SMARTT - A Computer Code to Predict Fuel and Pressure Tube Temperature Gradients Under Asymmetric Coolant Conditions

Abstract

A new fuel bundle heat transfer code called SMARTT (Simulation Method for Azimuthal and Radial Temperature Transients) is described. Practical applications of the code are presented, along with a sample calculation which demonstrates the capabilities of the code for use in accident


analysis of CANDU reactors. SMARTT is shown to be a useful tool for assessing pressure tube integrity under asymmetric coolant or geometric conditions.
