By designating this reactor as a neutron source, and building it at a DOE site, it will be exempt from licensing and oversight by the Nuclear Regulatory Commission. While NRC licensing is far from perfect, it would be far superior to DOE self-regulation.

Our Energy Sources, Nuclear — The National Academies

Oct 25, 2016· However, it is a challenge to replace the constantly running fossil fuel power plants with sources that are intermittent. Ideally, we'd have a source that doesn't emit CO 2 and is consistently reliable; this is known as a baseload energy source. In this context, nuclear energy is the main alternative energy source that works.

As a result, unlike other energy sources, nuclear power plants do not release carbon or pollutants like nitrogen and sulfur oxides into the air. Nuclear reactors are designed to sustain an ongoing chain reaction of fission; they are filled with a specially designed, solid uranium fuel and surrounded by water, which facilitates the process.
