1. 01
   Nuclear binding-energy difference —drives→ Nuclear fissionestablishedclaim record

   nuclear → kinetic · loss to radiative

   • for neutron-induced fission: a fissionable nuclide and an incident neutron in an energy range with non-zero fission cross-section
   • critical geometry is required only for a self-sustaining chain reaction; a moderator is reactor-design dependent

   About 200 MeV per event, almost all as fragment kinetic energy (Frisch 1939); thermalisation is a separate step.

   Nuclear fission —produces→ Hot gasestablishedclaim record

   kinetic → thermal · loss to radiative

   • fission heating produces a vapour or gas working fluid in a DIRECTLY heated, same-circuit configuration: the reactor coolant itself boils in the vessel and its steam goes to the turbine (a boiling-water reactor), or the fissioning or fission-heated gas is the working medium (a gas-core or fissioning-plasma reactor)
   • not a pressurised-water reactor: there fission heats a pressurised liquid whose heat crosses a steam generator into a separate secondary circuit — the heat exchanger, not the core, makes the turbine's steam, and that topology belongs to the system layer, never hidden inside this claim (pass 38)
