| Abstract: | The improved Gear method-IGear for solving the point reactor neutron kinetics equations is presented.Because of its higher order and greater region of stability,it can not only retain the advantage of gear-better applicability and precision,but also improve its shortcoming.So the IGear method can be applied to different kinds of reactivity conditions with flexibility.The numeric results indicate: From the cpu time and accuracy,IGear can meet the demand of the practical engineering completely,so it is a better method for solving point reactor kinetics equations. |
