fissioned

Once an atom is fissioned, it is split into smaller atoms and can no longer be fissioned.

In theory, since very little of the material is actually fissioned?

Ironically, when very heavy nuclei have fissioned, their final state is more tightly bound than their initial state.

Fissile material is relatively calm unless it's actually fissioned, which usually requires more than just shooting it.

This material can be recycled into a reactor to be fissioned (destroyed forever not simply buried).

Radiometric dating works on the same principle: look at the ratio of pre-substance to fissioned substance.

It would basically be a Hiroshima style dirty bomb with just 1.5% fissible mass actually fissioned.

A lot of the longer lived actinides cannot be fissioned or transmuted effectively by thermal neutrons so they just build up.

Those can also be considered unspent fuel, and fissioned for energy in fast reactors or with neutrons from D-T fusion reactors.

So chatgpt decided to get wolfram alpha to tell it the energy content of U-238 if it were to be completely nuclear fissioned.

Bwaha, 1kg of uranium produces 8.64 x 10^13 joules of energy when fissioned.

These isotopes, when fissioned, produce about half the delayed neutrons of U-235.

And phrased yet again differently: "Once all the stars burn out and all the uranium is fissioned and the coal burned and the universe is just a homogenous 5 degree kelvin soup of [I'm sure some physicist could tell me whatever fundamental particle it'll be that composes this soup] - what then?
