Description
A HEXAB-II-3OK implementation of a two step iterative method, based on Chebyshev polynomials is described. The acceleration of the outer iteration convergence is illustrated in three test problems. The results for WWER-1000 with 5710 points in space and four neutron groups indicate that significant gains in efficiency can be achieved by using a priori information for the eigen-spectrum and by more rational programming
