“…Realistic visualisation of the planned work protocols and risks can contribute to establishing appropriate situation awareness and understanding of the assigned tasks for the field operators involved [17,18]. The technology has been found to be superior to paper-based briefing [18], since every work scenario is associated with a physical 3D environment in which human activities, radiation, and other sources of danger have a dynamic 3D nature. The 3D projection technology enables stereoscopic viewing for teams of stakeholders, which typically results in more rapid depth perception than 2D projection, and can therefore be useful for relatively short procedures (less than 30 minutes), while 2D projection is more comfortable to view for longer periods of time [19].…”

There is an increasing international focus on the need to optimise decommissioning strategies, driven by the anticipation of high costs and major effort for the decommissioning of nuclear facilities in the coming decades. The goals are to control and mitigate costs and negative impacts on workers, the general public, and the environment. The methods presently employed for many decommissioning tasks do not apply the latest advancements of science and technology. Therefore, there is growing interest in research and development into the adoption of novel techniques for improving safety, reducing costs, and increasing transparency. This paper provides a comprehensive overview of the authors' results from investigating how current and emerging technologies can be applied to enhance the international decommissioning strategy, focussing in particular on three-dimensional simulation, virtual reality, advanced user interfaces, mobile and wearable devices, and geographical information systems. Our results demonstrate that emerging technologies have great potential for supporting adoption of new instrumentation, improving data and knowledge management, optimising project plans, briefing and training field operators, and for communication, surveillance, and education in general.

Commission V, WG V/4 KEY WORDS:as-built data, terrestrial laser scanner, panoramic images, CAD models, industrial applications, large scale scanning surveys ABSTRACT:As-built CAD data reconstructed from Terrestrial Laser Scanner (TLS) data are used for more than two decades by Electricité de France (EDF) to prepare maintenance operations in its facilities. But today, the big picture is renewed: "as-built virtual reality" must address a huge scale-up to provide data to an increasing number of applications. In this paper, we first present a wide multi-sensor multi-purpose scanning campaign performed in a 10 floor building of a power plant in 2013: 1083 TLS stations (about 40.10 9 3D points referenced under a 2 cm tolerance) and 1025 RGB panoramic images (340.10 6 pixels per point of view). As expected, this very large survey of high precision measurements in a complex environment stressed sensors and tools that were developed for more favourable conditions and smaller data sets. The whole survey process (tools and methods used from acquisition and processing to CAD reconstruction) underwent a detailed follow-up in order to state on the locks to a possible generalization to other buildings. Based on these recent feedbacks, we have highlighted some of these current bottlenecks in this paper: sensors denoising, automation in processes, data validation tools improvements, standardization of formats and (meta-) data structures. * Corresponding author. CONTEXT AND CONTRIBUTIONSIndustrial installations need constant maintenance operations to keep performance and safety at their highest levels. In the last decades, as-built data (Terrestrial Laser Scanner data -TLS-, asbuilt CAD models reconstructed form scans, panoramic images) have proven their efficiency for preparing decision and executing several maintenance operations. But today, the big picture is renewed: "as-built virtual reality" must address a huge scale-up to provide all the current and incoming applications that rely on these data sets. For example, at Electricité de France (EDF), owner and operator in France of 58 nuclear power stations, many use cases have been recently developed for maintenance of the plants using as-built virtual reality. From a few areas, many buildings will soon be digitized. Surveyors on field switch from "modest" surveys with 50-100 stations to very large surveys with at least 1000 stations. Computers, software, storage and networks change from handling Megabytes to hundreds of Terabytes of data: this is no more business as usual.In this context, through this paper, our contributions are the following: depicting the current trends of industrial close-range as-built data creation for industrial uses at EDF, by describing real cases, scales and issues,  sharing feedbacks from a first wide multi-data closerange acquisition campaign (1083 TLS stations, 1025High Resolution panoramas, 2D maps and 3D models as-built reconstruction and processing),  highlighting short and medium terms challenges of close-range acquisition tools and methods...

EXECUTIVE SUMMARYAdvances in immersive visualization technology allow for the creation of computergenerated, three-dimensional virtual reality environments. Through the use of a CAVE system, a small group of users can be physically immersed within a full-scale virtual mockup generated from standard Computer-Aided Design (CAD) data. These virtual mockups can be used to provide an effective 1:1 scale review of a space for a small group of users, or to virtually perform human-in-the-loop task simulations to enable improved insight into arrangement, manufacturing, and operational issues.Using distributed interactive simulation technology, virtual environments hosted on different computer systems can communicate over networks in near real-time. This capability permits, for example, a workstation networked to a CAVE system to be configured to remotely observe the activities of a user within the CAVE. This capability can enable an effective collaboration between a larger group of users than can actually be immersed within the CAVE itself.The objective of this five-task project is to demonstrate the feasibility and effectiveness of using full-scale virtual reality simulation in the design, construction, and maintenance of future nuclear power plants. The project will test the suitability of immersive virtual reality technology to aid engineers in the design of the next generation nuclear power plant and to evaluate potential cost reductions that can be realized by optimization of installation and construction sequences. The intent is to see if this type of information technology can be used in capacities similar to those currently filled by full-scale physical mockups.Much of the development of the virtual mockup has taken place at Penn State ARL's SEA Lab facility. The SEA Lab equipment includes a five-sided CAVE in which the computer-generated images completely surround the user. A number of tools allow the user to view and interact with the virtual mockup. Active-stereo glasses, worn by users, allow three-dimensional, stereoscopic images to be viewed. A motion tracking system tracks the user's position in the virtual world. The user is able to navigate freely through the world using a mouse-like device. The wand device facilitates interaction with objects within the image. Together these tools provide the user with a believable virtual reality experience.While previous work demonstrated that virtual reality can be used in training applications for hazardous work environments, this project aims to extend the previous body of knowledge to include the use of full-scale mockups for NPP training activities. Four virtual mockups were developed during this study, which model training mockups at Limerick Generating Station, Susquehanna Steam Electric Station, and the yet-to-be-built AP1000. The mockups were used to test the technology's applicability to common training tasks in the nuclear industry. Of these tasks, the technology, in its current state, appears to be best suited for pre-job walkdowns, equipment placement acti...
