Abstract: Based on transverse integration discrete ordinate equation, the relationship between transverse integrated outgoing and incoming flux was analytically obtained in this paper, and with transport nodal neutron balance equation analog to nodal diffusion method, an effective nodal discrete ordinate numerical iteration strategy was obtained. Numerical results indicate that the method given in this paper is feasible and the results are reliable. In addition, the widely used coarse mesh finite difference (CMFD) acceleration technique is adopted in nodal discrete ordinate method and provides good result.
