During the last decade,considerable progress has been in developing coarsemesh methods and modern nodal methods for solving the three-dimensional neutrondiffusion problems.However,to apply these methods successfully in the fuel management calcula-tions for the realistic light water reactor,we must solve the following problems:(1)Calculation of the nodal(assembly)homogenization parameters;(2)Calcul-ation of the detailed power distribution and the local quantities in an assembly;(3)Account explicitly for the local...

近几年发展的粗网法和现代节块法应用于水堆堆芯燃料管理计算,必须解决以下几个问题:①节块(组件)均匀化参数的计算;②组件内精细功率分布和局部量的计算;③由于燃耗和功率反馈效应等所引起的局部截面变化的考虑。本文将评述这些问题的最近国内、外研究进展.

Some countries have been devoting major efforts to developing the high burn-up fuel for pressurized water reactors.Target discharge batch average burnups aregenerally accepted to be in the range of 50 to 55 MWd/TU Therefore,the utiliza-tion of uranium is substantially improved.The high burnup fuel will continuallyreplace the current fuel.These are the retrofittable improvements.This reportbriefly discribes the design characteristics,fuel management,economic benefits,development programs and prospect on high...

许多国家正在大力发展压水堆高燃耗燃料,其批平均目标卸料燃耗能够达到5.0—5.5万兆瓦天/吨铀,因此显著地提高了铀利用率。高燃耗燃料即将陆续取代现行的燃料,这标志着压水堆燃料的更新换代。本文简要介绍高燃耗燃料的设计特点、燃料管理、经济效益、发展计划及发展前景等。

In the in-core fuel management model that has been developed in this paper, the fast group parameter is calculated using B_1 approximation and the thermal group parameter using the first flight collision probability method, but the critical and depletion calculations are based on the coarsemesh method.The nodal imbedded calculation, combined with the coarsemesh calculation, can give ths detailed flux and power distribution in assemblies.

在本文提出的堆芯燃料管理计算模型中,快群参数用B_1近似计算;热群截面的计算采用首次飞行碰撞几率法;而堆芯临界、燃耗计算是建立在粗网展开法的基础上。与粗网计算相配合的节块嵌入计算,能给出燃料组件内的精细通量、功率分布。
