Title 10 CFR 50, Appendix B, Criterion V, Instructions, Procedures, and drawings, requires, in part, that activities affecting quality be prescribed by documented instructions, procedures, or drawings, of a type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures, or drawings. Contrary to this, on February 6, 2017, the licensee failed to accomplish an activity affecting quality in accordance with licensee procedure,
CC AA 201, Revision 11, Plant Barrier Control Program. Specifically, the licensee failed to implement compensatory actions required by the Plant Barrier Control Program which resulted in multiple doors being impaired at the same time such that safety -related equipment in the Unit 2 Division II switchgear room and Unit 2 749 Auxiliary Building were declared
inoperable. The licensee documented the issue in their
CAP as Action Request (
AR ) 3972830. The inspectors determined that this issue was of very low safety significance because the finding: (1) was not a deficiency affecting the design or qualification of a mitigating structure, system, or component (
SSC ); (2) did not represent a loss of system and/or function; (3) did not represent the actual loss of safety 35 function of at least a single train for greater than its technical specification ( TS ) allowed outage time; (4) did not represent an actual loss of one or more non TS trains of equipment during shutdown designated as risk significant for greater than
24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />; and (5) did not degrade a functional auto- isolation of residual heat removal (
