Book Description

Analysis of Primary Containment Transients (APRICOT) is an ERDA sponsored project in which a variety of reactor safety analysis groups around the world have been invited to participate by performing calculations to verify capabilities of large computer codes used to analyze postulated core disputive accidents of liquid metal fast breeder reactors. Nine groups have performed calculations of the first three problems which were set, using ten computer codes. Two problems were simple test problems for which analytical solutions exist, namely an ideal gas shock tube, and a suddenly pressurized spherical cavity in an infinite elastic medium. The third problem concerns an explosion in a partially water-filled overstrong cylindrical containment vessel for which experimental data exist. A critique of the results of these calculations is given in the paper.
