Job description

On behalf of the Nuclear Decommissioning Authority, we are looking for a Field Services Engineer - Networks (Inside IR35) for a 7 month contract based in Warrington with regular expensed travel.

The Nuclear Decommissioning Authority (NDA) is a non-departmental public body created through the [1] Energy Act 2004.

We have 5 offices across the UK, in Cumbria, Dounreay, Harwell, Warrington and London. We have 17 sites including the first fleet of nuclear power stations, research centres, fuel-related facilities, and Sellafield, which has the largest radioactive inventory and the most complex facilities to decommission.

We are sponsored by the Department for Energy Security and Net Zero (DESNZ) and supported by Dounreay, Magnox, Nuclear Waste Services, Nuclear Transport Solutions and Sellafield. The Scottish government also has a governance role, working closely with DESNZ to ensure its expectations are met.

Our role is strategic - we establish the overall approach, allocate budgets, set targets and monitor progress.

We do not have a hands-on role in cleaning up our facilities. Instead, we deliver our mission through others, primarily 12 businesses.

We are responsible for:

• Decommissioning and cleaning up these nuclear facilities ensuring that all waste products, both radioactive and non-radioactive, are safely managed.
• Implementing policy on the long-term management of nuclear waste.

• Scrutinising the decommissioning plans of EDF Energy, who own the operating fleet of Advanced Gas Cooled Reactor (AGR) nuclear power stations.
