Abstract

The methods used by Babcock and Wilcox to calculate hydrodynamic loadings on a reactor cooling system undergoing a postulated loss-of-coolant accident are described. Studies are presented to demonstrate that the CRAFT2 code is capable of predicting subcooled blowdown. Guidelines for preparing CRAFT2 analyses are explained, and the use of CRAFT2 results in satellite codes to calculate various reactor cooling system loadings is described.
