Mott MacDonald has signed a Memorandum of Understanding with Holtec Britain and Hyundai E&C to further explore the delivery of Holtec’s Small Modular Reactor (SMR) technology in the UK.
The agreement builds on the Clean Energy Partnership signed between the UK and Korean governments late last year. It also follows the appointment of Mott MacDonald as the delivery partner for the Generic Design Assessment (GDA) of Holtec Britain’s Small Modular Reactor SMR-300 in the UK, having secured £30M of grant funding from the UK Government’s Future Nuclear Enabling Fund for this.
SMR-300 is a pressurised water reactor (PWR) technology based on existing US and UK standards using PWR fuel similar to that already used at Sizewell B and other new UK reactors under development, including Hinkley Point C. This will enable economic viability of fuel fabrication and back-end disposal of the fuel, utilising existing supply chains and further supporting UK energy independence.
The MOU was signed at the Korean Embassy in London, during an event hosted by His Excellency Yoon Yeocheol, the Ambassador of the Republic of Korea to the United Kingdom, and attended by the Prime Minister’s Trade Envoy to the Republic of Korea, the Rt Hon Sir John Whittingdale MP.
Cathy Travers, group managing director, Mott MacDonald said: “SMR technology will bring reliable, affordable and low carbon electricity to industry, homes, and businesses, as well as contributing to the UK government’s ambition of generating 24GW of nuclear capacity by 2050. International collaboration from across the nuclear industry is key to its successful deployment, which is why we are bringing decades of collective experience to bear as we explore this path with Holtec Britain and Hyundai E&C.”
Demand for data centres is growing and using nuclear reactors to power them is one way to ensure the increased energy consumption doesn’t affect the UK’s ability to deliver on net zero, while creating wider community benefits.
Civil nuclear power directly employs over 77,000 people in the UK and is worth £6.1bn to the economy, but the worth is so much more than that.
Meet Jim Grundy, our development director in nuclear. His career journey is one of adaptability, opportunity seizing and long-term growth outlook.
Mariam Thomas is a project manager working within the energy sector who returned to the workforce with a clear sense of purpose and a wealth of transferable skills after a five-year career break to raise her children.
We caught up with Harry to discuss how his role as a nuclear process engineer is helping the UK to meet its net zero targets and how he is supporting new graduates to follow in his footsteps.
Meet Julia Barr, a principal commercial manager, based in our Glasgow office, whose career path in our nuclear team is a testament to adaptability, self-belief and the power of supportive teams.
We caught up with senior process safety engineer Steven Melens to talk about his role in the nuclear civil and defence team within our UK and Europe energy business.
The Department for Energy Security and Net Zero (DESNZ) has awarded Mott MacDonald a contract to deliver technical advisory services in support of government oversight of the Sizewell C nuclear power plant on the Suffolk coast.
Mott MacDonald’s Julia Barr and Natasha Khan have been recognised in the Top 50 Women in Engineering 2025.
Rolls-Royce Submarines has announced the joint appointment of Mott MacDonald and AtkinsRéalis as its new fissile design partners – a key milestone in the expansion of its Raynesway site in Derby.
Our design expertise and seamless digital collaboration are ensuring the Sellafield site will continue to benefit from effluent treatment that reduces risk from high-hazard nuclear material.
SMRs are nuclear fission reactors designed to be built at a smaller size, but in larger numbers than the world’s current nuclear fleet. They are cost competitive and considered to be more versatile, scalable, sustainable, financeable and efficient. With wider-ranging applications such as generation of industrial heat and hydrogen production, SMRs are well placed to help governments worldwide in achieving low carbon ambitions.
