nuclear fission
Let an agent explain nuclear fission as physics, describe its use in reactors and its history with attribution, address safety and waste questions, and decline weapons or reactor design detail.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain nuclear fission as physics, describe its use in reactors and its history with attribution, address safety and waste questions, and decline weapons or reactor design detail.
A nuclear reaction in which a heavy atomic nucleus splits into lighter nuclei, releasing energy, neutrons and radiation, occurring spontaneously in some isotopes and induced by neutron absorption or photons in others, with variants such as fast, ternary and photofission; fission powers nuclear reactors and is described here as physics, energy and history, without design or weapons detail.
What it is for: Splitting heavy nuclei to release energy.
It can be explain the physics of fission; describe reactor use in general terms; address safety, waste and history; refuse weapons or design detail.
