Shutdown cooling was lost while hanging a tagout on the Reactor Protection System (RPS). When removing fuses as directed by the tagout, isolation logic for Shutdown Cooling suction salve 10MOV-18 was actuated. This Suction Valve isolates the common shutdown cooling suction line to all Residual Heat Removal (RHR) Pumps. At the time of the isolation cavity flood-up was in progress and the time to boil was greater than 5.5 hours. The appropriate Technical Specification LCO Actions were entered and shutdown cooling was restored at 08:27.</br>Power was restored to RPS and work in that system has been suspended pending the results our investigation into the cause of the event. Also additional controls have been established to review any electrical jumper/ protective tagging interactions prior to installation.</br>The event has been entered into the corrective action program and a Licensee Event Report (LER) will be filed within 60 Days as required by 10 CFR 50.73(a)(2)(v).</br>The resident inspector has been briefed and the state Public Service Commission (PSC) will also be notified.ce Commission (PSC) will also be notified. +
