Nuclear fission, the process by which an atomic nucleus splits into smaller parts, is a fundamental process in nuclear physics. While the fission of heavy elements like uranium and plutonium is ...

To understand what it means to “enrich” uranium, you need to know a little about uranium isotopes and about splitting the atom in a nuclear fission reaction. What is an isotope? All matter is ...

These findings challenge existing models and highlight the need to better understand how nuclear structure affects fission in the sub-lead region, which includes elements with atomic numbers below 82.

What is uranium enrichment, then? To "enrich" uranium means taking the naturally found element and increasing the proportion of uranium-235 while removing uranium-238. There are a few ways to do ...

Only 0.72% of it is uranium-235 with 92 protons and 143 neutrons (the remaining 0.01% are other isotopes). For nuclear power reactors or weapons, we need to change the isotope proportions.
