【摘要】 为低泄漏堆芯燃料管理发展了一种多循环优化方法和程序系统。多循环优化过程分三步完成：第一步，用线性规划确定能使多循环总寿期最长的相继各循环功率份额最佳分布和循环长度最佳分配；第二步，以前一步结果为条件，用线性规划或直接搜索法对多循环中相继的各个单循环进行燃料组件的优化布置；第三步，用可变容差法（ＦＴＭ）实现可燃毒物最佳配置。更多还原

【Abstract】 A multi cycle optimization approach and program system is developed for a low leakage in core fuel management. In this system, the multi cycle optimization process is achieved in three stages:At first, use a linear programming method to find an optimum power sharing distribution and optimum cycle length distribution for the successive several cycles. which yields maximum multi cycle total cycle length. Secondly, detenmine the optimum fuel arrangment on the basis of the Former stage results by employing a linear programming method or directly search method for successive every one of the multi cycle. In the third stage, optimize the burnable poison assignment by Flexible Tolerance Method (FTM).更多还原
