The fuel-pin modeling code, LIFE-GCFR, has been developed to predict the thermal, mechanical and fission-gas behavior of a Gas Cooled Fast Reactor (GCFR) fuel rod under normal operating conditions. It consists of three major components: thermal, mechanical and fission-gas analysis. LIFE-GCFR predictions have been checked against experimental observations. The overall good agreement of predictions with test results demonstrates that LIFE-GCFR is, in its present state, a suitable tool for predicting the thermal, mechanical and fission-gas behavior of GCFR fuel rods. The reference GCFR fuel-element design was analyzed with this verified LIFE-GCFR code under various operating conditions, and the results are discussed. Finally, suggestions for further research are given. Modeling efforts in off-normal and/or design-basis transient analysis, axial blanket analysis, fission-gas analysis with fast running capability, and the analysis of highly localized fuel and cladding behavior are recommended.
