Abstract
In order to conduct nuclear analyses on neutronics issues for ITER （International Thermonuclear Experimental Reactor）, a standard three-dimensional model of the ITER reactor is being developed. The complex nuclear
analyses are conducted by MCNP/4C in three dimensions. MCAM （MCNP Auto-Modeling system） , as an implementation of the interface code between modern CAD system and MCNP, is a modeling and visualization tool which can convert a CAD model to neutronics model for MCNP and vice versa. This paper presents the application of MCAM to modify ITER 3-D neutronics model, which include blanket segmentation update, incorporation of fine structures of inboard blanket and the model extension from 20° to 40° in toroidal direction
