The ability to manually open 23MOV-19 from the control room was unaffected as such, the HPCI system remained available for use. Failure of 23MOV-19 to open automatically prevents the HPCI system from performing its safety function as such this condition renders HPCI inoperable but available and is being reported as a condition that could have prevented the fulfillment of the safety function of a system needed to mitigate the consequences of an accident per 10CFR50.72(b)(3)(v)(D).</br>HPCI inoperable placed the licensee in a 14-day limiting condition for operation for Tech Spec 3.5.1.c.</br>The NRC Resident Inspector was notified..
