Tender description

The Authority has a requirement for the Design and Manufacture of a Double Bean Box Vacuum Vessel. The UK Atomic Energy Authority is a non-departmental government body carrying out research into the potential of nuclear fusion as a future source of energy. The Authority has a requirement for a vacuum vessel. The vessel shall be of welded stainless steel construction. Its purpose is to house, mount and align internal and external components, while providing feedthroughs for required services. Key requirements: — the vessel must be designed to recognised ASME or European pressure vessel code as far as practicable, — the vessel must be ultra-high vacuum compatible, — mass of vessel body cannot exceed 14 500 kg, — mass of vessel lid cannot exceed 10 000 kg, — mounting points must be achieved with high degree of positioning accuracy and allow for adjustment, — deflection must be minimised when under vacuum. The scope of work for the design and build of the vacuum vessel could include (but is not limited to): detail design work encompassing regular progress meetings, stress analysis and design substantiation, preparation for detail design review, CAD models, manufacturing drawings including welding details, quality documentation, procurement specification, manufacture of all system components to procurement specification including jigs and fixtures, inspection and factory acceptance testing of all components, cleaning to UHV standards, delivery to site. This PIN has been published to enable market research to commence to assess the reaction of the market to the proposed requirement and review available technologies. The Authority will conduct a dialogue with the marketplace. This may result in a call for competition based on the content of the requirement achieved through the dialogue.
