U.S. prepares for first new nuclear reactor in 50 years with coolant system upgrade

The U.S. government is set to deploy its first new nuclear reactor in 50 years, a microreactor named MARVEL. A contract has been awarded to Carolina Fabricators to build its primary coolant system, a key component for managing heat. MARVEL will be used for research and testing in microreactor technology. It will operate at high temperatures and generate thermal energy, supporting applications like desalination and hydrogen production. Unlike traditional reactors, microreactors can be factory-made and relocated as needed. The primary coolant system is more complex than previous components, requiring advanced engineering. Scientists at Idaho National Laboratory expect to complete it soon, allowing further development of the reactor. MARVEL is projected to be operational by 2027.
