Description

In this paper, a new 2D/1D transport code NECP-X is developed based on the parallel MOC method. In this paper, (i) energy-group-sweeping-inside strategy is used as the default choice after balancing sweeping efficiency and iteration-format-degeneration. (ii) the negative source/flux problem caused by energy-group-sweep-inside strategy is analyzed and solved by temporarily, (iii) two CMFD solvers based on odCMFD are developed and the solver with PETSc math library found to be more efficient for large scale cases, (iv) preliminary multi-level parallel is implemented, and the individual parallel tests show the satisfied parallel efficiency for energy, space, angle and ray parallelization.
