Abstract:
The steady-state neutron transport equation for slab geometry is expanded in Legendre polynomials. The expansion is truncated after the third term P sub 2 equations and then is modified in an attempt to reduce the truncation error. The resulting equations are, for many problems, a better approximation to the neutron transport equation than the P sub 2 equations or the standard diffusion equations. The method is extended to two and three dimensions by a simplified form of the spherical expansion to the neutron transport equation. Sample results are given. Author
