an for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition,” Section 19.3, “Regulatory Treatment of Non- Safety Systems (Passive Advanced Light Water Reactors)” (Ref. 9). The preoperational tests for RTNSS may also satisfy some ITAAC testing requirements. The NRC staff’s safety evaluations of ITPs are based on FSAR information in the OL application submitted under 10 CFR Part 50. For a COL issued under 10 CFR Part 52, the staff’s safety evaluation of the ITP is based on information provided in the FSAR portion of the COL application. The staff uses this information to support decisions to issue a COL. In addition, the NRC uses the information provided in the FSAR as a basis for the inspection activities associated with ITPs. The satisfactory performance of approved test programs helps confirm that adequate safety margins exist, such that there is no undue risk to the health and safety of the public as a result of facility operation. This regulatory guide endorses the use of one or more voluntary consensus codes or standards developed by external organizations. These codes or standards may contain references to other codes or standards. These references should be considered individually. If a referenced standard has been incorporated separately into NRC regulations, licensees and applicants must comply with that standard as set forth in the regulation. If the referenced standard has been endorsed in a regulatory guide, the standard constitutes a method acceptable to the NRC staff for meeting a regulatory requirement as described in the specific regulatory guide. If a referenced standard has been neither incorporated into NRC regulations nor endorsed in a regulatory guide, licensees and applicants may consider and use the DG-1259, Page 7 information in the referenced standard, if appropriately justified and consistent with current regulatory practice. Appendix A references existing regulatory guides that are applicable to ITPs. The
