摘要

The core-loading pattern is decisive for fuel cycle economics, fuel safety parameters and economic planning for future cycles. ROSA, NRG's loading pattern optimization code system for PWRs, has proven to be a valuable tool to reactor operators for almost two decades for improving their fuel management economics in a more and more constrained environment. ROSA uses simulated annealing as loading pattern optimization technique, in combination with an extremely fast 3-D neutronics code for loading pattern calculations. The code is continuously extended with new optimization parameters and other functionality. This paper outlines recent developments of the ROSA code system with a focus on the new full core version, DNBR-capability, and a special End Of Life (EOL) loading pattern design application.
