- Abstract
- This paper describes the iteration methods using resonance integral tables to estimate the effective resonance cross sections in heterogeneous transport lattice calculations Basically these methods have been devised to reduce an effort to convert resonance integral table into subgroup data to be used in the physical subgroup method Since these methods do not use subgroup data but only use resonance integral tables directly these methods do not include an error in converting resonance integral into subgroup data The effective resonance cross sections are estimated iteratively for each resonance nuclide through the heterogeneous fixed source calculations for the whole problem domain to obtain the background cross sections These methods have been Implemented in the transport lattice code KARMA which uses the method of characteristics (MOC) to solve the transport equation The computational results show that these iteration methods are quite promising in the practical transport lattice calculations.
