The Flash-2 Method for Loss-of-Coolant Analysis

A loss-of-coolant analysis method, FLASH, has been tested experimentally and improved. The more versatile FLASH-2 computer program that evolved produces results that agree with classical theory in the case of decompression of pipes and with experiment in the case of blowdown of water-filled tanks. Such agreement increases confidence in FLASH-2 as a rational basis for predicting the consequences of a loss-of-coolant accident.
