The SBV System action statement was entered when the plant declared Relay Flacks RR-119 and RR-120 inoperable due to non-qualified fuses and cables being installed in six (6) of the boxes contained in these racks. The instruments associated with the six (6) boxes were not found in Technical Specification required instruments or alarms. The issue was that a downstream failure on the non-qualified Instruments may not have qualified fault protection, therefore a fault could impact safety related equipment. Other Technical Specification equipment affected by the inoperability of RR-119 and RR-120 include both trains of Inadequate Core Cooling Monitoring System (ICCMS), Reactor Vessel Level Indication (RVLIS), Pressurizer Safety Valve Outlet Temperature, and Pressurizer Power Operated Relief Valve Outlet Temperature.</br>At 1611 actions taken by plant staff returned RR-120 to operable and the 12 hour action statement for SBV was exited. The plant remains in a 7 Day Limiting Condition of Operation (LCO) pending the return of RR-119. Due to the fact that Train B of SBV has been made operable, a plant shutdown was not commenced.</br>This event is being reported under 10CFR50.72(b)(3)(v)(C) 'Any event that at the time of discovery could have prevented the fulfillment of the safety function of systems that are needed to control the release of radioactive material'.</br>The licensee notified the NRC Resident Inspector.ensee notified the NRC Resident Inspector. +
