n 2 for non-LWRs. Basis for Regulatory Guidance Position 1 Since current regulations specifying standards to be used for preservice and inservice inspection programs are only applicable to light water reactors, an applicant for a non-LWR operating license should propose a license condition to implement an PSI/ISI program. If ASME Code, Section XI, Division 2 is to be used, the license condition should state that the program will follow this RG. For example, an applicant should propose a license condition similar to the following or with appropriate modifications: [Licensee] must implement and maintain in effect all provisions of a Reliability and Integrity Management program that satisfy the requirements of ASME Code, Section XI, Division 2, 2019 Edition, as further conditioned by the NRC’s endorsement in RG 1.246, “Acceptability of ASME Code, Section XI, Division 2, ‘Requirements For Reliability And Integrity Management (RIM) Programs For Nuclear Power Plants,’ For Non-Light Water Reactors,” Revision 0. Any departure from ASME Code, Section XI, Division 2, 2019 Edition, or the conditions and limitations in RG 1.246 must be submitted to the NRC for review and approval in accordance with 10 CFR 50.90. As discussed above, the regulations in 10 CFR 50.34(b)(6)(iv) and 52.79(a)(29)(i) require all applicants for operating and combined licenses to include plans for conducting normal operations, including maintenance, surveillance, and periodic testing of SSCs. Within Appendix A to RG 1.232 are several ARDC that relate to SSC testing. ARDC 1 states that SSCs important to safety are to be tested to quality standards commensurate with the importance of the safety functions to be performed. The license condition is necessary to ensure the program exists and will be implemented to ensure the safe operation of the SSCs throughout the life of the facility. The license condition will support the staff’s finding that 10 CFR 50.34(b)(6)(iv) and 52.79(a)(29)(i) are met
