EL INSTRUMENTATION A. INTRODUCTION Purpose This regulatory guide (RG) identifies methods and procedures the staff of the U.S. Nuclear Regulatory Commission (NRC) considers acceptable for demonstrating compliance with NRC regulations to provide a reliable means to remotely monitor wide-range spent fuel pool levels to support implementation of event mitigation and recovery actions as required by Section 50.155, “Mitigation of Beyond-Design-Basis Events,” of Title 10 of the Code of Federal Regulations (10 CFR 50.155) (Ref. 1). This RG endorses, with exceptions and clarifications, the methods and procedures promulgated by the Nuclear Energy Institute (NEI) in document NEI 12-02, “Industry Guidance for Compliance with NRC Order EA-12-051, ‘To Modify Licenses with Regard to Reliable Spent Fuel Pool Instrumentation’,” Revision 1 (NEI 12-02) dated August 2012 (Ref. 2) as a process the NRC staff considers acceptable for meeting certain regulations in 10 CFR 50.155. Applicable Orders and Regulations • NRC Order EA-12-049, “Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events,” issued March 12, 2012 (Ref. 3). This order requires all nuclear power reactor licensees and construction permit (CP) holders to develop, implement, and maintain strategies to maintain or restore core cooling, spent fuel pool (SFP) cooling, and containment following a beyond-design-basis external event • NRC Order EA-12-051, “Order Modifying Licenses with Regard to Reliable Spent Fuel Pool Instrumentation” issued March 12, 2012 (Ref. 4). This order requires nuclear power reactor DG-1317, Page 2 licensees and CP holders to provide safety enhancements in the form of reliable wide-range SFP instrumentation for beyond-design-basis events. • General Design Criterion 4, “Environmental and Dynamic Effects Design Bases,” of Appendix A, "General Design Criteria for Nuclear Power Plants," to Part 50, “Domestic
