Amentum Expands UK Nuclear Energy Specialist Services Portfolio with $730 Million Major Contracts Win

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.

CHANTILLY, Va.--(BUSINESS WIRE)-- Amentum (NYSE: AMTM) has won a suite of new contracts from Électricité de France (EDF) worth up to $730 million (£540 million), expanding the critical solutions it provides for the UK’s existing nuclear reactors as well as the construction of a new gigawatt power station at Hinkley Point.

Loren Jones, senior vice president and head of Amentum’s Energy & Environment-International business, said: “Amentum’s expertise in gigawatt reactor operational support and life extension makes it the ideal partner for EDF, one of the world’s largest nuclear utilities.

“This award advances our strategy to accelerate the growth of our nuclear energy business in line with the opportunities being created by the worldwide nuclear resurgence.

“Amentum will deploy the skills and experience of more than 1,000 UK-based specialists to provide the full breadth of nuclear skills, solutions, and products essential to the continued operation and life extension of the UK’s existing nuclear fleet.

“A further 300 Amentum colleagues are already delivering multi-disciplinary roles across Hinkley Point C under the Professional Services Agreement. We expect this number to grow as these new contracts mature, strengthening our position to support long-term operations once the reactors come online.”

Amentum has a Lifetime Enterprise Agreement with EDF, signed in 2015, to provide strategic, long-term technical solutions for EDF's UK nuclear fleet including licensing, design and construction, modeling and analysis solutions, and laboratory and engineering test facilities. This work has enabled EDF to achieve an aggregate 38 years of life extension across the seven advanced gas-cooled reactor stations.

Mark Whitney, president of Amentum’s Energy & Environment business, added: “These new contracts build on Amentum’s differentiated position as a lead strategic partner to EDF and advance an immensely productive business relationship that dates back many decades.”

The newly awarded contracts comprise: ten-year Professional Services Agreement frameworks with Hinkley Point C; EDF Nuclear Operations and EDF Nuclear Services to support the Hinkley Point C new build programme, operating stations and their engineering capability hub; and a five-year Project Management Resources framework to support station operations, life extension and preparation for decommissioning.
