Westinghouse: eVinci Microreactor Gains Approval from US Regulators

The approval by the US Nuclear Regulatory Commission (NRC) of the ALS v2 (Advanced Logic System Version 2) control and instrumentation system for the eVinci microreactor marks a major technological milestone for Westinghouse Electric Company. This final evaluation report ensures safe operation and sets the stage for full automation of this technology.

A breakthrough in energy autonomy

The control and instrumentation (I&C) system, described as the “central nervous system” of a nuclear power plant by the International Atomic Energy Agency (IAEA), enables coordination and monitoring of equipment such as motors, pumps, and valves. The ALS v2 system, developed by Westinghouse, stands out by using hardware components instead of software, thereby reducing human error risks and enhancing operational safety.

Multiple applications and promising scalability

According to Westinghouse, this unique technology minimizes human intervention, even during complex procedures such as load-following. With few moving parts and the ability to supply from a few kilowatts to 5 megawatts of electricity for more than eight years without refueling, the eVinci microreactor operates like a self-sustaining battery. This innovation is designed to be prefabricated in a factory and transported directly in a container to its intended site.

The features of the eVinci microreactor make it an ideal solution for a variety of applications, ranging from powering remote infrastructures to integrating into complex energy systems. Additionally, the recent approval expands the potential use of this technology to existing reactors in the United States, further solidifying Westinghouse’s role as a sector leader.

For Jon Ball, president of eVinci Technologies, this regulatory milestone represents a strategic step in achieving autonomous nuclear operations while meeting the growing demand for sustainable and reliable energy.
