Abstract

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.
