A transmission probability method for hexagonal geometry implemented in the program TPHEX is described briefly. This program was developed for the calculation of neutron flux distributions in hexagonal light water reactor fuel assemblies. The accuracy appears to be superior to diffusion theory, and the computation time is shorter than that of the collision probability method.
