CFR Title: 

Content:
cuits shall be verified for each sampled explosively actuated valve following removal of its charge. This must include confirmation that sufficient electrical parameters (voltage, current, resistance) are available for each valve actuation circuit. Corrective action shall be taken to resolve any deficiencies identified in the actuation logic or associated electrical circuits. (iv). For explosively actuated valves selected for test sampling every 2 years in accordance with the ASME OM Code, the sampling must select at least one explosively actuated valve from each redundant safety train. Each sampled pyrotechnic charge shall be tested in the valve or a qualified test fixture to confirm the capability of the charge to provide the necessary motive force to operate the valve to perform its intended function without damage to the valve body or connected piping. Corrective action shall be taken to resolve any deficiencies identified in the capability of a pyrotechnic charge in accordance with the preservice testing requirements. This license condition shall expire upon (1) incorporation of the above surveillance provisions for explosively actuated valves into the facility’s inservice testing program, or (2) incorporation of inservice testing requirements for explosively actuated valves in new reactors (i.e., plants receiving a construction permit, or combined license for construction and operation, after January 1, 2000) specified in the 2012 Edition (or later) of the ASME OM Code 3.9.6-28 Revision 4 – March 2017 as incorporated by reference in 10 CFR 50.55a, including any conditions imposed by the NRC, into the facility’s inservice testing program. 5. Inservice Testing Program for Dynamic Restraints A. The IST program for dynamic restraints is acceptable if it meets the requirements of the ASME BPV Code, Section XI, or the ASME OM Code as incorporated by reference in 10 CFR 50.55a. The IST program for dynamic restraints must comply with these provisions. The COL
