Amentum, a US defence and engineering firm, announced on January 27, 2026 that it had secured UK nuclear power plants contracts with EDF valued at up to $730 million (about ยฃ540 million). The agreements cover engineering and technical services for Britainโs existing nuclear power stations as well as the new Hinkley Point C plant.
The long-term contracts will see more than 1,000 UK-based specialists deployed to support reactor operations, safety, testing and project management across EDFโs fleet. Amentum said it already has around 300 staff working at Hinkley Point C under an existing agreement and will expand its workforce as the plant moves closer to operation. The company currently employs more than 6,000 people in Britain and acts as a lead delivery partner for major projects including Hinkley Point C and Sizewell C.
The agreements cover ten-year performance partnerships for Hinkley Point C and EDFโs operational plants, as well as a five-year reactor management contract which includes reactor operations, life extension and preparation for decommissioning. As part of the agreements, Amentum will offer engineering and technical services. Its earlier 2015 โLifetime Enterprise Agreementโ with EDF already contributed to extending the operational lives of the UKโs advanced gas-cooled reactors.
Company executives described the deals as a strong endorsement of Amentumโs nuclear capabilities. Loren Jones, Amentumโs senior vice-president for energy, said the firmโs โexpertise in gigawatt reactor operational support and life extensionโ makes it โthe ideal partner for EDFโ. Mark Whitney, president of Amentumโs Energy & Environment business, said the contracts โbuild on Amentumโsโฆposition as a lead strategic partner to EDFโ.
Beyond civilian power generation, the UK nuclear power plants contracts also align with wider national security priorities. Amentumโs UK operations provide safety advice and technology services for the Royal Navyโs nuclear submarines and support the Atomic Weapons Establishment, contributing to the countryโs continuous at-sea nuclear deterrent.
Amentum chief executive John Heller said that โthe energy resilience and national security of both nations depend on continued leadership and advances in energy and technologyโ. The contracts are expected to strengthen the UKโs clean energy infrastructure while sustaining the skilled workforce and technical expertise required for long-term energy security.
