A NRC-identified finding of very low safety significance and an associated non-cited violation of
Technical Specification (TS) 5.5.1.a for the failure to perform an adequate technical review which led to the
Offsite Dose Calculation Manual (
ODCM) not being kept current. This issue was entered into the licensees corrective action program as
AR 01397500. The licensee is currently evaluating changes to the
ODCM. The performance deficiency was determined to be of more than minor safety significance in accordance with
IMC 0612, Appendix B, Issue Screening, because it was associated with the program and process attribute of the
Public Radiation Safety Cornerstone and the performance deficiency adversely affected the cornerstone objective to ensure adequate protection of public health and safety from exposure to radioactive materials released into the public domain as a result of routine civilian nuclear reactor operation. Specifically, the failure to maintain the
ODCM current adversely impacted the licensees ability to precisely determine offsite radiation dose under certain conditions. In accordance with
IMC 0609, Appendix D,
Public Radiation Safety Significance Determination Process, the inspectors determined that the finding had a very low safety significance (Green) because the finding was related to the Effluent Release Program but did not involve: (1) a failure to implement an effluent program; or (2) result in public dose exceeding a limit in
10 CFR 50 Appendix I or
10 CFR 20.1301(e). The inspectors identified that the primary cause of this finding was related to the cross-cutting aspect of human performance with the component of resources. Specifically, the licensee did not ensure the
ODCM (a procedure required by TSs) was up to date.
