Saltfoss Energy

Why put a nuclear reactor on a floating platform? 🚢 Traditionally, a nuclear power plant project is planned around a fixed site, and the site characteristics shape the project from the start. Land conditions, civil works, cooling access, grid connection, local supply chains, permitting and construction logistics all become part of the build. Even with a proven reactor design, the total project can become highly specific to one location. Saltfoss uses the floating platform to move most of that work into a centralized manufacturing process. Each floating power plant is designed to carry up to six molten salt reactor units (each 100 MWe / 250 MWt) alongside balance of plant, high-voltage sub-station and operation facilities, manufactured as a turn-key floating power plant. The floating power plant is designed for a 24-year service life before returning for replacement, refurbishment or decommissioning. This means the power plant can be thought of more like a manufactured product than a permanent civil construction project tied forever to one site. Centralized shipyard manufacturing enables: 🔹 Rapid manufacturing. 3 years from order to turn-key delivery 🔹 Supply chain optimization through repeatable procurement and logistics 🔹 Efficient quality assurance with standardized processes 🔹 Fast and firm timelines using proven shipyard manufacturing 🔹 Serial standardized manufacturing reducing costs 🔹 Fixed location and workforce = high learning rate and staff retention 🔹 Movable floating platform streamlining deployment and decommissioning There is still serious work at the deployment location. Licensing, site approval, grid integration, operations and security remain essential. The difference is that the plant itself can be completed under shipyard manufacturing conditions, using repeatable, standardized processes performed by highly experienced teams.

Mass manufacturing of floating nuclear power plants 🏗️ One of Saltfoss’ main objectives is scalability and deployability. Can nuclear become a manufactured product with easy deployment (like a car) instead of being constructed from the ground up on a fixed site? Our solution is a floating nuclear power plant. By placing molten salt reactors on a shipyard-manufactured “Power Barge”, we enable both efficient central manufacturing and easy deployment. Designed to deliver clean baseload energy where it is needed. Each barge is designed for: 🔹 Up to six reactor modules 🔹 100-600 MWe of combined output 🔹 Above 90% capacity factor 🔹 24-year operating lifetime without refueling 🔹 Turn-key manufacturing at Samsung Heavy Industries’ shipyard 🔹 Easy deployment and off-site decommissioning Nuclear projects have traditionally been shaped by local land conditions, civil works, infrastructure, permitting, and construction risk. We address these challenges by moving most of the work into a controlled industrial setting, with quality, repetition, and manufacturing discipline. Denmark and Korea are both important to this model. Denmark is a knowledge country with a strong engineering culture, a strong track record in deploying energy technologies, leading competences in molten salt, and an ability to attract international specialists who want to live and work in Copenhagen. Korea brings the industrial side, world-leading shipbuilding, advanced manufacturing capability, and established nuclear experience. Saltfoss combines the strengths of both.

Today, we had the pleasure of hosting a company visit with the leaders of five Danish political parties: Venstre, Danmarks Liberale Parti, Liberal Alliance, Det Konservative Folkeparti, Dansk Folkeparti og Danmarksdemokraterne. We greatly appreciated their - and other politicians' - visit and the opportunity to share insights into our work and the technologies we are developing. Last week, the five party leaders jointly announced their intention to repeal Denmark’s 1985 ban on nuclear power. While we leave policy decisions to the political sphere, it remains a fact that a technology-neutral framework for energy research and industry is essential for our ability to innovate and grow from Denmark.

Finishing the last FUNaK experiments before the Friday Social (waffles and beer tasting 🧇🍺). The vessel in the photo contains FUNaK, the molten salt eutectic we use in our reactor. It consists of NaF (sodium fluoride), KF (potassium fluoride), and UF₄ (uranium tetrafluoride). By adjusting the voltage and current applied to the electrodes, we can control the redox states of the compounds in FUNaK - enabling electrochemical control of corrosion. Fascinating stuff! After all, there’s a reason “FUN” comes first in FUNaK. 🧪🤓

Earlier this week, our CEO Klaus Nyengaard and Industry Policy Director Emil Drevsfeldt Nielsen from Dansk Metal guested the popular climate focused radio program "Guld og grønne skove" to talk about "The Danish Nuclear Alliance" that launched recently. The program was titled "From taboo to trend" indicating how people in Denmark - and across the world - are realizing the opportunities in nuclear. Links in the comments.

"Our modeling shows that by 2050 nuclear energy represents 10 – 30% of generation in cost-optimal pathways, lowering total system costs by 2 – 31% compared to renewables only trajectories." "Renewables and nuclear are complementary technologies rather than rivals." Insightful study of emerging markets and developing economies by The Rockefeller Foundation, Bayesian Energy and Radiant Energy Group, that aligns with our experience from working in Asia.

The EU Commissioner for Energy and Housing, Dan Jørgensen, visited Saltfoss last week. The Commissioner’s main points: We need nuclear as part of the mix to meet the growing demand for clean energy, and SMRs + AMRs are promising technologies that the EU is already investing in. Benefits include climate goals, competitiveness and energy independence.

The Danish Nuclear Alliance launches today! Today, together with a range of prominent partners (list below and more coming), we are launching the Danish Nuclear Alliance. Based on a broad alliance of organisation, companies and research institutions, the alliance aims to ensure that nuclear energy is given equal and technology-neutral treatment in Danish energy, industrial and research policies. Based on facts, nuclear energy, particularly new nuclear technology, holds great potential, and the alliance wishes to ensure that Denmark benefits from that.

Last week, we organized an event in Bangkok with our Thai partner, Global Power Synergy Public Company Limited (GPSC), called “Thailand’s energy future and the role of Gen IV nuclear”. In front of an audience of key public and private players from the Thai energy sector, our consortium partners Samsung Heavy Industries and Korea Hydro & Nuclear Power (KHNP) alongside GPSC and ourselves delivered talks about future developments in energy and nuclear's potential. The day ended with a panel discussion with Office of Atoms for Peace, Kasikorn Research Center Co., Ltd., Chulalongkorn University, and GPSC which generated a lively debate among the panel and audience. Thanks to the presenters and audience for the overwhelmingly positive interest, and to the Embassy of Denmark in Thailand for excellent hosting. 🇹🇭 🇩🇰 🇰🇷
