Transient thermal analysis of PWR’s by a single-pass procedure using a simplified nodal layout

Abstract

PWR accident conditions and analysis methods have been reviewed. Limitations of the simplified method with respect to analysis of these accident conditions are drawn and two transients ( loss of coolant flow, seized rotor) identified as candidates for analysis by this method. These transients have been examined in detail by this one-stage approach (the simplified method). It is concluded that the steady state one-stage simplified method can be applied to the above two transient conditions.
