The atomic radii (empirical) of plutonium and uranium are identical - 175 pm.
The atomic radii of uranium and plutonium are identical.
The critical mass of plutonium is lower, plutonium is not so expensive as highly enriched uranium, the technology to obtain plutonium is more simple than the isotopic separa-tion of uranium, etc.
Plutonium generally has a lower atomic mass compared to uranium because it has fewer protons and neutrons in its nucleus. Plutonium isotopes tend to have a smaller number of nucleons overall compared to most uranium isotopes, resulting in a lower atomic mass.
Uranium and plutonium can form alloys.
Plutonium and uranium can form alloys.
Plutonium is more dangerous: the specific activity is greater, the critical mass is smaller, the chemical toxicity is greater.
Yes, it is possible to recycle "burned" uranium and plutonium.
Plutonium is obtained from uranium irradiated in nuclear reactors, consequently the production of plutonium depends on uranium resources.
Uranium is not easily obtained; and the technology of plutonium is extremely difficult.
Yes, plutonium is generally considered to be more powerful than uranium because it is a more efficient fuel for nuclear reactors and can sustain nuclear chain reactions more easily. Additionally, certain isotopes of plutonium are used in nuclear weapons due to their high explosive potential.
Plutonium and enriched uranium are different materials.Enriched uranium is uranium with a concentration of the isotope 235U greater than the natural concentration of 0,7 %.
