Use of virtual reality on radioactive waste deposits development
Palavras-chave:
Virtual reality, Radiation, Radioactive wasteResumo
One of the biggest challenges in the nuclear area are still nuclear radioactive waste generated in the
various applications of this energy, all these wastes are stored in tanks that are frequently monitored and
restructured to better utilization of the same. Considering the routine process of this work and due to the
seriousness of the issue, are very useful methods and techniques to predict the radiation dose absorbed
by the worker in performing this task. One of the possible ways to accomplish advance planning of these
activities is through the use of computer simulators. In this context, this paper presents a methodology
based on virtual reality, in order to develop a radioactive waste virtual deposit in order to enable simulations
of virtual relocation in these deposits. With the development of deposit becomes possible to
simulate virtual/train allocation and reallocation of low and medium level waste materials, since the
possibility of displacement for virtual objects and dynamic calculation of the radiation rate in this
environment. Through virtual simulations is possible to know the dose accumulated by virtual person in
procedures performed in the virtual environment, since each virtual object in the tank is a source of
radiation. As a first case study was modeled virtually the nuclear waste repository located at the Instituto
de Engenharia Nuclear e IEN/CNEN. This first model was evaluated according to the realism of the
environment and computational radiation modeling. The results for the modeling of the virtual environment
and the modeling of radiation, proved satisfactory, as the good approach to be compared with
the real environment. Therefore this research contributes to show the great potential of virtual simulation
tools in the training operation of nuclear facilities, avoiding physical immersion in higher levels
radiation.
