Response trees for emergency operator action at the LOFT facility

Following the onset of an accident which disables equipment used for normal reactor cooling, the first priority of the nuclear plant operator is to ensure that the reactor core is covered and that adequate cooling water flow is established. During this time, he must evaluate the situation, determine which emergency procedures apply, find the appropriate procedures, and perform the prescribed actions. Failure to respond quickly and effectively could result in expensive facility damages and potential hazards to the public. A procedure which attempts to streamline this short-term response process has been developed and implemented for the Loss of Fluid Test (LOFT) facility
