Small modular nuclear reactors (SMRs) are considered by the U.S. Department of Energy (DOE) to be "a key part of the Department's goal to develop safe, clean, and affordable nuclear power options."
The concept is an intriguing spin-off of conventional nuclear power plants—instead of constructing a large static facility, build a series of much smaller fission reactors at a central facility that can be mass-produced and then transported to a final destination.
