Virtual Reality based System for Nuclear Safeguards Applications

Many Nuclear Safeguards applications can benefit from interactive design and simulation tools to be used by planners and inspectors at headquarters. Virtual Reality technologies provide the capability to create accurate, realistic and immersive environments, as well as create ¿objects¿ ¿ representing equipment, measurement devices and radiation sources, with specific properties and behaviours. To be adapted to Safeguards, applications need to reflect the equipment, functions (including the laws of Physics) and procedures that are ultimately used in the field. The paper presents the development of a virtual reality based prototype aimed at simulating the selection, installation, configuration and usage of Safeguards equipment. Examples include surveillance cameras and radiation detection equipment. Design and simulation are achieved by using these devices in realistic environments, including the presence of virtual radioactive sources. Application scenarios include: (a) the design of a Safeguards approach for a given installation; (b) the determination of the most appropriate location to install equipment (e.g., surveillance cameras); (c) the interactive evaluation of equipment¿s effectiveness for specific applications and scenarios; (d) training on the use of specific equipment ¿ e.g., using radiation detection equipment. The paper details an application involving the simulation of surveillance cameras for spent fuel storage areas. The system enables the interactive selection of the location (i.e., position and orientation) of cameras as well as their optical setup ¿ lens selection. In a second phase, radiation detectors are implemented. The user is presented with an interface replicating the real instrument. The user can then train his/her detection skills when using the detection equipment, as well as follow the best practices related to the task.
