About us
Nuclear Restoration Services (NRS) is responsible for safely decommissioning 14 nuclear sites across the UK.
About us
A world leader in its field, Nuclear Restoration Services (NRS) is responsible for safely decommissioning eleven first and second-generation nuclear sites, the former centre of fast reactor research and development, Dounreay and two research sites across the UK, restoring the sites for all our futures. We also operate a hydro-electric plant.
Hunterston B joined NRS on 1 April 2026 as the first advanced gas-cooled reactor (AGR) site to be decommissioned. Hinkley Point B will follow in autumn 2026. Dungeness B, Torness, Heysham 1 and 2, and Hartlepool will join NRS as they are defueled over the next decade.
Who we are
NRS is a wholly owned subsidiary of the Nuclear Decommissioning Authority (NDA) and is responsible for safely decommissioning 14 nuclear sites and operating one hydro-electric power station.

Each site has a Site Stakeholder Group (SSG) or Local Site Liaison Council (LCLC) which acts as a liaison between the local community and the site. Independently chaired, the groups meet regularly to examine our work, as well as that of the Nuclear Decommissioning Authority and regulators. Membership includes local councillors, non-governmental organisations and other interested stakeholders. Find out more about our SSGs and LCLCs.
Dounreay
Dounreay is a division of NRS. It was the centre of the UK’s research programme into nuclear fast breeder reactors for four decades, and is now a site of decommissioning, major construction and waste management as it dismantles one of the most complex and hazardous legacies of the 20th century.

Responsibilities
We are responsible for the delivery of value for money decommissioning and restoration of Government owned nuclear sites, ensuring all our futures are safe, secure and sustainable.
What we do
We manage our sites through their lifecycles, overseeing all aspects of operation, defueling, decommissioning, care and maintenance, and final site clearance.
This includes sending all used NRS fuel safely to Sellafield for reprocessing.
We deliver our mission through a programme of decommissioning across the UK. This means that some sites will be dismantled, while others are placed in a deferral state for a period of time before final site clearance.
Care and maintenance (C&M) is the name for this deferral state. C&M enables radiation levels to decay naturally over time. The sites are monitored during C&M and planned maintenance and inspections take place. Bradwell was the first UK nuclear site to be placed in C&M in 2019.
Final site clearance is the last lifecycle stage when the reactor vessels are dismantled and remaining waste is sent for disposal.
Our decommissioning programmes will cover 720 hectares and sustain thousands of highly skilled jobs across three nations.
How we do it
We have four parts to our strategy:
-
Deliver our existing commitments safely, securely and sustainably
-
Transform how we operate our business
-
Innovate across technology, systems thinking and the future potential of our sites
-
Grow to take on new missions, in a careful and considered way.
Priorities
Our delivery goals over the next 10 years are to decommission our sites so that:
-
Safety, security and sustainability is at the heart of everything we do
-
Fuel and waste is retrieved, treated and disposed of
-
Buildings are dismantled or demolished
-
Land is de-designated or reused.
