We report on recent improvements in the theory of spectral nodal methods for the numerical solution of multidimensional discrete ordinates multiplication eigenvalue problems with anisotropic scattering in rectangular geometry. We describe an efficient numerical scheme for generating the spectrum and the elementary solutions of basic transverse-integrated SN equations for the special case of level symmetric quadratures. Generation of spectrum and elementary solutions is an important step in the (spectral) nodal strategy of estimating neutron multiplication factor and node-average power densities in nodal reactor computations. Numerical results are given to illustrate the scheme. (authors)
