Abstract: The objective of the paper is to advance the HEFEST-M program module assigned to perform stressing calculation at NPP structures. It is a part of SOCRAT code which is being developed at Russia for nuclear safety analysis. HEFEST-M possibilities include nonlinear deforming, elastic-plastic and creep material models, contact interaction of deforming domains, high temperature creep calculations and other. The creep model was tested on experiments with domestic reactor steel. Mathematical models of the HEFEST-M and FEM discretization are presented in the paper. Some test results of calculations are discussed.
