Technical Specification Limiting Condition for Operation 3.3.2 Condition I requires, in part, that with one channel of instrumentation inoperable, place the channel in trip in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in Mode 3 in 78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br />. Contrary to the above, between May 14 and May 22, 2008, the licensee placed steam generator level control hand switch 2-LS-0529C in the 2-LY-0529 position which caused the high-high level trip function for SG 2-02, protection set 1, narrow range level channel to be inoperable and failed to place the channel in trip in 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or be in Mode 3 in 78 hours9.027778e-4 days <br />0.0217 hours <br />1.289683e-4 weeks <br />2.9679e-5 months <br />. The licensee documented the violation in the corrective action program as condition report CR-2008-001804. The violation was determined to be of very low safety significance because it did not represent an actual loss of safety function of a single train of equipment. This is the enforcement aspect of the licensee event report discussed in Section 4OA3.2. |
