Researchers Develop Groundbreaking Sensors for Nuclear Reactors

UPDATE: Researchers at the University of Maine have announced a breakthrough in nuclear technology, developing microelectronic sensors that can withstand the extreme heat and radiation levels of a nuclear reactor’s core. This urgent advancement promises to revolutionize real-time monitoring of nuclear reactors, providing essential data for engineers and operators.

The new sensors were successfully tested at the Nuclear Reactor Laboratory at Ohio State University, where they endured temperatures reaching 1,500 degrees Fahrenheit (800 degrees Celsius) for five days. “The successful development of these sensors will address and alleviate technology barriers that currently hinder the rollout of advanced nuclear reactors,” stated Mauricio Pereira da Cunha, the project’s principal investigator.

These tiny sensors, measuring just 100 nanometers thick, are designed for advanced high-temperature reactors that utilize helium gas and ceramic materials. These reactors operate at higher temperatures, enhancing thermal efficiency but making it challenging for existing sensors to survive. The researchers dedicated two years to perfecting these sensors, leveraging two decades of experience in sensor technology.

All seven tested sensors showed remarkable resilience, remaining functional without degradation after exposure to intense operational conditions. “In addition to extreme temperatures, we’re now also exposing these sensors to intense, in-core levels of nuclear radiation at the same time,” said Luke Doucette, senior research scientist. This dual challenge emphasizes the significant advancements in sensor materials necessary for future nuclear technology.

This breakthrough holds profound implications for nuclear energy, potentially accelerating the deployment of advanced reactors that promise safer and more efficient energy generation. As the demand for clean energy sources intensifies, such innovations are crucial in addressing global energy challenges.

The research was reported by the Department of Energy’s Office of Nuclear Energy, highlighting the urgency of transitioning to more sustainable energy solutions. With these new sensors, the nuclear industry is poised for a transformative leap, marking a significant step towards a more efficient and safer energy future.
