- 00 Based on the leakage identified on April 16, 2016 and the subsequent leakage identified on April 22, 2016 that was sufficient to require declaring RCIC inoperable, RCIC is considered to have been inoperable prior to mode change. As a result, the condition is considered to be a violation of Technical Specification 3.0.4 and reportable in accordance with 10 CFR 50.73(a)(2)(i)(B) as a condition prohibited by Technical Specifications.
