Engineers Test Small Modular Reactor Fuel Rods

Researchers are conducting tests on small metal rods to improve Small Modular Reactor (SMR) safety. The test setup uses a 30 cm container filled with water and five metal rods thinner than a finger. Engineer Konrad Röschger is testing new materials and concepts for Small Modular Reactors (SMR) at a research facility. The testing process involves electrically heating a bundle of approximately 20 fuel rods simultaneously. The experiment aims to simulate temperatures exceeding 2,000 degrees Celsius, which can occur if water cooling fails in a reactor. This research focuses on developing new capabilities and materials for the next generation of small-scale reactors. Water cooling can reach 2,000 degrees Celsius, while superheated steam can reach 800 degrees Celsius. Hydrogen formation carries an explosion risk similar to the Fukushima reactor catastrophe. Researchers are conducting laboratory tests on fuel rods for small modular reactors (SMRs) to evaluate safety profiles. The testing aims to determine if these smaller reactors offer superior safety compared to the large-scale reactors currently in operation globally. These assessments are being performed well in advance of potential mass production of SMR technology. The research seeks to mitigate risks of explosions similar to those seen at Fukushima and Chernobyl.
