Which outcome inhibits sustained nuclear fission of Uranium-235?

💡 Explanation

Fission stops when neutrons are insufficient for further reactions because neutron absorption by fission products increases ('neutron poisoning'). Therefore, chain propagation terminates, rather than acceleration from temperature or moderator rate changes at nominal levels.
