MULTIFACTORIAL MODELS FOR HEAT CONDUCTION AND HIGH-TECH WAYS TO PROTECT FISSION MATERIALS

This study explores multifactorial models designed to analyze heat conduction and enhance protection for fission materials in advanced nuclear devices. By examining a spherically symmetric device with varying fuel element configurations, the research presents solutions to heat conduction equations under different boundary and continuity conditions. The bundled software developed allows for the precise estimation of thermal fields across multiple models, facilitating optimizations in fuel content, particularly for plutonium-238, and providing valuable insights into temperature profiles necessary for efficient device operation.
