Assystem Selected for JET Fusion Facility Decommissioning Framework

Assystem has secured a position on the UK Atomic Energy Authority's (UKAEA) Joint European Torus (JET) Decommissioning and Repurposing (JDR) multi-supplier Management Support Framework. The four-year agreement covers the next stage of the facility's operational life.

The 40-year operation of the JET fusion experiment recently concluded, having achieved numerous world records in fusion science research. The JDR programme now marks the next phase, scheduled to run until approximately 2040. This programme will support current and future fusion initiatives both within the UK and internationally.

Through the JDR Management Support Framework, Assystem will provide multidisciplinary expertise to UKAEA's Tier 1 management organisation, enabling leadership and delivery of the associated programme of works. Initial support will include site-based technical leadership for safe, compliant, and efficient engineering solutions for nuclear decommissioning through pre-construction and construction phases. Assystem will also provide digital expertise for the design and governance of document and information management solutions.

With 20 years of experience on global fusion programmes such as ITER, Assystem has established itself as a global partner to the fusion energy industry. The company has played a strategic role in shaping the UK and international fusion ecosystem, bridging the gap between research and industrialisation. Its expertise in tritium engineering, nuclear safety, remote handling, and systems integration aligns directly with the UK's technical priorities.
