Abstract

PERT-K is a diffusion perturbation theory code developed by the Korea Atomic Energy Research Institute (KAERI) for use in fast reactor analysis. In past years, KAERI has also been developing an advanced fast reactor concept, KALIMER-600, which is a pool-type, liquid metal sodium cooled, metallic-fuelled fast reactor. For safety design, the reactivity effects in KALIMER-600 should be properly assessed. In this paper, various reactivity effects of importance in KALIMER-600 due to sodium void and fuel temperature change will be analyzed using PERT-K so as to examine its applicability to such reactivity feedback calculations in relation to the direct flux computations for the unperturbed and perturbed systems. It is found that the calculation results by PERT-K agree well with those by the diffusion code DIF3D.
