Genetic Algorithms are used in MJTR core loading pattern optimization programming. Encoding and crossover operators were designed relating the characteristics of the real problem. The two dimensional hexagonal geometric multigroup diffusion code SIXTUS 2 is used in fitness calculation. For improving the quality and efficiency of the program, many math experiments have been done to find the optimal methods and parameters. Results of the optimization calculation show that all genetic algorithms optimized loading pattern are better that expert′s loading pattern. The optimized schemata and optimized loading pattern of MJTR core are given.
