With both trains in7erable. Technical Specification 3.0.f applies and states in part; when a Limiting Condition for Operation is not met, and required action is n1t specified or cannot be satisfied, within one hour initiate the action iecessary to place the affected unit in a condition in which the equipmen: is not required to be OPERABLE.
