The small modular reactor (SMR) is a class of small nuclear fission reactor, designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations. The term SMR refers to the size, capacity and modular construction. Reactor type and the nuclear processes may vary.

2023年1月20日 · The U.S. Nuclear Regulatory Commission (NRC) issued its final rule in the Federal Register to certify NuScale Power’s small modular reactor. The company’s power module becomes the first SMR design certified by the NRC and just the seventh reactor design cleared for use in the United States.

2023年1月9日 · Small modular reactors (SMRs) are disrupting conventional notions surrounding nuclear power. Smaller, more compact, and producing minimal emissions, this innovative alternative to traditional nuclear power is receiving more public and private sector attention as governments scramble to meet global energy needs reliably and responsibly.

2023年9月13日 · Small modular reactors (SMRs) are advanced nuclear reactors that have a power capacity of up to 300 MW(e) per unit, which is about one-third of the generating capacity of traditional nuclear power reactors.

2023年5月5日 · Westinghouse unveils AP300, a small modular reactor for mid-sized nuclear technology. US tech company, Westinghouse, has announced the launch of the AP300, a smaller version of its flagship...

Advanced Small Modular Reactors (SMRs) are a key part of the Department’s goal to develop safe, clean, and affordable nuclear power options. The advanced SMRs currently under development in the United States represent a variety of sizes, technology options, capabilities, and deployment scenarios.

2025年1月17日 · Designed with a variety of capabilities, sizes, and deployment scenarios in mind, small modular reactors (SMRs) can be used for power generation, process heat, desalination, and more. SMRs offer the potential for greater modularity, more factory-style construction, and the ability to be matched with loads and scaled to meet demand.

2025年1月29日 · A small modular reactor (SMR) is a nuclear fission reactor that features factory-built-and-assembled modules in a variety of configurations and electricity outputs. About 1/10 to 1/4 the size of a traditional nuclear energy plant, SMRs feature compact, simplified designs with advanced safety features.

2024年8月9日 · The NRC refers to light water reactor (LWR) designs generating 300 MWe or less as small modular reactors (SMRs). The NRC has engaged in varying degrees of pre-application activities with several SMR designers over the past several years.

2020年9月9日 · NuScale’s SMR, developed with the help of almost $300 million from the U.S. Department of Energy, has a generating capacity of 50 megawatts—substantially smaller than standard nuclear reactors,...
