Abstract

Abstract

A formula to calculate the multiband parameters is derived based on the multiband method.Adopting the method combining two-band and three-band, and based on the WIMSD4-69 library, a code named RESCAL is developed. The validation shows that the results of RESCAL code are well in accordance with MCNP’s, and the numerical errors meet the practical requirement.Due to the limitation of WIMSD4 69-group library and the method adopted to calculate multiband parameters, the precision of RESCAL code is highly affected by the ratio of water to uranium.
