoring Inoperable. | | | | The Station Vent Stack Wide Range Gaseous Monitor is deenergized for planned | | maintenance.
