摘要
压水堆堆芯Pin-by-pin燃料管理计算程序NECP-Bamboo2.0,利用广义等效均匀化理论实现栅元均匀化计算,采用指数函数展开节块SP3方法进行全堆芯中子输运计算,采用多物理并行计算技术实现了三维全堆芯的核-热-燃耗紧耦合高性能计算。本文利用大型压水堆BEAVRS基准题验证该程序计算的精确性。验证结果表明:NECP-Bamboo2.0具有较高的计算精度,能满足于工程需求。
PWR-core pin-by-pin fuel management calculation code NECP-Bamboo2.0 employs the Generalized Equivalence Theory to homogenize each pin-cell within the lattice, and employs the Exponential Function Expansion Nodal SP3 method to fulfill the three-dimensional multi-group whole-core neutronics calculation. A whole-core multi-physics parallelization algorithm is designed to carry out the tight coupling between neutronics, thermal hydraulics and depletion calculations. The BEAVRS problem was employed to verify its accuracy. Numerical results demonstrate its good accuracy and flexibility to engineering problems.
