| Title | Incident Report on Unresolved Material Discrepancy Alarm |
| Event Description | 10 CFR 74.57(c) requires notification of any MC&A (Material Control and Accountability) alarm that remains unresolved beyond the time period specified for its resolution in the licensee's Fundamental Nuclear Material Control Plan. In the Solvent Extraction area of Building 333, [there is an abrupt alarm value.] When the alarm test was run on 8/15/2008, the input minus output value [exceeded the abrupt alarm value.] The investigation is completed but the alarm is not resolved. Measurement data for one of the inputs is the most assignable cause. Although an assignable cause was not identified, there is no indication that a material loss has occurred.
The affected solvent extraction process has been shutdown by the license while alarm resolution is in progress. The NRC Resident Inspector has been notified. |
