Thermal runaway - Wikipedia
WEBThermal runaway describes a process that is accelerated by increased temperature, in turn releasing energy that further increases temperature. Thermal runaway occurs in situations where an increase in temperature changes the conditions in a way that causes a further increase in temperature, often leading to a destructive result.

WEBMay 5, 2021 · Thirty-five years after the Chernobyl Nuclear Power Plant in Ukraine exploded in the world's worst nuclear accident, fission reactions are smoldering again in uranium fuel masses buried deep inside a mangled reactor hall. "It's like the embers in a barbecue pit," says Neil Hyatt, a nuclear materials chemist at the University of Sheffield.

Nuclear meltdown - Wikipedia
WEBNuclear power plants generate electricity by heating fluid via a nuclear reaction to run a generator. If the heat from that reaction is not removed adequately, the fuel assemblies in a reactor core can melt.

WEBMay 12, 2021 · Over the past five years, a sensor keeping count of neutron emissions deep within the rubble of the Chernobyl nuclear power plant has kept track of a gradual spike in activity. The rising count might be nothing. It might even drop back down again, given time.
What do we know already about reactor runaway? – A review
WEBMar 1, 2021 · Reactor runaway criteria can be applied to define the boundaries of safe and unsafe regimes through distinguishing the runaway and non-runaway states. This feature allows to apply criteria in off-line tasks (like process design, optimization) and in on-line tasks too (like early warning).
Nuclear reactions at Chernobyl are spiking in an inaccessible chamber
WEBMay 11, 2021 · Scientists monitoring the ruins of the Chernobyl nuclear power plant in Ukraine have seen a surge in fission reactions in an inaccessible chamber within the complex.
Nuclear chain reaction - Wikipedia
WEBIn nuclear physics, a nuclear chain reaction occurs when one single nuclear reaction causes an average of one or more subsequent nuclear reactions, thus leading to the possibility of a self-propagating series or "positive feedback loop" of these reactions.
