| Title | Licensee-Identified Violation |
| Description | Technical Specification 3.7.11, Condition A, required that an inoperable safeguards chiller water system (SCWS) loop be returned to operable status within 30 days. Technical Specification 3.7.11, Condition B, required that if Condition A was not met, both units must be in Mode 3 in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in Mode 5 in 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. As discussed in Section 4OA3.3 of this report and CAP 01120914, the 121 loop of SCWS was inoperable from October 1, 2007, through the time it was repaired on December 15, 2007, and neither unit was shut down. Since the leak was small enough not to affect functionality of the system, had not grown significantly, and was repaired in a timely manner once it was determined to be pressure boundary leakage, the violation was of very low safety significance |
