Green. The inspectors identified a finding and associated
NCV of
Technical Specification (TS) 5.4.1 for failing to station a designated individual at the airlocks. Licensee procedure 2OHP4030227041, Revision 34 required that a designated person be available at the airlock at all times during fuel handling if both air lock doors are open.
TS 5.4.1, Procedures, requires, in part, that the applicable procedures recommended in
Regulatory Guide 1.33, Revision 2, Appendix A, February 1978, be established, implemented, and maintained.
Regulatory Guide 1.33 states, in part, that general plant operating procedures for refueling and core alterations should be covered by written procedures. Contrary to this requirement, on October 18, 2016, the licensee failed to implement procedure 2OHP4030227041, Refueling Integrity. In response to the inspectors concern, the licensee stationed the designated individual. The licensee entered the issue into their
CAP as AR210611898. The issue screened as more than minor because it adversely affected the Human performance attribute of the
barrier integrity cornerstone. The inspectors concluded the issue was of very low safety significance using
IMC 0609 Appendix G, Attachment 1 dated May 9, 2014 because the issue did not increase Core Damage Frequency or
Large Early Release Frequency. The finding included a cross-cutting aspect of H.9, training, because operations staff had an incorrect understanding of the procedural requirements.
