Research is conducted in nuclear fuel menagement and electrical generation dispatch through the use of supercomputers. The research utilizes the capability of a supercomputer to provide for large-scale optimization of multi-cycle, nuclear-reactor core-reload design. The research also involves electrical power system intergration and generating unit reliability. An important objective is to incorporate realistic core physics modeling into the optimization search procedures. A sophisticated nodal code is to be converted to vector form for this work. The objectives are pursued with the initial focus upon using accelerated direct-search techniques for core-reload optimization. Also, fixed absorber loading is to be an additional degree of freedom in the modeling. Simplified utility system intergration and reliability models are incorporated into the optimization procedure. A sensitivity study is also carried out to learn the level of modeling detail that is significant for these parameters.
