The Energy Department says a small nuclear reactor under development at a national lab has reached a crucial milestone that could allow it to produce electricity in the next few years.

The Pentagon and the Energy Department have airlifted a small nuclear reactor from California to Utah, demonstrating what they say is the potential for the U.S. to quickly deploy nuclear power for military and civilian use.

President Donald Trump has signed executive orders to speed up the development of nuclear power and grant the energy secretary authority to approve advanced reactor designs and projects.
