Abstract
The hot cell building is a part of the hot cell complex which is located to the north of the main ITER tokamak building. It would provide a controlled area for the preparation, transfer and repair-refurbishment of the in-vessel parts of the tokamak machine. During transfer of the activated parts and plasma operation, high radiation would be produced. For safe operation and maintenance of nuclear devices, it is very important to predict the dose rate distribution caused by transferring the components. This paper describes the study of the dose distribution in the hot cell building. A whole calculation model based on existing MCNP calculation models was built by multi-physics coupling analysis modeling program and then used to calculate the dose map using MCNP with sources defined according to previous calculation results. The thickness of shielding doors was then optimized according to the gamma dose before the doors and gamma dose attenuation within a concrete door.
