Abstract
The Random Finite Element Method (RFEM) has been adapted to determine the effect of the spatial variability of material properties in an Advanced Gas-cooled Reactor brick. The RFEM can be summarized as follows: (1) Generate a set of random fields; (2) Incorporate the random fields in a deterministic solver; (3) Analyse the statistical information of the response variables. Two different cases are proposed to study the influence of material properties variability. In the first case, a thermoelastic finite element analysis is employed to determine the effect of spatial variability of strains and stress distributions on a nuclear graphite brick. In this case, the chosen material properties are the Young’s Modulus and Coefficient of Thermal Expansion. For the second case, a methodology is proposed to measure the influence of porosity on the effective Young’s Modulus of graphite.
