24-HOUR NOTIFICATION - (DELETED) CRITICALITY DETECTOR FAILED ROUTINE TEST At approximately 19:00 P.M. on May 27th, one of two criticality detectors for (DELETED) failed a routine source check. The failure resulted in the detector not being able to give a High alarm, which resulted in a loss of criticality detector coverage for (DELETED) at the (DELETED) at BWX Technologies. This situation presents no risk to the public or workers, since the (DELETED) have not had any fuel since February 20, 2001. The last time the (DELETED) criticality detectors were source checked (successfully) was on April 11, 2004.

This loss of criticality detector coverage is required to be reported to the NRC within 24 hours per 10CFR70.24 and 10CFR70.50(b)(2). The licensee notified the NRC Resident Inspector.
