Burnable absorbers are key components in modern nuclear reactor design, serving to mitigate the excess reactivity inherent in fresh reactor cores while simultaneously enhancing operational safety and ...

Commercial nuclear reactors all work pretty much the same way. Atoms of a radioactive material split, emitting neutrons.

Fireplaces are cozy until it’s time to shovel out the ashes. Nuclear power has the same problem: abundant, reliable energy ...

The OTA provides a framework for the DOE to review and authorize the design and operation of the TETRA reactor. This system ...

At the intersection of mathematics and nature, scientists have found intriguing and often beautiful designs. Pinecone scales ...

Reactor radiation-shielding optimization methods are proposed by combining many-objective evolutionary algorithms with particle-transport calculation software that can optimize the reactor ...

All the different types of small modular reactors generate heat the same way: by splitting heavy atoms and capturing the heat into a variety of materials — like water, liquid metal or molten salt — ...

Preliminary testing has taken place of an ultrasound system which is designed to provide an additional picture of the BN-800 fast neutron reactor core at Beloyarsk Nuclear Power Plant. Beloyarsk unit ...

ARC Clean Technology has raised Series B funding to accelerate commercialisation of its 100 MWe sodium‑cooled fast reactor, ...

NuScale Power ( SMR +14.36%) is a nuclear company with first-mover advantage: It's the only reactor developer in the U.S.

Theoretically, there's no better, more practical source of reliable, carbon-free energy than the current generation of nuclear reactors. In practice, the theory holds water, but there are still a few ...

The Year Ahead: Key Events at the IAEA in 2026 From strengthening safeguards and helping countries build resilient nuclear fuel supply chains to enhancing radiation protection for patients, 2026 will ...
