The fault isolation caused loss of one of the required two | | off-site power sources to both Salem units. Auxiliary feedwater started on | | low steam generator level after isolation of main feedwater due to the | | reactor trip. All system functioned as required. The unit is stable in Hot | | Standby and an investigation into the cause of the electrical disturbance is | | underway. | | | | Two of four reactor coolant pumps tripped when the unit was tripped, which | | is expected with the partial loss of off-site power. Presently, the only | | major secondary equipment that is unavailable is associated with the loss of | | power to two of four non-vital 4 Kv buses. There is one shutdown Technical | | Specification in effect and that is associated with having only one off-site | | power source. | | | | The licensee notified the NRC Resident Inspector. | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ |General Information or Other |Event Number: 38314 | +------------------------------------------------------------------------------+ +------------------------------------------------------------------------------+ | REP ORG: DEFENSE MICROELECTRONICS ACTIVITY |NOTIFICATION DATE: 09/25/2001| |LICENSEE: DEFENSE MICROELECTRONICS ACTIVITY |NOTIFICATION TIME: 09:22[EDT]| | CITY: McCLELLAN REGION: 4 |EVENT DATE: 09/25/2001| | COUNTY: STATE: CA |EVENT TIME: [PDT]| |LICENSE#: AGREEMENT: Y |LAST UPDATE DATE: 09/25/2001| | DOCKET: |+----------------------------+ | |PERSON ORGANIZATION | | |GREG PICK R4 | | | | +------------------------------------------------+ | | NRC NOTIFIED BY: DAVID PENTROSE | | | HQ OPS OFFICER: BOB STRANSKY | | +------------------------------------------------+ | |EMERGENCY CLASS: NON EMERGENCY | | |10 CFR SECTION: | | |NINF INFORMATION ONLY | | | | | | | | | | | | | | +------------------------------------------------------------------------------+ EVENT TEXT +------------------------------------------------------------------------------+ | INCORRECT ACTIVITY SOURCE PROVIDED BY VENDOR | | | | The licensee called to report that a sealed source installed in their | | irradiator facility does not have the source activity specified.

This is a loss of one leg of double contingency | | as defined in NCSE 0705_076.E03. The presence of an unknown (at this time) | | amount of Uranium bearing material that was spilled (at some time in the | | facility's past) is a potential violation of passive design feature one of | | NCSA 0705_076.A03 which credits the physical integrity of X-705 system | | piping this would represent a loss of the second leg as defined in NCSE | | 0705_076.E03 | | | | Measurements are being conducted and are ongoing to determine amount of | | material, which may affect this report. | | | | | | | | SAFETY SIGNIFICANCE OF EVENTS: | | | | The safety significance of this event is potentially high (at this time) | | because the exact amount of Uranium bearing material that could have entered | | the opening in the block wall is unknown. Measurements to quantify the | | material are In progress. The apparent block wall construction (as evidenced | | by visual inspection of wall openings in the other areas of Recovery) | | indicates the potential for the presence of unfavorable geometry voids | | within and between the blocks compromising the exterior building wall. | | | | POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW | | CRITICALITY COULD OCCUR): | | | | If 1) a significant amount of uranium bearing material entered the void | | spaces of the block wall. 2) the material has collected in the multiple | | voids resulting in a single unfavorable geometry configuration. 3) the | | material has a high enrichment and uranium concentration, and 4) the | | material would become sufficiently moderated, then a potentially critical | | configuration could result. Note that no spills or leaks of uranium bearing | | material from present X-705 systems has occurred at this time. The material | | in question has apparently been there for some time. | | | | CONTROLLED PARAMETERS (MASS. MODERATION, GEOMETRY, CONCENTRATION, ETC.): | | | | Double contingency for inadvertent Containers relies upon the physical | | integrity of X-705 piping to prevent a spill of an unsafe amount of | | material. An unsafe amount is defined by the concentration and enrichment of | | the material. Double contingency also relies upon administrative controls | | limiting the presence of unfavorable geometry or unsafe volume containers | | that could collect a spill or leak. | | | | ESTIMATED AMOUNT. ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS | | LIMIT AND % WORST CASE OF CRITICAL MASS): | | | | Unknown at this time. Enrichment could be greater than 90% based upon | | historical operations. The form Is most likely uranyl nitrate or UO2F2. | | Measurements for determination of mass arid assay are currently in | | progress. | | | | NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION | | OF THE FAILURES OR DEFICIENCIES | | | | The openings leading to the interior spaces of the block wall is a violation | | of administrative control #3 of NCSA.705_076.A03 because the exact geometry | | or volume of the potential collection area is unknown. This is a loss of one | | leg of double contingency as defined in NCSE-0705_076.E03. The presence of | | an unknown (at this time) amount of uranium bearing material that has | | spilled (at some time in the facility's past) is a potential violation of | | passive design feature 1 of NCSA-0705_076.A03 which credits the physical | | integrity of X-705 system piping. This would represent a loss of the second | | leg of double contingency as defined in NCSE-0705_076,E03. | | | | CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED: | | | | Samples of the material have been taken and DNA measurements will be taken | | to determine amounts of material and assay. | | | | | | The NRC Resident Inspector was notified and the DOE Representative will be | | notified. | +------------------------------------------------------------------------------+
