Abstract
Three dimensional (3-D) virtual reality can be an effective tool for education, training and improved human performance in nuclear engineering applications. This technology can be used to model and simulate nuclear facilities with the help of custom-made packages and/or using well-known programming languages. We earlier reported the development of nuclear-specific virtual reality models using a well known game engine. This paper introduces some new features and scenarios which were developed for the models of interest. Specifically, some of the built-in features of the game engine are exploited to add nuclear-specific applications and to enhance interactivity. With this technology, Nuclear Power Plant (NPP) personnel and first responders can "play" and, hence, experience and emulate the operational and emergency scenarios of a plant through these specifically developed interactive and 3-D graphical models of nuclear facilities.
