Development of animation and simulation module for evaluation of Worker's dose

A study to visualize the radioactivity distribution in a dismantling facility that was contaminated by the radiation from the exposure room at KRR 2(Korean Research Reactor TRIGA MARK III) was carried out to improve worker safety and decommissioning productivity. As a basic study to minimize a radiation exposure, the worker exposure dose was calculated using the MCNP-4C (Monte Carlo N-Particle-4C). Secondly, an animation and simulation module was implemented to simulate a worker's real-time dose. The results show that various kinds of dismantling activities can be simulated while simultaneously viewing the exposure dose in a real-time according to the selected scenario for the animation. Current work is focus on exploring the evaluation of a worker's dose in a virtual dismantling area by using computer graphics. Future work will seek an optimization of the major parameters that directly affect a personnel exposure dose rate. This will enable a worker who is engaged in a hazardous area to attain an improve safety by decreasing exposure when applied as a useful tool to dismantle nuclear facilities. (authors)
