CANDU fuel management optimization using alternative gradient methods

摘要

CANDU fuel management can be optimized for efficient reactor operation and reduced fueling costs. The quasi-linear programming approach developed in the OPTEX code for CANDU fuel management optimization has been implemented in the multipurpose mul-tigroup diffusion code DONJON. With new reactor designs and requirements for advanced reactors, alternative gradient methods are presented and tested to address more complex CANDU fuel management problems.
