Army Awards $2.2 Billion for Small Nuclear Reactors
The US Army wants to build small nuclear power plants at five military bases.
It plans to spend $2.2 billion on the project.
The first reactor is supposed to start working by September 2028.
The Army says military bases need dependable electricity.
Today, many bases use diesel fuel when the regular power grid fails.
Nuclear reactors could provide power without needing fuel deliveries.
Several companies will develop and operate the reactors.
However, no small modular reactor is operating yet, so the project still faces technical and approval challenges.
The US Army awarded vendors a combined $2.2 billion to build and operate small nuclear reactors at five military bases.
The Army aims to have the first reactor operating by September 2028.
Five companies, including Antares Nuclear, Radiant Industries, Westinghouse and General Atomics, were selected for the work.
The Army says the reactors could reduce reliance on diesel fuel during power-grid disruptions or conflicts.
No small modular reactor is currently in service, and only NuScale’s design has been approved by the US Nuclear Regulatory Commission.
