A new analytic method for the solution of two-dimensional (r,z) multigroup multiregion problems is described. The solutions are gained by expanding each of the fluxes in a double series of eigerfunctions valid over the entire reactor, without the requirement that fluxes and currents be continuous at the interfaces in the conventional nuclear reactor theory. The eigenfunctions used are solutions of a two-dimensional Helmholtz equation that vanish at the outer boundary of the reactor. Finally, by applying this theory to a particular reactor, in which a cylindrical core is surrounded by cylindrical reflector symmetrically, the relations between the eigenvalue of the criticality equation and the number of modes of neutron flux are examined.
