ENS 4706015 July 2011 16:01:0010CFR74.57(f)(2) requires notification within 24 hours that an MC&A (Material Control and Accounting) alarm resolution procedure has been initiated. In the solvent extraction area of Building 333, the input minus output value exceeded the MC&A limit. Because the alarm investigation procedure has been initiated, this notification is being made. There is no indication that a material loss has occurred. MC&A process monitoring tests for material balance were run as specified by applicable procedures and requirements. Based on the test results for the Building 333 solvent extraction area, the test limit was exceeded. An investigation is currently underway to resolve the issue. There were no actual or potential safety consequences to workers, the public, or the environment. The licensee has notified the NRC Resident Inspector.
