Water reactor fuel performance codeprofess and its application for predicting the behaviour of the fuel elements of D-Com blind problem

Abstract

This paper gives a brief description of the sub-models of important phenomena treated in computer code PROFESS arid presents some results of PROFESS calculations for the fuel elements of D-Com blind problem.

Measurement of fission gas release, internal pressure and cladding creep rate in the fuel pins of PHWR bundle of normal discharge burnup

“…The fuel centre temperature and fission gas release behaviour were analyzed using computer code PROFESS, which is an axisymmetric one dimensional code applicable to Zircaloy clad UO 2 fuel pins of water cooled reactors [10,11]. In this code fuel pellet cross section is divided into 50 concentric rings of equal width for calculation.…”
