Amentum-led Joint Venture selected for $112 Million Clean-up at Four European Nuclear Research Sites

Key Terms

decommissioning technical

Decommissioning is the planned process of taking a long-lived asset or facility out of service, making it safe, removing equipment, and restoring the site for future use or closure. Investors care because it often requires large, sometimes multi-year costs and legal obligations that reduce future cash flow and create liabilities or reserve requirements on a company’s balance sheet — like budgeting to dismantle and clean up an old factory or ship.

waste management technical

The organizing of how trash and unwanted materials are collected, moved, treated, recycled and safely disposed of, including hazardous waste and materials that can be turned into new products or energy. For investors, it matters because these services are essential, often regulated and capital-intensive, and can provide steady, utility-like cash flows or be affected by changing environmental rules, recycling prices and technology—similar to owning a city's sanitation and recycling system.

radioactive waste management technical

Radioactive waste management is the set of practices for handling, treating, storing and disposing of materials that emit harmful radiation, like a secure system for disposing of toxic trash. It matters to investors because these activities carry long-term costs, legal and cleanup liabilities, and regulatory and public-safety risks that can affect a company’s finances and reputation; effective management reduces the chance of surprise expenses or shutdowns.

radiation protection technical

Radiation protection is the set of measures and equipment used to limit people’s and the environment’s exposure to harmful ionizing radiation, such as shielding, distance, time limits and monitoring devices. For investors, it matters because compliance, safety incidents and ongoing operating costs influence regulatory approvals, liability, insurance and public trust—similar to how fire alarms and sprinklers affect a building’s safety and insurance risk.

hot cells technical

Hot cells are heavily shielded, locked rooms equipped with remote-controlled tools used to handle, process and contain highly radioactive materials so people are not exposed. Think of them as a vault and robotic workbench combined for dangerous substances. For investors, hot cells signal substantial capital costs, strict regulatory oversight, ongoing safety and waste-management obligations, and potential revenue from services like medical isotope production or nuclear cleanup, all of which affect a company’s risk and cash needs.

accelerators technical

Programs that give very early-stage companies a short, intensive boost—providing small seed funding, hands-on mentoring, business training, and networking over a fixed period—to help them grow faster and prove out their products or markets. For investors, accelerators act like a scouting and sharpening camp: they increase the chance a startup becomes investable, surface promising deal flow, and can change risk and return expectations for both the startups and their backers.

CHANTILLY, Va.--(BUSINESS WIRE)-- A joint venture led by Amentum (NYSE: AMTM) has won a new framework contract as the lead decommissioning and waste management contractor for nuclear research sites in four European countries.

Pavol Stuller, Amentum’s European Development Director, and Laurent Jerrige, JRC Director for Nuclear Decommissioning, signing the contract.

Under the $112 million (€95.7 million) contract, awarded by the European Commission Joint Research Centre (JRC), the Amentum-led JV will provide decommissioning solutions to accelerate the cleanup efforts of JRC sites in Ispra (Italy), Karlsruhe (Germany), Geel (Belgium) and Petten (The Netherlands).

“Amentum’s robust track record of delivering European-funded projects on time and on budget in multiple countries, including prior experience working at JRC Ispra, made us the ideal choice for this contract,” said Loren Jones, senior vice president and head of Amentum’s Energy & Environment-International business. “We will leverage decommissioning and waste management techniques developed at the world’s most complex nuclear sites, integrating innovative solutions to complex technical and project management challenges. Additionally, our strong ties to regulatory authorities across the European Union will serve as a vital asset in ensuring success.”

For more than 60 years, the JRC sites have addressed complex challenges in areas such as nuclear decommissioning, innovation, safeguards and non-proliferation by conducting research, providing scientific advice and supporting European Union policy makers.

The decommissioning and waste management contract will cover structures such as research reactors, hot cells, accelerators, laboratories and other infrastructure where radioactive substances have been handled.

The work will be delivered by an Amentum-led joint venture with WSP Italia, supported by sub-contractors TUV Rheinland and Protection Solution SRL. The JV’s scope of work includes licensing, radioactive waste management, radiation protection, decommissioning and nuclear engineering, worksite management and safety, non-nuclear engineering, facility supervision and quality assurance.

The JRC contract has a duration of two years with three potential two-year extensions.
