TL;DR: In this article, a three-dimensional variational nodal method (VNM) is presented for core calculations without fuel-moderator homogenization and the nodal functional is presented.

TL;DR: In this paper, the Partitioned-Matrix (PM) technique was extended to the Fission-Source (FS) iteration to accelerate the flux convergence by using low-order flux moments also.

TL;DR: NECP-Hydra is a three-dimensional high-performance parallel code for reactor core analysis and radiation shielding calculation that achieves both high accuracy and efficiency throughout these verifications, and this paper summarizes its main features and carries out some verifications.

TL;DR: In this paper, two heterogeneous nodal methods based on the Variational Nodal Method (VNM) with diffusion approximation in three-dimensional Cartesian geometry are investigated with a code named Violet-Het3D for PWR control rod cusping effect and pin-by-pin calculation.

TL;DR: Hybrid parallelization of the three-dimensional variational nodal method (VNM) for pin-resolved neutron transport calculations is presented in this paper, where sets of node-energy response and associated matrices are assigned evenly to the available set of MPI processors and OpenMP is further employed to parallelize integrations over angle in the response matrix formation.
