This put the facility under LCO T.S. 3.3.a.2.C (one RHR heat ex changer may be out of service for up to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />) and thus is reportable per T.S.

6.9.2.b.2.

Since this valve was manually operable, and the second RHR heat exchanger was available, there was no effect on public safety or plant operation.
