Abstract

The scope of the modular code EAC (European Accident Code) is to describe physical phenomena which contribute to the reactivity balance in LMFBR whole core analysis under hypothetical accident situations. The PIN Mechanics module PINM, in particular, is a simplified plane strain finite element program which predicts the reactivity effects due to thermal dilatation and in-pin molten fuel motion. Thermomechanics is actually modelled using a series of initial strains which represent, successively, thermal dilatation, restructuring, irradiation swelling, plasticity and creep, together with cracking. In addition, this program predicts the time and location of cladding failure which are introduced in EAC as initial conditions for the subsequent out-of-pin molten fuel motion model. Several numerical results are presented to illustrate the versatility and the efficiency of this module in the framework of a large whole core analysis code such as EAC.
