Danish Salt Reactor Tested at ISIS
Copenhagen-based Seaborg Technologies, member of LINX, is developing a floating nuclear power reactor using molten salt to create a coolant. The moderator is sodium hydroxide (NaOH) and it has recently been tested at ISIS Neutron and Muon Source near Oxford, England, according to Danish trade publication Ingeniøren. The results are to be analyzed by researchers at ESS, European Spallation Source in Lund, Sweden.
Seaborg Technologies’ goal is to complete the world’s first floating nuclear power plant in order to produce electricity in South East Asia by 2025. Another goal is to ensure that the price is low enough to compete with traditional nuclear power plants, which use fossil fuels.
An integral piece of Seaborg’s reactor design is using sodium hydroxide (NaOH) as the moderator. Sodium hydroxide slows the neutrons, allowing them to create nuclear reactions and thereby release energy. The analysis by ESS will allow for further optimization of the reactor design, making the analysis important for security clearance.
Another important factor is ensuring that the moderator is able function in a reactor for 12 years without being replaced or adding more fuel. That is three times longer than what was possible with old molten salt reactors, which used graphite as a moderator. Optimizing the moderator’s operating time is an important financial factor, according to Ingeniøren.
