Nuclear weapons haven’t been tested in the United States since 1992. Find out why, and what could happen if the hiatus ends.

The Japanese nuclear disaster at Fukushima is no longer a leading headline, but the danger posed by the meltdowns hasn't entirely abated. Xenon gas, a byproduct of nuclear fission was detected in ...

Nuclear fission reactors act as a key power source for many parts of the world and worldwide power capacity is expected to nearly double by 2050. One issue, however, is the difficulty of discerning ...

An EPRI study by A. G. Tarditi, J. H. Scott focused on the conversion via traveling wave DEC (direct energy conversion), that has the advantage of being able to generate high frequency power (MHz ...

Many advances in technology spring from the mind of a single genius, but others, like nuclear power, are the product of many minds over generations.

Seven years after the end of WWII, the US detonated the world's first hydrogen bomb. H-bombs use a combination of nuclear fission and fusion and are far more powerful than atomic bombs. Edward Teller, ...

Nuclear physics is a forbidding subject, even for trained physicists. To understand current news and discussions about nuclear science and technology, some background knowledge is required, and the ...

The process of nuclear fission was first discovered in 1938; however, it wasn’t fully explained until a year later. Today – less than 100 years after its initial discovery – it is the poster child of ...
