PDC-RFDC and PDC-CDC. The NRC staff considers the proposed PDC-RFDC and PDC-CDC to be equivalent in establishing the necessary requirements for SSCs that provide reasonable assurance that the facility can be operated without undue risk to public health and safety. The staff therefore considers the two-tiered approach to be an acceptable method for proposing PDC for non-LWRs using the LMP methodology. (3) Addition: Applicants adopting alternative approaches to proposing PDC based on similar risk-informed, performance-based licensing methodologies should provide suitable justification for their approaches and include any exemptions necessary. Exemptions are necessary if the full scope of PDC, as discussed above, is not addressed—that is, if the PDC do not cover all necessary design, fabrication, construction, testing, and performance requirements for all SSCs important to safety. For example, the justification may be that, to address specific elements of PDC scope not included here, the applicant has complied with other regulatory requirements that compel the applicant to provide the relevant information in other portions of the application. b. Addition: Additional information on fuel qualification: In addition to the material identified in NEI 21-07, Revision 1, Section C.5, Chapter 5 of a SAR following NEI 21-07, Revision 1, should also address fuel qualification. The reactor core and its fuel are generally classified as SR, because they are directly involved in performing fundamental safety functions. The application should provide the information for SR SSCs identified in NEI 21-07, Revision 1, Chapter 6, “Safety-Related SSC Criteria and Capabilities.” However, other information such as fuel design limits, is attributed to or identified with fuel performance and its qualification. In particular, fuel cannot be qualified without irradiation data collected over certain time frames. Accordingly, non-LWR applicants may use existing data (e.g., Advanced
