Canada could elect to build its own enrichment capacity but according to one expert it would cost at least $100-billion and ...

Only one (or possibly two) of the missing bombs was fully assembled at the time it was lost. The total number of confirmed ...

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 ...

which induced and controlled a nuclear chain reaction, causing uranium atoms to continually split. These, and the earlier efforts of Rutherford, laid the groundwork for the creation of atomic ...

The Nuclear Safety And Security Commission noted on the 24th that it would allow the restart of the Saewool Unit 1 nuclear ...

By the end of the year the physicist Werner Heisenberg had calculated that nuclear fission chain reactions might be possible. When slowed down and controlled in a "uranium machine" (nuclear ...

This elevated concentration was crucial as it allowed for a sustained nuclear chain reaction, something that is meticulously replicated in the fuel enrichment process of contemporary nuclear reactors.

Critical mass is a physics term describing the point at which there is sufficient density to attain a sustained nuclear chain reaction. It gets adapted to describing any situation where sufficient ...
