Nuclear Reactor as Stiff System. III. Quasi Asymptotic Method and Spectral Problem. Numerical Experiments

This preprint contains the results of numerical experiments. They illustrate the effectiveness of two new algorithms. The first of them is quasi asymptotic method of integration of the equations of the neutron fields dynamics. It uses the solution of the generalized main eigenvalue problem. The second is an iterative method of solving the main eigenvalue problem. It is based on the simultaneous (for all energetic groups) relaxation process and multigrid acceleration of the convergence speed.
