摘要/Abstract

摘要： 用四阶龙格-库塔方法求解聚变-裂变混合反应堆堆芯等离子体动力学方程组,求解过程采用分段步长法,既可保证求解精度又可节省机时,所得出的解的曲线能充分反映堆芯等离子体的燃烧过程。求解过程还引用数值反馈控制方法用以对解曲线的优化和控制。这种数值反馈控制方法可以在工程技术上用来探索堆芯等离子体燃烧过程的控制。

关键词: 等离子体动力学方程, 聚变-裂变混合堆, 数值反馈控制

Abstract: Solving dynamics equations of plasma in fusion-fission hybrid reactor core is performed by using Runge-kutta method.Taking different step-length at different time segment is used through computation which can ensure the solution accuracy and save CPU time. There obtained solution curves fully display burning process of plasma in reactor core. In addition, value feedack control method applies to optimization and control of solution curves.

Key words: dynamics equations of plasma, fusion-fission hybrid reactor, value feedback control
