Fuel retrieval and transportation
Substantial work has been undertaken historically at Dounreay, to explore the best means to manage Miscellaneous Irradiated Fuel (MIF) materials, since reprocessing operations on the Dounreay site were ceased in 1996.
As a result, it was previously decided that MIF material which remain unprocessed could be stored, in the interim, at the Dounreay site until an alternative UK storage or disposal facility was made available. Since then, the strategic position has changed in accordance with UK Government policy and in 2013 the Nuclear Decommissioning Authority (NDA) announced its most credible and preferred options for long-term management of the MIF materials which was (and still is) to move the MIF material to the Sellafield site. The main aim of the IF Programme is to remove, package and transport Dounreay MIF materials to Sellafield to enable the material to be safely managed over the longer term.
Tenet Consultants were engaged by the Principal Designers (Cavendish Nuclear), to advise and assist with the production of Scheme Design Deliverables for the Electrical and Mechanical works of this challenging Mechanical Handling Project.
To meet the requirements of the project, Tenet Engineers have used their vast experience and skill sets, to progress the following technical areas:
Mechanical Activities
- Production of Mechanical Scheme Design Deliverables for the Transport Flasks, Import / Export Bogie, Lid Lift Machine.
CE&I Activities
- Review of Concept design to identify gaps and areas of concern.
- Production of Control System deliverables, such as Control Philosophy, S&IDDs, SCADA FDS, Fuel Tracking System Spec.
- Production of RSI (Radiometrics and Special Instruments) Design, including Layouts and Cable Routing.
- Production of Building Services Deliverables such as Load & Cable Schedules, CCTV Specification and Layouts & Cable Calculations.
Associated project deliverables include:
- General arrangement and detail drawings
- Schedules and Progress Reports
Joining the project at a critical time of its lifecycle, with challenging cost and budget constraints, Tenet negotiated a steep project learning curve in a short period of time, hitting the ground running, to provide a seamless extension to our clients engineering capabilities, whilst building and maintaining relationships with our client’s engineers and vendors both in person and remotely across the Microsoft Teams platform.
Due to the remote nature of the facility and the distributed client team, Tenet was key in providing an integrated design solution with CE&I working closely with the Mechanical team in house and the clients Engineering and Radiometrics capability teams to deliver a full scheme design package enabling robustly underpinned future phases of work.
Tenet provided Mechanical and CE&I resources at levels from Apprentice up to Engineering Manager in order to meet client requirements, using Suitably Qualified and Experienced persons (SQEP) to ensure accuracy, efficiency, safety and integrity of designs and information.
By engaging Tenet, the client was provided with the compliant information packages and design deliverables required to meet the goals of delivering a robust Scheme Design for the facility.
Tenet generated, reviewed, and delivered the information required for facility scheme design, whilst building and maintaining strong working relationships with our client and their customer.
Tenet provided additional value to our client by undertaking independent reviews of project produced documents, identifying areas where additional information was required to progress the Scheme Design, and carrying out the engineering tasks required to complete the information packs.
