The FA2D/PARCS code system has been validated on NPP Krsko operational data (Cycles 1 and 21). It is modified at FER to enable internal 3D depletion calculation and usage of neutron cross section data in a format produced by FA2D and interface codes. PARCS is an advanced nodal code developed at Purdue University for US NRC and it is based on neutron diffusion theory for three dimensional whole core static and dynamic calculations.
It generates homogenised cross sections both of single pins and entire fuel assemblies. FA2D is a multigroup two dimensional transport theory code for burn-up calculations based on collision probability method, developed at FER. It consists of two codes: FA2D and PARCS. International Nuclear Information System (INIS)įA2D/PARCS code package is used at Faculty of Electrical Engineering and Computing (FER), University of Zagreb, for static and dynamic reactor core analyses.
