摘　　要：基于经典的“两步法”压水堆计算流程,采用目前最先进的核反应堆物理计算方法,研发了先进的压水堆燃料管理软件Bamboo-C。Bamboo-C软件主要由3个功能程序(LOCUST、SPARK、LtoS)组成,LOCUST为二维组件非均匀及等效均匀化计算程序,SPARK为三维堆芯稳态/瞬态分析程序,LOCUST和SPARK程序之间通过组件均匀化参数函数化程序LtoS链接。Bamboo-C软件具备完善的压水堆燃料管理与核设计必备的分析功能,主要包括:启动物理试验、动力学参数计算、控制棒微积分价值、功率运行跟踪等。最后,基于我国自主研发的CNP300、CNP650和CNP1000堆型的运行数据,完成了Bamboo-C软件的工业确认工作。结果表明,采用Bamboo-C软件获得的临界硼浓度、温度系数、控制棒价值以及功率分布等堆芯关键参数的计算值与实测值之间的误差均满足工业限值的要求。Based on the conventional“two-step”scheme for the PWR fuel management,an advanced PWR fuel management software Bamboo-C has been developed by the most advanced methodologies in the reactor-physics field.Bamboo-C consists of three main functional codes:LOCUST code for the heterogeneous modeling and simulation and homogenization calculation of 2D assemblies;SPARK code for 3D core steady-state and transient analysis;and LtoS code for assembly homogenization parameter function,which links LOCUST and SPARK.Bamboo-C has all the necessary analysis functions for the fuel management and nuclear design of PWRs,mainly including the start-up physics tests,calculations of the neutron-kinetics parameters,differential and integral worth of rod cluster control assemblies(RCCAs),and power-operation following simulation.Finally,the engineering validations of Bamboo-C have been completed according to the operation data from the reactors CNP300,CNP650 and CNP1000 designed by China independently.The validation results show that the errors between the values of such key parameters of cores as critical boron concentration,temperature coefficient,RCCA worth,and power distributions,calculated by Bamboo-C,and their measured values satisfy the corresponding engineering criterion limits.
