The contract would be worth up to €4m over four-year period.

Under the contract, Amec will provide engineering support based on experience of nuclear installation in-service inspection for developing the maintainability and inspectability of the ITER structures, systems, and components during their design.

The contract scope includes critical complex including the hot cell, where irradiated components are dismantled and treated, and the 3,850t Cryostat high-vacuum pressure chamber.

Amec will also be responsible for analyzing reliability and control costs as well as perform virtual and physical mock-ups to test procedures, and produce maintenance documentation.

Amec Foster Wheeler Clean Energy business consultancy vice-president Greg Willetts said: "This contract win represents another step forward in our aspiration to play a major role across the ITER project.

"It underlines our leading expertise in nuclear remote handling and robotics and highlights the key role we are playing in developing future nuclear technologies while continuing to support the existing nuclear fission power industry."

Amec said that the contract will strengthen its role at ITER, a 35-nation project to build an experimental fusion reactor.

A joint venture led by Amec Foster Wheeler secured a €70m, seven-year contract in May 2015 to conduct all activities ranging from design, manufacturing, factory testing, delivery, on-site integration, commissioning and final acceptance tests for ITER’s neutral beam remote handling system.

The project aims to demonstrate nuclear fusion as a viable future energy source.

Planned to commence operations in 2020, the ITER project involves participation from the European Union (EU), Russia, Korea, China, India, among others.
