The paper, published Thursday in the journal Scientific Reports, examines the area within a roughly 20-mile radius of the stricken plant and details the concentration of plutonium isotopes ...

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 ...

You can hold plutonium in your hand, but it has the potential to destroy entire cities. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

The energy released by this fission is known as the “primary” explosion and is harnessed to fuse hydrogen isotopes together ... in nuclear warheads. Plutonium-239 is made by irradiating ...

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.

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 ...
