Used THOMAS SWAN Epitor / Epison II #9073805 for sale

THOMAS SWAN Epitor / Epison II is a nuclear reactor developed by the company THOMAS SWAN Limited, a British-based engineering design, manufacturing, and research and development firm. It consists of a vertical stainless-steel pressure vessel, arranged in a silo-type configuration, with a total power output of 6.8 MWth. The chamber is lined with beryllium oxide and filled with helium gas at an appropriate pressure to maintain the required thermal hydraulic conditions. Within the pressure vessel, fuel elements in a variety of shapes to provide different levels of enrichment are disposed in a radial outward arrangement from the core. Control rod assembly is positioned within the core to facilitate the reactive control and shut-down scram. The external configuration of the reactor comprises a core structure, a primary cooling equipment, a secondary cooling system and a containment structure. The vessel is constantly cooled internally by one of two closed-loop water-cooling systems. The primary cooling unit, or 'hot loop,' operates with a flow of cooling water at a temperature of up to 300°C and utilizes a heavy water moderator. This coolant is circulated through the core, with the required pressure being regulated by a primary solution circuit pump. The secondary cooling machine, or 'cold loop,' is engineered to reduce the temperature of the water flowing through the reactor chamber by passing it through a heat exchanger, then a series of chillers and cooling coils outside the reactor vessel. Heat generated by the nuclear reaction is then transferred to the outside environment. The containment structure is a vitrified vessel made of reinforced concrete. It houses the reactor internals and its components, such as the control rod assemblies, shielding and external piping. The reactor pressure vessel is sealed within the concrete containment vessel and supported with external steel columns. A tool of radiation monitors and leak detectors is employed to detect and alert of any unforeseen changes. Epitor / Epison II is a reliable, efficient and safe reactor design that can be operated in a wide range of situations and nuclear power generation projects. Its superior design allows for maximum flexibility and optimization over extended periods of time. The reactor is designed to require minimal maintenance, leading to reduced operating costs and increased economic viability. Furthermore, it is designed to have a fast startup period, making it suitable for a wide variety of sites.
