During an engineering review it was discov … During an engineering review it was discovered that for certain fire scenarios affecting the auxiliary building west motor control center - rod control room, the previously established fire safe shutdown strategy might not be successful. Specifically, for a fire in the west motor control center - rod control room, fire safe shutdown would be accomplished utilizing an unaffected charging pump. During an engineering review, a vulnerability was identified in which under certain circumstances the spurious closure of a charging pump suction valve could result in a loss of the running charging pump and the unavailability of the remaining charging pumps due to potential fire damage. The result is that all charging pumps could be affected by the fire and be unavailable to support fire safe shutdown in accordance with established procedures.</br>Compensatory actions to minimize risk of fire in areas of concern are being implemented.</br>This condition is being reported pursuant to 10 CFR 50.72(b)(3)(ii)(B).</br>The NRC Resident Inspector has been notified."
