A DRACO ground test would need to capture plume exhaust fully to ensure no radioactive materials are released to the ...

Now, a nuclear startup wants to bury a small reactor underground, using depth as a substitute for the tons of concrete required to safeguard aboveground reactors. The company, Deep Fission ...

The environment is the biggest concern most people have about nuclear power. It is possible for a reactor to melt down, leading to a runaway fission reaction that can spread radiation widely. This ...

All U.S. nuclear reactors, which currently provide more than half of the nation's carbon-free power, are first- or ...

Nuclear graphite plays a crucial role in the operation of high-temperature gas-cooled reactors (HTGRs), serving as a moderator that slows down neutrons to sustain nuclear fission reactions.
