The rise of AI has led to an explosion of new data center build-outs, but power consumption has become one of the key bottlenecks to further expansion. That's fueled intense interest in small nuclear reactors that can be built right into newer data centers, such as the new eVinci microreactor from Westinghouse, which is designed to output five megawatts of power and work 24/7 for over eight years without refueling.
Westinghouse Electric Company, one of the leaders in nuclear power plant construction, has submitted its Preliminary Safety Design Report (PSDR) for the eVinci Microreactor to the National Reactor Innovation Center (NRIC) at the U.S. Department of Energy (DOE). This is a crucial step required at the Idaho National Laboratory (INL) so that the eVinci can be deployed for testing at the NRIC’s Demonstration of Microreactor Experiments (DOME) facility. Westinghouse also says that it’s the first company to do so, making it one of the pioneers in microreactor technology.
