High Pressure Coolant Injection System Inc … High Pressure Coolant Injection System Incapable of Performing its intended Safety Function.</br>This report is being made in accordance with 10 CFR 50.72(b)(3)(v) due the High Pressure Coolant Injection System being incapable of performing its intended safety function.</br>At 1810 hours (CDT) during performance of the functional test of the level instrumentation for the automatic realignment of the High Pressure Coolant Injection system (HPCI) suction sources, plant maintenance person identified that logic circuitry leads had been lifted. The leads not being connected would prevent the automatic realignment of the HPCI suction from its non-safety related source, the Condensate Storage Tank (CST), to its safety related source, the Suppression Pool.</br>Based on preliminary information, the leads were lifted during scheduled maintenance activities on the HPCI system in March.</br>The applicable Technical Specification specified that HPCI be declared inoperable within an hour. Actions were immediately taken to restore the automatic function. The leads were re-landed and the TS condition exited at 1853 hours.</br>The inability of the system to automatically realign due to a CST low level or a Suppression Pool high level is considered to be a condition that would prevent the fulfillment of the safety function of the HPCI system.</br>The licensee is still investigating the cause.</br>The NRC Resident Inspector was notified..
