Abstract

Highlights: Rotational plane slicing (RPS) method is proposed for 3D neutron transport analysis. 3D structure is sliced vertically along the characteristic rays. A set of vertical planes (2D problems) are solved to get 3D solution. As a 2D problem solver for rectangular cell, LC and DD SN schemes are mixed-used. Abstract: The rotational plane slicing (RPS) method is proposed for 3-D whole-core neutron transport calculation. This method takes a view of the 3-D structure with a set of vertical planes that are obtained by slicing along the characteristic lines. In a 3-D structure with a simple axial configuration, the sliced planes consist of rectangular cells. Each sliced plane is then analyzed quite easily with a 2-D transport discrete ordinate solver. Several numerical tests are performed and the results indicate that the RPS method reproduces the reference solution with good accuracy.
