Abstract

A description of the calculation method which was applied for the simulation of the irradiation history of an assembly of different MOX fuel rods in the BR2 is given in the paper. The Monte Carlo simulation of irradiation experiment (OMICO) consisting of 16 MOX rods of different fuel compositions and assembled into two separated bundles one over other and loaded into one of the in-pile sections of the PWR simulation loop in BR2 was performed using the BR2 model with an interface module linking the input data for the MCNP and SCALE codes. The results of a direct Monte Carlo simulation are compared with the results of online thermal balance measurements of the power distribution in the IPS1 in-pile section comprising the OMICO bundles. In most cases the difference between the experimental and calculated values is less than 7-10%
