Nuclear, biological, chemical and radiological protection equipment

Tender description

The UK Atomic Energy Authority (UKAEA) is a non departmental government body. UKAEA is involved in the design and provision of the Active Cells remote handling facility within the European Spallation Source (ESS) in Sweden. The purpose of the facility is to process and store spent activated target station components. Work on handling processes and in-cell equipment/facilities are progressing towards the detailed design phase. For individual processes and items of equipment, options need to be identified, assessed against the requirements, and developed towards a suitable design ready for manufacture. This market enquiry relates to the Lower Intrabay Door (LID) which provides radiological separation between the Maintenance Cell (MC) and Process Cell (PC). The Intrabay doors provide in-cell confinement and shielding and are therefore crucial in maintaining the internal radiological zones required for manned intervention. The exact duties and tasks for this system have not been fully defined as Active Cell operations are still being developed, however, the main requirements are shown below. 1. The LID shall fit within the pre-designed MC to PC opening. The LID shall have height of 4180mm, width of 4000mm, and thickness of 463mm. 2. The door shall slide open to allow passage of cranes and power manipulators. This will require the door to be electrically operated and interlocked. 3. The LID will have local manual open, close and recovery arrangements within the MC The solution will require design, manufacture and installation into the Active Cells facility. This PIN has been published to enable market research to commence to asses the reaction of the market to the requirement and to review available technologies. UKAEA will conduct a dialogue with the marketplace and this may result in a call for competition based on the scope of the requirement developed through the dialogue.
