摘要：

The multiple reciprocity method has been applied to one-group fission neutron source iteration problems. The domain integral related to the fission neutron source in the mth source iteration stage is transformed into a series of m - 1 boundary integrals. These integrals require the zero order to the m - 1 order fundamental solutions and the boundary neutron fluxes and currents calculated in the previous m - 1 source iterations. Results obtained in a simple test calculation indicate that the source iteration based on the present technique converges rapidly to the desired eigenvalue as long as a certain condition is satisfied.
