On Friday, the Nuclear Regulatory Fee (NRC) introduced that it will be issuing a certification to a brand new nuclear reactor design, making it simply the seventh that has been permitted to be used within the US. However in some methods, it is a first: the design, from an organization known as NuScale, is a small modular reactor that may be constructed at a central facility after which moved to the location the place it will likely be operated.

The transfer was anticipated after the design acquired an okay throughout its remaining security analysis in 2020.

Small modular reactors have been promoted as avoiding lots of the issues which have made giant nuclear crops exceedingly costly to construct. They’re sufficiently small that they are often assembled on a manufacturing unit ground after which shipped to the location the place they may function, eliminating lots of the challenges of customized, on-site building. As well as, they’re structured in a solution to permit passive security, the place no operator actions are essential to shut the reactor down if issues happen.
