Abstract

This study outlines the design tool and coupled analysis for heat transport in a space heat pipe reactor to provide power in a space environment for 10 years without fuel replacement. Korea Atomic Energy Research Institute (KAERI) has developed the design analysis tools to investigate the temperature distribution and maximum temperature in the reactor core. The neutronics code, McCARD, provides the power profile of the fuel compact in the core. The heat transport code, HEPITOS, predicts the temperature profiles coupled with the heat pipe analysis code, LUHPIS.

Since each code has different physics, the numerical calculation can be performed by the explicit method or the coupled method. Most studies have been analyzed using the coupled calculations of HEPITOS and LUHPIS. The coupled analysis with the neutronic code has been done to find out the feasibility of the coupled system development. The calculated results will be a reference for the evaluation of the thermal margins of the components.
