A machine learning approach leverages nuclear microreactor symmetry to reduce training time when modeling power output ...

The long-theorized neutron-clustering effect in nuclear reactors has been demonstrated, which could improve reactor safety and create more accurate simulations, according to a new study.

As control rods lift from the water in the core, and neutrons go about the business of splitting uranium atoms, life comes to a new nuclear reactor — the first in the country since its sister ...

In particular, the researchers studied the 94Sr(α,n)97Zr reaction, where radioactive strontium-94 absorbs an alpha particle (helium nucleus), emits a neutron, and transforms into zirconium-97.

Figuring out how to create and control the nuclear chain reaction was the foundation for the 448 nuclear reactors producing energy worldwide today. At present, 30 countries include nuclear ...

The most famous disaster in the history of nuclear power was the result of many small problems—but perhaps the most important problem was the unrecognized presence of a “neutron poison.”. On ...

Global interest in fast reactors has been growing since their inception in 1960 because they can provide efficient, safe and sustainable energy. Their closed fuel cycle can support long-term nuclear ...

The control rods absorb neutrons before they can reach the uranium. Because the fuel rods will give off heat even when the reactor is in shut-down mode, this whole apparatus is kept under water.

Los Alamos, N.M., July 12, 2021--For the first time, the long-theorized neutron-clustering effect in nuclear reactors has been demonstrated, which could improve reactor safety and create more ...
