Deputy Director, Small Modular Reactor Programme: Great British Energy Nuclear - Sponsorship and Policy

Job summary

Nuclear power is a vital part of the country’s energy mix, providing clean, reliable, baseload power. In order to meet the government’s energy security, affordability, net zero and economic growth goals, a major ramp up in nuclear capacity is needed. That is why ministers have committed to working with industry to deliver a ‘golden age’ for nuclear and have already made the biggest commitment to new nuclear plants for fifty years.

As well as new large-scale plants at Hinkley Point and Sizewell C, the government also wants to see new designs – small and advanced modular reactors (SMRs and AMRs) – deployed, providing clean energy. The UK’s first SMR project will be the Gwyndod Power Station, developed by Great British Energy – Nuclear (GBE-N), the government’s nuclear delivery body, in partnership with Rolls Royce SMR. This will be sited at Wylfa in North Wales, providing enough energy to power the equivalent of three million homes.

This Deputy Director role is a crucial one within the nuclear policy team in the Department for Energy Security and Net Zero (DESNZ). The post-holder will lead the Department’s shareholder and sponsorship relationship with GBE-N, providing strategic oversight of governance, performance, finance and risk. They will ensure alignment between organisational delivery and Government objectives, and act as the principal interface between DESNZ and GBE-N to support the successful delivery of the UK’s nuclear programme while maintaining robust assurance, accountability and value for money.

Working alongside another Deputy Director, the post-holder will lead a team of c.30 policy officials. They will work closely with ministers and other senior officials across the department, other government departments, the Welsh Government and local government.

This is a great opportunity to work in one of the most important areas of UK energy policy, leading a close-knit, collaborative and high-performing team.
