Two-dimensional radiation transport calculations for "MONJU" shielding design

Otani, Nobuo*; not registered; not registered

Numerical results of radiation distribution in the plant of Prototype Fast Breeder Reactor "MONJU" are presented. Calculations were performed for the shielding design of "MONJU" by the two-dimensional discrete ordinate radiation transport code "DOT 3.5". For estimating MONJU shielding design parameters. 19 radiation distributions from the core to the IHX and pump room of the primary coolant system were calculated, using reactor core fissions as the source. Numerical data in this report are nominal computational results by the DOT 3.5 code and shielding design judgements are not included. The report is summarized for reference for shielding design calculations for future FBR plants.
