image001.png Ed, The NRC staff has a question regarding the statement, The surveillance history review did not find any cases where the required integrated leak tests were not performed within the 18-month interval (including the 25% grace period). It is the staffs understanding that the history review is intended to identify if there were any failures of the SR over the last 5 cycles or that would not have been otherwise detected by SR or routine plant activities (not if the tests have been faithfully performed per schedule, as stated). Please clarify the results of past SR performances, not just that they had been performed within required periodicity. Additionally, please clarify if your conclusion that the impact of the frequency change on safety is small based in large part on the fact that more frequent walkdowns of the system and contamination survey efforts should pick up on any developing leakage.
Please contact me if a clarifying call is needed.
Thanks Lynnea
