should inform the NRC immediately. The staff recommends that the applicant provide information, when available and appropriate, to support its determination on whether addressing the design error can be deferred based on its level of impact on the NRC’s SE. A COLA that references a DC bears schedule risk associated with any safety-significant design errors in the referenced DC that are identified after certification. Such design errors that affect the NRC staff’s ability to reach conclusions necessary to support findings in the FSER, as described in “General Guidance” of this section of the RG, will require a change in the licensing-basis information. Although a freeze point does not directly relate to post-certification errors, similar considerations concerning safety significance apply. For each DC, the NRC may document safety-significant design errors and their resolution in an RIS and include additional errors, if any are found, in a supplement to the RIS. If the vendor decides to file a timely renewal of the certification, the NRC would expect these errors to be included in the scope of the review. Industry organizations or design-specific DCWGs, as described in RIS 2006-06, could additionally document such design errors and their resolution. C.2.17 Small Modular Reactors and Design-Specific Review Standards Prospective applicants have notified the NRC of their intent to submit applications under 10 CFR Part 52 for light-water SMR designs. The characteristics of SMRs present several potential policy, technical, and licensing issues for the NRC. However, the NRC staff has identified these issues and developed plans to address them and is prepared to review applications for all types of light-water SMRs as discussed in SECY-14-0095, “Status of the Office of New Reactors Readiness To Review Small Modular Reactor Applications,” dated August 28, 2014 (Ref. 102). DSRSs provide a means to enhance the effectiveness and efficiency of the NRC staff’s
