On the sensitivity of HCPWR microcell calculations to geometrical treatment

Abstract

Nuclear reactor microcell calculations are, normally, carried out using simplified geometrical models which do not include the total number of homogeneous zones actually present. Regarding the particular case of High Conversion Pressurized Water Reactors (HCPWR) , the revision of this approximation has been done to determine the sensitivity of its neutronic parameters to the use of these models.
