Abstract :
A nodal method based upon the least squares minimization technique. has been
developed for solving the neutron transport equation using spherical harmonics
approximation in 3-dimensional Cartesian coordinates. The second order form of the
spherical harmonic differential equations based upon the even parity form of the transport
equation are utilized. The governing equations are casted into a set of elliptic type
differential equations for which the coefficients can be generated for any spherical
harmonics approximation order automatically. The coeffICients of the mixed type boundary
conditiions are obtained through recurrence relationships for any order as well. The
approximation order to be used in the nodes can vary according to the physics of the
problem and determined by the computer code.
