to the NRC for review. Such documents would be prepared and submitted to assist the NRC staff in understanding the SMR design and/or the prospective applicant’s proposed approach to address specific regulatory or technical issues. The prospective applicant should understand that certain factors within its purview impact the schedule and efficiency of the NRC staff’s activities during DSRS development. For example, the prospective applicant’s willingness to share preliminary information on the design and the associated PRA with the NRC staff is fundamental to its timely development of a quality DSRS. The ability of the staff to formulate its review strategy and create useful draft DSRS content depends on the quality and timeliness of critical inputs from the prospective applicant. For example, early submittal of finalized or near final design information for use by the staff minimizes revisions to the DSRS sections. Preliminary PRA results and reliability assurance program list categorizations facilitate the staff’s understanding of the applicant’s safety/risk categorization strategy for the SSCs. If the design incorporates innovative features such as passive systems or simplified controls, early identification of these features to the staff facilitates timely identification of any unique regulatory issues. The prospective applicant should perform a detailed review and comparison of the SMR design against each section of the current SRP and should identify those SRP sections that are applicable or not applicable to the design. The prospective applicant should document the results of the comparison in the form of a gap analysis. To support timely interactions with the NRC staff, the prospective applicant may perform the gap analysis with preliminary design information 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
