Specifically, the updated CSA will: (1) revise the current CSA based on the latest methodologies consistent with current NRC guidance and acceptance criteria, (2) simplify the storage configuration by establishing two regions within the spent fuel racks (SFRs) located within the SFP, and (3) provide an evaluation that encompasses a future fuel design.
