formation and, subsequently, refine and revise the gap analysis as the design is finalized. To develop the DSRS, the NRC staff performs an in-depth review and comparison of the SMR design against each section of the SRP, similar to that performed by the prospective applicant, and reviews the prospective applicant’s gap analysis. For each section of the SRP, the staff determines whether the respective SRP section should be (1) referenced in the DSRS for “use as is” (i.e., the section is wholly applicable to the design), (2) included in the DSRS with minor “editorial” modifications (e.g., the SRP acceptance criteria is applicable but nomenclature changes are needed for design applicability), (3) replaced in the DSRS with an entirely new section (e.g., the design meets a regulatory requirement or accomplishes a safety function in a manner that is different from that described in the SRP section), or (4) deleted from the DSRS because the SRP section is not applicable to the design (e.g., innovative design features obviate the need for SSCs addressed in the SRP section). The staff documents this determination for each SRP section in a “safety review matrix” that illustrates the section-specific correlation between the SRP and the DSRS. The “safety review matrix” serves as DG-1325, Page-109 both an overview and a table of contents for the DSRS. The NRC staff prepares the DSRS in a format and with a numbering scheme that corresponds to the SRP. Similar to the SRP, each section/subsection describes the scope of review, identifies applicable requirements, identifies the acceptance criteria to be satisfied, and identifies relevant references for the reviewer’s use in making a reasonable assurance finding that the applicant has adequately addressed the applicable NRC regulations and requirements. Following submittal of the application, the NRC staff determines, with support from the applicant, whether design and operational details require the DSRS content
