Development and application of a multi-objective optimization code for neutronics calculation

The neutronics optimization design is an important step of complex reactor design. A Multi-Objective Optimization Code (named MOO1.0) for neutronics calculation was developed by FDS Team, which can get the optimal results of multi-neutronics objectives by adjusting material volume fractions and geometry sizes etc. considering calculation constraints. Then the MOO1.0 was verified based on some examples, and applied to optimize analysis of the fuel breeding performance for a gas-cooled fuel breeding blanket of a fusion driven sub-critical reactor.
