Multichannel Flux Synthesis

In Part A a procedure is described for calculating neutron fluxes at nodes of a three dimensional grid with few points in planes perpendicular to a selected axis. Difference equations relating fluxes within each plane are determined in advance from detailed two dimensional studies. This “multichannel synthesis” model may be used for parameter studies and dynamic analysis. Comparison of a representative calculation with results of a detailed three-dimensional computation is given in Part B.
