【摘要】 核电站堆芯多循环换料设计最优化是燃料管理研究中的一个难点。通过变量代换将问题中的两种耦合关系分解开,使得该问题转化为一个含有复杂约束条件的非线性规划问题。开发了一种求解复杂约束非线性规划的新方法——概率逼近法(PAM),有效地求解了该问题。在一个实际核电站堆芯模型上的计算取得了满意的效果。更多还原

【Abstract】 Multi-cycle refueling design optimization in nuclear plant is a complex problem in fuel management research.The two different kinds of combined relations in this problem are de-coupled by variable replacing,and the problem is changed into a non-linear programming problem with complex constraints.A new probability method-Probability Approaching Method is developed to solve this non-linear programming problem.The results on a real reactor core model show the benefit of multi-cycle optimization.更多还原
