DISCO project focused specifically on modern spent fuel dissolution and chemistry in failed container conditions, receiving their largest single grant (EUR 470,000).
STUDSVIK NUCLEAR AB
Swedish nuclear technology firm specializing in spent fuel chemistry, materials irradiation testing, and reactor safety for fission and fusion programs.
Their core work
Studsvik Nuclear AB is a Swedish nuclear technology company specializing in nuclear fuel and materials testing, spent fuel chemistry, and reactor safety services. They provide irradiation testing, post-irradiation examination, and materials characterization for the nuclear industry. In H2020, they contributed expertise on spent fuel behavior under failure conditions (DISCO), supported the Jules Horowitz material testing reactor roadmap (JHOP2040), and participated in European fusion energy research (EUROfusion). Their work directly supports the safety case for both existing and next-generation nuclear power plants.
What they specialise in
JHOP2040 project centered on the Jules Horowitz Reactor operation plan, with keywords spanning material testing reactor, innovative nuclear materials and fuels, and irradiation experiment roadmaps.
Both DISCO (spent fuel behavior) and JHOP2040 (safety of existing and future NPPs) address nuclear safety from complementary angles — waste containment and reactor materials.
Participated as third party in EUROfusion, the flagship European fusion roadmap implementation program running from 2014 to 2022.
How they've shifted over time
Studsvik's earliest H2020 involvement (2014) was through the large EUROfusion program as a third party, suggesting an initial supporting role in fusion energy research. From 2017 onward, they shifted to direct participation in fission-focused projects — first spent fuel chemistry (DISCO, 2017) and then material testing reactor planning (JHOP2040, 2020). This progression shows a move from peripheral fusion contributions toward core fission safety and materials expertise where they hold stronger institutional knowledge.
Studsvik is consolidating around nuclear materials testing and spent fuel safety — areas where demand is growing as Europe debates new reactor builds and existing fleet life extensions.
How they like to work
Studsvik operates exclusively as a participant or third party — they have never coordinated an H2020 project, which is typical for specialized industrial contributors who provide testing facilities and technical expertise rather than driving research agendas. Despite only three projects, they have worked with 218 unique partners across 28 countries, reflecting their involvement in very large consortia (EUROfusion alone accounts for much of this network). This makes them a well-connected specialist rather than a project leader.
Through participation in large nuclear research consortia, Studsvik has connections to 218 unique partners spanning 28 countries — a remarkably broad network for just three projects. Their reach is pan-European, driven by the collaborative nature of Euratom-funded nuclear research programs.
What sets them apart
Studsvik Nuclear is one of very few private companies in Europe with deep operational expertise in both spent fuel characterization and material irradiation testing — capabilities that require specialized hot-cell facilities and decades of institutional know-how. For consortium builders, they offer something rare: an industrial partner that can perform actual nuclear material tests, not just model them. Their combination of fission safety expertise and fusion program experience also makes them a bridge between these two nuclear communities.
Highlights from their portfolio
- DISCOTheir largest funded project (EUR 470,000), addressing the critical safety question of what happens to spent fuel if geological disposal containers fail — directly relevant to every country planning nuclear waste repositories.
- JHOP2040Positions Studsvik in the operational planning of the Jules Horowitz Reactor, Europe's next major material testing reactor, ensuring access to future irradiation experiment infrastructure through 2040.
