| Title | Licensee-Identified Violation |
| Description | Prairie Island Technical Specification 5.4.1, Procedures, required, in part, that written procedures shall be implemented covering the applicable procedures recommended in Regulatory Guide 1.33, Revision 2, Appendix A, February 1978. Regulatory Guide 1.33, Revision 2, Appendix A contains, in part under Section 1, Administrative Procedures, Subsection e., Procedure Review and Approval. Contrary to the above, on December 12, 2013, and June 11, 2013, the licensee failed to properly implement FPGDOC04, Procedure Processing, Revision 19, to ensure that validation reviews were performed to ensure usability of C18.1, Engineered Safeguards Equipment Support Systems, following revisions to the procedure. Specifically, validation reviews were not performed during procedure revisions of C18.1 which lead to inadequate instructions to ensure that SCWSsupported system operability was properly addressed when SCWS functions were affected. This led to seven instances of conditions prohibited by TS for safeguards buses 15 and 16 between January of 2013 and May of 2015. The licensee later determined that although conditions prohibited by TS did occur based on the inadequate C18.1 instructions, an equally correct application of TS would have been to enter a 30day action statement for one SCWS inoperable per TS 3.7.11 and apply Surveillance Requirement 3.0.6 by performing a SFDP evaluation. This would not have resulted in conditions prohibited by TS for the supported AC or DC systems. Because the inspectors answered No to all questions under Exhibit 2 of Inspection Manual Chapter (IMC) 0609, Appendix A, The Significance Determination Process (SDP) for Findings At-Power, the finding screened as very low safety significance (Green). The above issue was documented in the licensees CAP as CAP 1488482. Corrective actions included changes to C18.1 to implement the SFDP for future SCWS removals from service, and revisions to the FPGDOC04 job familiarization guide to ensure validation reviews are properly performed. |
