Copenhagen Atomics Advances Molten Salt Reactor Reliability Through Extensive Testing
Copenhagen Atomics has achieved over 100,000 hours of pump runtime in molten salt reactors, addressing key reliability and cost challenges. Their innovative testing strategy and in-house pump development may significantly impact the competitiveness of MSRs in nuclear energy markets.

Copenhagen Atomics has reported over 100,000 hours of combined pump runtime in molten salt reactors (MSRs), focusing on reliability and cost reduction. The company emphasizes extensive empirical data collection as crucial for regulatory approval, with pumps operating continuously for two years at temperatures above 600°C.
Significant advancements include a patented salt purification process that allows for the use of standard 316L stainless steel, reducing costs and enhancing recyclability. The company aims for commercial deployment of MSRs around 2030-2031, contingent on regulatory timelines.
Achieving high capacity factors is critical for market competitiveness, particularly in energy-intensive industries. By addressing both material degradation and pump reliability, Copenhagen Atomics may establish a strong position in the evolving nuclear energy sector.
