| Title | Failure to Accomplish a Procedure for an Activity Affecting Quality in a Manner Appropriate to the Circumstances |
| Description | A finding of very low safety significance and an associated NCV of Title 10, Code of Federal Regulations (CFR), Part 50, Appendix B, Criterion V, Instructions, Procedures, and Drawings, was identified by the inspectors for the licensees failure to identify a degraded condition warranting compensatory measures/actions for assuring operability, as required by Section 4.3.12 of procedure EN-AA-203-1001, Operability Determinations/Functionality Assessments. Specifically, on April 29 and April 30, 2015, the licensee failed to accomplish procedure EN-AA-203-1001 in a manner appropriate to the circumstances to assess equipment operability following the identification of an unexpected condition associated with the flow indication controller (FIC) on the B Standby Gas Treatment (SBGT) subsystem. Following completion of the surveillance testing, the B SBGT system was initially declared operable and fully qualified. In response to questions from the inspectors, the licensee subsequently declared the B SBGT system operable but degraded. The licensee entered the issues associated with the FIC into the Corrective Action Program (CAP) as condition report (CR) 02044191 and CR 02044702, and entered the inspectors concerns into the CAP as CR 02052508. The performance deficiency was determined to be more than minor safety significance in accordance with IMC 0612, Appendix B, Issue Screening, dated September 7, 2012, because if left uncorrected, failing to properly assess operability as required by procedure could potentially result in incorrect/untimely operability conclusions, and the failure to take action to correct degraded or deficient conditions as required by the Technical Specifications. Specifically, the performance deficiency resulted in not properly assessing operability of the B SBGT subsystem that resulted in the failure to implement appropriate compensatory measures/actions to assure operability until final corrective actions were taken. The performance deficiency is associated with the Barrier Integrity attribute of systems, structures, and components and Barrier Performance associated with standby gas trains, which adversely affects the cornerstone objective. (To provide reasonable assurance that physical design barriers protect the public from radionuclide releases caused by accidents or events.) The inspectors applied IMC 0609, Attachment 4, Initial Characterization of Findings, issued June 19, 2012, to this finding. The inspectors answered No to all questions within Table 3, [Significance Determination Process] SDP Appendix Router, and transitioned to IMC 0609, Appendix A, The SDP for Findings At-Power, issued June 19, 2012. Per Exhibit 3, Barrier Integrity Screening Questions, the inspectors determined that because the finding only represented a degradation of the radiological barrier function provided by the SBGT system, the finding screened as very-low safety significance (Green). This finding was associated with the cross-cutting aspect of conservative bias in the area of Human Performance, because the licensee did not use decision-making practices that emphasize prudent choices over those that are simply allowable. Specifically, the licensees decision making practices in implementing EN-AA-203-1001 were non-conservative, and failed to identify the FIC-5828B process deviation as a degraded condition warranting compensatory measures/actions which resulted in incorrectly declaring the B SBGT subsystem operable and fully qualified.
