Summary
Various models of large LMFBRs, based on cylindrical and hexagonal geometries, are examined in regard to application to nuclear power peaking analysis. It is shown that the general behavior of power distributions during burnup in these large reactors implies that power shaping by control rod movement is desirable for minimizing the peaking factor. Due to current limitations of available three-dimensional computer codes, one- and two-dimensional models were used to test general assumptions of power shaping. However, it is demonstrated that these models are not appropriate for more accurate power peaking analysis. Comparison of results for nuclear power peaking factors in cylindrical and hexagonal geometries shows that the use of annular rings of control poison in the cylindrical models does not provide a realistic representation of banks of control rod assemblies.
