Design of a virtual engineering environment and an evaluation of an operator’s behavior

The purpose of this study is to provide a basis for a minimization of a worker´s dose during dismantling activities. In the present study, we proposed methods for identifying an existence of radioactivity which is contained in dismantling objects and for evaluating a worker´s dose under a virtual dismantling environment. As a basic study to minimize a radiation exposure, we calculated the exposure dose by using the MCNP-4C as a worker dismantled an object in a radiation field. Secondly, we implemented animation and simulation modules to simulate a worker´s dose in a real-time. The radiation field of the thermal column door was visualized three dimensionally by using the radiation dose that was calculated by the code. The results show that it can simulate various kinds of dismantling activities and simultaneously view the exposure dose level in a real-time according to dismantling activities through an animation and simulation.
