When the neutrons in the reactor rise above a critical level, showing that an excursion has started, the uranium fissions at a rate that creates enough heat to melt the solder. Then high-pressure gas will shoot neutron-absorbing poison into the reactor. Even if other controls have failed, this last-ditch nuclear fire extinguisher will keep...
