Generic Comment.
2 Page 2-3, Section 2.1.2.1.1 Paragraph 4 Concerning exposure duration, the applicant concluded that long-term exposure to conditions resulting from a failed NSR SSC (such as leakage or spray) is not considered credible. The basis for this conclusion is that leakage/spray would be quickly identified by plant personnel via walkdowns, sump-level trends, or system parameter monitors and alarms. Once identified, appropriate corrective actions would be taken. Therefore, only NSR SSCs whose failure could result in a failure of an SR SSC due to short-term exposure would need to be considered within the scope of license renewal pursuant to 10 CFR 54.4 (a)(2).
