Small, transportable and mass-produced “microreactors” are seen as part of the future of nuclear power. And it's underway in ...

A DOGE-driven mass firing of critical nuclear workers sparks alarm and leaves scars, as cost-cutting missteps throughout ...

December — Dr. Enrico Fermi achieves the first controlled nuclear chain reaction, with a natural uranium device moderated with graphite. Fermi conducted the process using the first demonstration ...

Learn more here. In 1942, the Manhattan Project needed to create a chain reaction—a crucial step toward proving that it would be possible to make an atomic bomb. The scientists achieved this sustained ...

The "nuclear" part is the chunk of uranium or plutonium that undergoes a nuclear chain reaction when the bomb is detonated. It's this chain reaction that makes nuclear weapons so devastatingly ...

Their work to achieve the first nuclear reaction in 1942 marked the start of the Atomic Age, and it would change everything—from energy to medicine to the geopolitical landscape. In the 1930s, ...

Critical mass is a physics term describing the point at which there is sufficient density to attain a sustained nuclear chain ...

Canada plans to advance its nuclear technologies by focusing on its signature CANDU reactors and developing small modular ...

Reports suggest the justices are favoring Texas, though a ruling in the state’s favor could counter its recent efforts at ...

As the nuclear reactor “burns” U-235, the concentration of U-235 decreases while radioactive by-products such as fissile plutonium increase. Eventually, the nuclear chain reaction can no longer be ...

Researchers at Los Alamos National Laboratory (LANL) have achieved a significant milestone in the advancement of nuclear reactor technology. For the first time in over two decades, a criticality ...
