Researchers at North Carolina State University have made a groundbreaking discovery in the field of molten salt analysis. The team has developed a technique called “plasma bubble spectroscopy” that can detect and measure elements in molten salt solutions.
The new method uses a specialized probe that can withstand the extreme conditions of the molten salt environment. The probe creates a plasma bubble within the salt, which emits a unique glow of different light colors. A spectrometer then analyzes this light to identify the specific elements present in the salt.
This breakthrough has significant implications for the development of advanced nuclear reactors using molten salt as a coolant. Molten salt reactors offer several advantages, including the ability to operate at near-atmospheric pressure even at high temperatures and substantial energy storage capacity.
The challenge with molten salt reactors is accurately detecting and understanding the distribution of nuclear fuel and other materials within the coolant. The plasma bubble spectroscopy technique can overcome this hurdle by enabling the measurement of fuel quantities in the salt at any time, aiding in salt processing and material accountancy.
The research team is now focused on refining the technique and exploring its potential applications. They plan to collaborate with national laboratories and industry partners to further develop and commercialize the technology. This breakthrough has the potential to expedite the development of advanced nuclear reactors and contribute to a cleaner and more sustainable energy future.
