The FIGRO computer program calculates internal temperatures and fuel volume swelling in bulk oxide cylindrical fuel elements. The addition of a model of interfacial heat transfer, which includes conduction through a physical gap whose size is determined by fuel and clad differential thermal expansion and by fuel swelling is presented. In addition, the thermal conductivity of the clad is computed as a function of temperature, and that of the fuel clad gap as a function of temperature and gas composition. The new version is in production on the CDC-6600 computer. (NSA 22: 16324)
