Project Manager - Nuclear Fabrication and Modular Construction

Originally named, Great British Nuclear, Great British Energy - Nuclear is an arm’s length body of the Department for Energy Security and Net Zero, dedicated to supporting the development and deployment of new nuclear technologies in Great Britain. We play a crucial role in advancing nuclear new build, ensuring the UK’s energy security and achieving net-zero carbon emissions. Great British Energy - Nuclear focuses on fostering innovation, facilitating investment, and coordinating efforts across the nuclear industry to build a resilient and sustainable energy future.

Great British Energy - Nuclear’s first step was to start the technology selection process for Small Modular Reactors (SMRs) in 2023. SMRs can potentially be quicker to deploy and less expensive to build than traditional nuclear power plants because they are smaller, have factory based modular manufacturing and more flexible deployment options. In June 2025, Great British Energy - Nuclear announced that Rolls‑Royce SMR had been selected as the preferred bidder to build the UK’s first SMRs, following a technology selection process that began in 2023.

Great British Energy - Nuclear is aiming to deliver fast, based on a supportive and collaborative culture which values equality and diversity and creates an inclusive workplace. We draw on deep nuclear expertise – our Executive Committee has over 100 years of nuclear experience at home and abroad. GBN‑E will unlock billions of pounds of private and public investment from design to operation, helping to get sites ready for development, and working to grow manufacturing capacity and skills capability.

Our activities will be driven by our values, which are:

Trust - We prioritise safety, we act responsibly and with integrity.

Collaboration - We work as a team; we value diversity and expertise.

Challenge - We are curious and courageous in the way we think and act.

Care - We are thoughtful, inclusive and respectful of others.

Drive - We get things done and we make a difference.
