2. Mechanical Engineering
Assystem Energy and Nuclear offers a world class mechanical engineering design service utilising a
broad base of in-house skills relevant to the world energy market. Specialist knowledge developed
since 1966 across a multi disciplined team, allows Assystem Energy and Nuclear to be a “one stop
shop” for the delivery of cost effective technical solutions to clients for all phases of the project.
In operations such as waste removal or decommissioning tasks,
where the mechanical handling of nuclear waste is involved,
Assystem Energy and Nuclear is able to provide innovative
engineered solutions through the design and supply of equipment to
safely cut, remove, categorise and „containerise‟ the waste. Remotely
operated vehicles, special shielded transfer enclosures, container
handling and transportation, all feature prominently in the solutions
provided to our customers to date.
Operating in the nuclear industry Assystem Energy and Nuclear
have designed, assembled, tested, commissioned, managed and
decommissioned a large variety of machines and systems for
mechanical handling of hazardous or delicate materials and
inspection and repair of facilities.
