Abstract

A low-level radioactive-waste shipping vessel in which as auch as 3000 radwaste drums were loaded was supposed in the study, and the gamma-ray dose rate distributions in the shipping vessel were estiaated by using the Monte Carlo coupling code systea MORSE-CG/ RADWASTE-VESSEL. The calculated results from the MORSE-CG/ RADWASTE-VESSEL code system were compared with other calculations by the point kernel codes, SPAN, QADCG, QAD-CG·GP, and QAD-CG with the attenuation cross sections. After comparison with each calculation, satisfactory agreeaent was obtained except a few dose points.
