The European Spallation Source (ESS) is a multi-disciplinary research facility which will be the world’s most powerful pulsed neutron source. A critical component of ESS will be a facility for handling radioactive waste and preparing it for safe disposal. Safe disposal of ESS waste requires the dexterous tele-manipulation of large, highly activated payloads in a shielded chamber: a hot cell. Traditionally hot cells are built with lead glass windows to allow direct observation by operators. However, as the complexity and scale of required handling operations increases, the restrictions imposed by such windows become problematic, motivating the development of hot cells without any windows. RACE is building on its experience operating the Joint European Torus (JET) remote handling system to develop a windowless hot cell for the ESS Active Cells Facility (ACF), featuring a fully integrated remote handling system and a state-of-the-art synthetic viewing system. What will follow is a brief background into the current state of the art in control systems for Remote Handling, followed by the proposed design of the ESS Synthetic Viewing system, concluded with a short discussion.
