/image-library/Our-stories/Nagra/Nagra-Hero-Image.v2.resizedjpg.x0544840f.jpg

NAGRA's Nikitas Diomidis explains how TWI helped to develop radioactive waste disposal canisters.

01

NAGRA (National Cooperative for the Disposal of Radioactive Waste) is a Swiss company founded in 1972 with the responsibility for the safe disposal of all radioactive waste in Switzerland. Nikitas Diomidis, the Section Head of Materials Performance at NAGRA, spoke about how working with TWI has helped them achieve their goals.

TWI has been working with NAGRA since 2010 to develop disposal canisters for spent nuclear fuel and vitrified high-level waste. With a focus on engineered barriers to ensure long-term safety, the collaborative work has made a significant difference to meeting the challenges of providing a waste disposal solution designed to last for several thousand years.

TWI’s experience has aided the quality of the various waste disposal canister concepts being developed by NAGRA. This comes, in part, from TWI’s unique ability to bring together a team with various areas of expertise, including welding, materials, inspection and structural analysis. This joined-up approach allows TWI and NAGRA to assess the design of waste disposal canisters from multiple angles to create a complete solution.

As Nikitas explained, the collaboration between TWI and NAGRA has proven successful over the last decade and looks set to continue for several years into the future.

TWI has a long history of assisting the nuclear industry and is a trusted partner for developing Small Modular Reactors (SMR).
