A self-revealing
NCV of
Technical Specification (TS) 5.7.1,
High Radiation Area, for an unauthorized entry into a
high radiation area (
HRA). The radiological aspects were not discussed in the pre-job brief, the health physics (
HP) technician in containment did not challenge the crew as to whether or not they received their
HRA briefing, and the crew did not follow adequate radiological safety practices, such as reading instructions on the
HRA posting prior to entry and not leaning against piping. The licensee entered this issue into the
CAP as CR 870060 The entry into a
HRA without meeting the entry requirements specified in T.S. 5.7.1 was a performance deficiency. This performance deficiency was more than minor because it was associated with the
Occupational Radiation Safety cornerstone attribute of Human Performance and adversely affected the cornerstone objective in that workers who enter
HRAs with inadequate knowledge of current radiological conditions could receive unintended occupational exposures. The finding was evaluated using the
Occupational Radiation Safety Significance Determination Process and determined to be of very low safety significance (Green). This finding does not involve a cross-cutting aspect because it is not current license performance.
