Small modular nuclear reactors (SMR) offer alternatives for providing affordable, secure sources of emissions-free generation to the world’s rapidly changing and diverse markets.

The Westinghouse SMR is a 225 megawatt integral pressurized water reactor with all primary components located inside the reactor vessel. Passive safety systems and proven components - realized in the industry-leading AP1000® plant design - are incorporated throughout to achieve the highest levels of safety and to reduce the number of components required. The Westinghouse SMR is fueled by an adaptation of the Westinghouse fuel design. It also leverages the latest U.S. Nuclear Regulatory Commission-licensed safety and security features.
