Determination of irradiation conditions of WWER-1000 reactor internals

Abstract

The calculational procedure for determination of irradiation conditions of WWER-1000 reactor internals is presented. Using developed procedure, irradiation conditions of WWER-1000 reactor internals, first of all, baffle and barrel, are determined for a set of fuel cycles. Distributions of neutron flux functionals on surfaces of internals are analyzed for different fuel cycles.
