m as-built reconciliations of piping; c. design features installed as a result of the completed pipe break hazards analyses; d. an update to turbine missile generation analyses, as necessary, based on as-procured material data; e. an update to reactor vessel materials data, as necessary, based on as-procured vessel material data; and f. a specific subset of FSAR information that was identified during the original licensing review (e.g., the applicant could provide a commitment to include information associated with vendors in an FSAR update at least 60 days before the initiation of construction). The NRC staff considers the above types of information to be appropriate to include in a timely FSAR update on a schedule that is more suitable for ensuring an updated design basis for initial operation of new plants than that required by 10 CFR 50.71(e). For example, the updated information would ensure that the design basis for the facility is up to date before, for example, fuel load, initial criticality, and exceedance of 5 percent of the authorized power level. The COL applicant should specifically identify these FSAR information requirements and consolidate them under a license condition that includes a proposed milestone for implementation. The NRC staff considers this information to be sufficiently relevant and distinct from the types of information typically included in routine FSAR updates to warrant its inclusion in a license condition. Along with the requirements of 10 CFR 50.71(e) and 10 CFR Part 52, this type of license condition furthers the NRC’s goal of ensuring that the design basis for the facility (i.e., the FSAR) is up to date when operation of the facility begins. Final SAR Information Commitments Included in a Routine Final SAR Update The periodic FSAR updates required by 10 CFR 50.71(e) should include updated information that does not warrant inclusion in the above categories or that occurs after the milestone associated with the license condition.
