Water-reactor computer-codes which model behaviour during normal- and transient-operation

The IAEA has instituted a Consultant Panel, concerned with the use of computer codes to model the behaviour of water reactor fuel elements. Codes have been developed in many countries and model the behaviour under both normal and off-normal conditions. A special class of codes predict the probability of certain end-points such as clad-failure. One task which the IAEA has set for the Consultants panel is the preparation of a comprehensive review of fuel elements computer-codes. The present paper is a draft of that review, prepared by the Chairman of the Consultants (JH Gittus) and two of the Consultants (IB Misfeldt and Erik Rolstad)
