Abstract

Abstract

The MCATHAS system of coupled neutronics/thermal-hydraulics in the supercritical water reactor is described,which considers the interaction between the obvious axial evolution of material temperature and density and the power distribution.This code is coupled externally.The MCNP code with the library of continuous cross section is used for neutronics analysis.The sub-channel code ATHAS is for thermal-hydraulics analysis and the ORIGEN code for burn-up analysis.The calculation results for the assembly of HPLWR show that the results from this code is reliable.
