Since the first nuclear explosion in history during the Trinity test in 1945, nuclear weapons have significantly shaped the ...

Scientists have been building nuclear weapons for more than 80 years, but crafting this technology remains a challenge.

Different isotopes of a single chemical element are distinguished ... SRS produced the Pu-239 from a combination of uranium-235 (U-235) and U-238 in the reactors. U-235 in this “fuel” released ...

Natural isotopes of uranium are U-238, U235, and U-234 (see table above for natural abundances). Depleted uranium contains less of the isotopes U-235 and U-234. The specific activity of depleted ...

In its natural state, it consists of three isotopes (U-234, U-235 and U-238). Other isotopes that cannot be found in natural uranium are U-232, U-233, U-236 and U-237. The table below shows the ...

This isotope of hydrogen is called deuterium ... heavy water can employ a form of uranium commonly found in nature (U-238) rather than requiring so-called enriched uranium, which contains a ...
