| Title | Required Appendix R Instrumentation Not Functional on Unit 4 Alternate Shutdown Panel |
| Description | The inspectors identified an URI regarding the processes and procedures used to evaluate the impacts of Appendix R steam generator (S/G) pressure indicators (PIs), when two of three PIs used for the Unit 4 alternate shutdown panel (ASP) 4C264 were designated as non-functional for approximately ten months. Specifically, the lack of the two S/G PIs during a fire event that requires main control evacuation may have adverse impacts on the ability to safely shutdown the plant and the effects of this condition may not have been evaluated. The USFAR, Revision C26, Appendix 9.6A, Fire Protection Program Report, Section 5.0, Alternate Shutdown Capability, stated, in part, that instrumentation and controls to achieve and maintain hot standby are provided on the ASP and supplemented by manual actions at local stations for achieving cold shutdown. Table 9.6A-2 in Section 5.0, lists components, instruments, and controls required for alternate shutdown. This table included PI-3(4)-1606/-1607/-1608, S/G pressure for A/B/C respectively. On January 29, 2015, the inspectors identified there were three ARs/works requests (WRs) on 4-PI-1606 and 4-PI-1607. These were two of the three required Appendix R S/G PIs on the Unit 4 ASP. The ARs were initiated on October 16, 2013; April 24, 2014; and July 13, 2014. At the time of discovery, the licensee did not have compensatory actions in place for this condition. The licensee captured the inspectors concerns in their corrective action program as AR 02027171, and initiated an apparent cause evaluation. As a result, the licensee performed a calibration check on 4-PI-1607 on February 21, 2015, under work order (WO) 40316782-01 and identified that the surveillance was satisfactory. In addition, they performed corrective maintenance on 4-PI-1606 on February 25, 2015, under WO 40262270-02 and returned the PI to functional status. Based upon the two non-functional S/G PIs on Unit 4 ASP for approximately ten months, the inspectors requested additional information, including the completed apparent cause evaluation, to determine if the licensee followed their processes and procedures required for Appendix R equipment. This issue is unresolved pending further licensee analysis to resolve the issue and to determine if a performance deficiency exists. This issue is identified as URI 5000251/2015007-02, Required Appendix R Instrumentation Not Functional on Unit 4 Alternate Shutdown Panel. |
