[2F07] Development of collision probability method based on Mesh to Mesh computation (8)

Angular flux distribution in IC boundary of 2D transport calculation

*Tetsuo Matsumura1 (1. CRIEPI)

Keywords:transport calculation, collision probability, escape probability

As collision probability method requires numerical calculation time, easy collision probability calculation method with shorter calculation time is under development.

By combining with the collision probability of the uniform XY geometry acquired from the table of escape probability of a rectangle cell, and the Interface Current (IC) method, development of the transportation calculation technique of general-purpose XY geometry is expectable. As IC method requites detailed dealing with the angle distribution in the boundary, I examined the approximating method of angle distribution in the boundary using the collision probability of the uniform XY geometry.
