ABSTRACT
MULTIOBJECTIVE SIMULATED ANNEALING METHOD IMPLEMENTATION FOR PWR FUEL LOADING PATTERN OPTIMIZATION USING COREBN CODE. Optimizing loading/reloading pattern design is one of nuclear fuel management activities in order to reduce fuel cycle costs while satisfying safety constraints and operational targets. Multiplication factor at the end of cycle and maximum power peaking factors are the parameters to define the optimal LP design. This optimization initial fuel loading pattern study is based on multiobjective simulated annealing algorithm which is coupled to COREBN code for core burn up calculation. Optimization is implemented on ¼ core model (52 fuel assemblies) which represent the whole core. The result will then be compared to standard model in order to observe the improvement.
