University of Liverpool and Copenhagen Atomics Researches Salt Purity for Molten Salt Reactor Commercialization
Researchers from the University of Liverpool and Copenhagen Atomics highlight the importance of salt purity in preventing corrosion in molten salt reactors (MSRs). Their study indicates that high salt purity allows 316L stainless steel to resist corrosion significantly better than untreated salts. Additionally, irradiation testing for MSR materials has started at the High Flux Reactor in the Netherlands, part of the NRG-Pallas program, to analyze material interactions in future MSRs.

A study by the University of Liverpool and Copenhagen Atomics shows that high salt purity is crucial to preventing corrosion of 316L stainless steel in molten salt reactors (MSRs). Untreated salts caused severe corrosion within 1,000 hours, while purified salts showed negligible corrosion after 3,000 hours.
Concurrently, irradiation testing of materials for MSRs has begun at the High Flux Reactor in the Netherlands, focusing on the interaction between molten salts and construction materials. The NRG-Pallas program aims to qualify molten salt fuel and construction materials for high-temperature neutron fields, ensuring ongoing research in this area.
