The historic move is a step on the long path ahead for nuclear power:

The U.S. has just given the green light to its first-ever small modular nuclear design, a promising step forward for a power source that remains controversial among some climate advocates but is experiencing a popular renaissance.

The Nuclear Regulatory Commission approved the design, which was published Thursday in the Federal Register, from NuScale, an Oregon-based reactor company. The publication of the design in the Register allows utilities to select this type of reactor when applying for a license to build a new nuclear facility. The design would be able to produce a reactor about one-third the size of a usual reactor, with each module able to produce around 50 megawatts of power.

[...] Just because a design is on the books doesn't mean that it's smooth sailing for the industry or that all our grids are going to be powered by carbon-free nuclear electricity in a few years. NuScale is currently working on a six-module demonstration plant in Idaho that will be fully operational by 2030; the company said this month that its estimates for the price per megawatt hour of the demo plant had jumped by more than 50% since its last estimates, in an uncomfortable echo of ballooning costs associated with other traditional nuclear projects. Small modular reactors still produce nuclear waste, which some environmentalists say is a concern that can't be overlooked as the industry develops.
