Abstract: per presents some preliminary work on the applications of multi-grid method for solving the 2D reactor diffusion Equations. We used the multi-grid method with V-cycle and W-cycle for solving a model problem and comparied the results by SOR. Numerical results showed that the multi-grid method with W-cycle is the best. It is faster four time than the SOR.

Key words: nuclear reactor, multi-gird method, SOR
