While the first stage used uranium isotopes as nuclear fuel in pressurised heavy-water reactors to produce plutonium-239 (Pu-239) and energy, the second stage is more concerned with plutonium fission.

but that’s nothing compared to acquiring the signature of plutonium-239. After 50 years of trying, physicists have finally managed to analyse the fissile isotope using nuclear magnetic resonance ...

Seaborg submitted a paper on their discovery to the journal Physical Review in March 1941, but the paper was removed when it was discovered that an isotope of plutonium, Pu-239, may be used to ...

The results of the study have provided unique information about the accumulation, distribution and sources of plutonium isotopes in glaciers. The concentration of 239+240 Pu activity turned out to ...

Researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) have successfully synthesized a new isotope of plutonium, plutonium-227. This discovery is highly ...

Isotopes are varieties of the same element whose nuclei have different numbers of a subatomic particle known as a neutron. Most plutonium on Earth, made in reactors, is plutonium 239. Its nucleus ...

The strangest product catalog on earth belongs to the Isotope Business Office ... and of course uranium-235 and plutonium-239 (responsible for Hiroshima and Nagasaki). In this catalog, plutonium ...

When extracted from its ores, 11-235 is already denatured with a much larger amount of the nonexplosive uranium isotope U-238 ... from the explosive plutonium (Pu-239), or from natural uranium.

Beginning in the late 1950s, the U.S. met this challenge by developing nuclear batteries known as radioisotope thermoelectric generators (RTGs) and producing plutonium ... the Pu-238 isotope contains ...
