Moltex Energy
Moltex Energy is developing a next generation nuclear reactor that can produce clean electricity at a lower cost than fossil fuels. The technology is based on molten salt fuel in conventional fuel assemblies. Existing stockpiles of spent nuclear fuel can be used as the fuel source and the electricity produced is entirely flexible. Nuclear can now be considered as a peaking plant, not only baseload. Partnered with New Brunswick Power to deploy the first facilities at Point Lepreau site, Moltex has operations in Canada, the UK, and the USA.

Nttau Digital Ltd
nTtau Digital is developing the digital design tools to reduce the design time of fusion power plants from years to minutes. We have established automated simulation workflows that work with parametric CAD and automatic meshing tools. These are operated within a costing framework developed by Woodruff Scientific with support from ARPA-E that allow fusion power plants to be designed and costed at the same time. The automated simulation workflows generate training data sets for neural networks which then allow us to perform multi-objective optimization. It's pretty slick - the digital assets of the optimized system can be viewed on a flat screen or in VR (using @SciVista's SummitVR(TM)).

New Nuclear Watch Institute Nnwi
NNWI is an industry supported think-tank, focused on the international development of nuclear energy as a means for governments to safeguard their long term sustainable energy needs. We strongly believe that nuclear is vital to achieving binding Paris Climate Agreement objectives and tackling the challenge of climate change. Since our inception, we have been recognised in the press as a high profile nuclear industry body working across the UK and European nuclear sector. We hope this think-tank, NNWI, will ensure that nuclear enegry remains at the forefront of debate. Assisting policymakers and the general public understand the vital need for nuclear energy in meeting our climate change objectives. History Founded by Tim Yeo at the end of 2014 as an interest group New Nuclear Watch Europe (NNWE), which was established to help ensure nuclear power is recognised as an important and desirable way for European governments to meet the long-term security needs of their countries. Since its inception, NNWE has been an industry leader in advocating for new build plant within the UK, Europe, and further afield. NNWE has evolved into the New Nuclear Watch Institute to promote the debate about all aspects of nuclear policy and, we hope, strengthen the case for more investment in nuclear.

World Nuclear News
On a daily basis World Nuclear News (WNN) provides free and accurate public information on the subject of nuclear power. The goal of WNN is to use plain English to place comprehensive coverage of nuclear power in context using background information, expert commentary and links to relevant authoritative sources. Because they are researched from original sources and written in-house by experienced journalists, WNN stories may be freely reproduced under certain licence conditions. The WNN service is supported administratively and with technical advice by the World Nuclear Association and is based within its London Secretariat. It draws on the World Nuclear Association's global network of contacts in industry, academia, research institutes and intergovernmental agencies that include key personnel in enterprises, which account for virtually all of the world's uranium mining, nuclear fuel manufacture, equipment production and nuclear power generation. All WNN stories are available on this free-access website, which is updated every working day (observing UK public holidays). Story headlines and summaries are compiled in the WNN Daily email and, on Tuesdays, in the WNN Weekly email. Both of these are available free by joining our mailing list - visit our website to find out more. Readers can discuss stories on WNN's Facebook page, while the headlines of every story are carried on an RSS feed and through WNN's Twitter account,@W_Nuclear_News.

Moltexflex
We are a UK team of scientists and engineers, focused on the dual challenges of climate change – clean energy at affordable cost. We have designed a very simple nuclear reactor: it uses a fission reaction to produce heat at high temperatures. Our approach is to use the natural properties of the materials, tuning the chemistry and physics so that the reaction happens simply and safely. This isn’t complex engineering and sophisticated systems, it’s about simple, natural solutions. The elegant appliance of science means that our device uses standard materials, has no moving parts and is inherently safe. It is easy to construct, install and operate, leading to low costs – lower than coal, oil or gas. The heat: makes electricity; replaces fossil fuels in industries needing high temperatures; and produces hydrogen to replace gas or as the feedstock for new synthetic fuels. These simple devices will contribute to every aspect of decarbonisation and on any scale – from single units to large arrays, from tens to thousands of megawatts. They will power data centres, desalination plants and steel foundries, or whole nations.

Sizewell C Consortium
As a Consortium, we are all different. Our membership includes over 200 businesses, supply chain companies and trade unions from every walk of life, and every part of the country. From scientists, to welders, builders, manufacturers, caterers, coders and more – we all stand ready to deliver one goal: Getting Sizewell C built for Britain. Why we support Britain’s next nuclear power station: Built by Britain: UK-based companies will receive 70% of the project’s construction value: that’s over £14 billion benefiting British businesses and supporting UK jobs and industry. Jobs and skills across the UK: Through a nationwide supply-chain, Sizewell C will bring over jobs to workers and businesses throughout the country, stimulating bottom-up economic growth. Certainty for our ready and raring nuclear supply-chain: Sizewell C will bring national and constituency level jobs and contractors that will pioneer all forms of nuclear technology to secure Britain’s energy future could fall by the wayside. Unleashing our industrial potential: Britain has long been a leader in energy infrastructure, but hope has faded towards our ability to build for ourselves – building Sizewell C can show that all to be wrong.

Fermi Development
As the UK advances toward its 2050 net zero carbon emissions target, the role of nuclear energy has become indispensable. Existing and planned nuclear projects only account for 30% of the required 24 GW of nuclear capacity needed to meet this target; the market for new nuclear developments is therefore 17 GW. Fermi Development offers a unique solution to seize this opportunity by integrating modular nuclear technologies with an advanced development strategy to unlock value and reduce risk at each stage of the project development lifecycle.
