Abstract

The computer code BUTRAN is described. This is a fast running computer code designed to study boildown transients in bundles of fuel pins under accident conditions. The effects of rod to rod and rod to vapour thermal radiation are considered. During the heat up phase of the accident the zircalloy cladding reacts chemically with the steam coolant. The heat and the hydrogen produced by this reaction are calculated and the effect of the hydrogen concentration considered. Input instructions for BUTRAN are given together with two sample test cases to enable a user to set up an input deck.
