Methodology for risk assessment of major fires and its application to an HTGR plant
A risk assessment methodology is presented for a specific class of reactor accidents, major fires. Principal elements of the methodology include collection and interpretation of experience data, identification and screening of important fire locations, event tree/fault tree analysis, and accident consequence assessment. About 900 reactor-years experience was examined for reported fires either during construction or plant operation. Statistical analyses were performed of fire initiation and progression characteristics such as occurrence rate, distance of fire spread, and time to bring fire under control.
