decay heat

The decay heat production rate will continue to slowly decrease over time.

Recently active fuel rods produce more decay heat than older ones.

But the 'decay heat' from the reaction was still enough to cause the uranium fuel to begin to melt.

These pumps circulate water through the reactor to remove decay heat.

The removal of the decay heat is a significant reactor safety concern, especially shortly after shutdown.

The decay heat in the reactor core decreases over several days before reaching cold shutdown levels.

An inactive nuclear reactor continues to generate a significant amount of residual decay heat.

The cooling is needed to remove decay heat even when a plant has been shut down, due to the long term atomic reactions.

Cooling is needed to remove decay heat after a reactor has been shut down, and to maintain spent fuel pools.

It is this decay heat that sets the requirements for cooling of a reactor after shutdown.

A core damage incident can occur even after a reactor is shut down because the fuel continues to produce decay heat.

Pu-238 makes up only a percent or two, but may be responsible for much of the short-term decay heat because of its short half-life.

The spent fuel is cooled in special pools where the residual decay heat is removed.

This decay of unstable isotopes, and the decay heat that results, cannot be stopped.

The power produced by decay heat decreases as the fission products decay.

This was no solution, however, since the residual decay heat was sufficient to melt everything in the compartment.

Even if the reactor had automatically shut down, there would still remain what is described as 'decay heat' from the accumulated radioactivity.

Decay heat is the heat released as a result of radioactive decay.

Naturally occurring decay heat is a significant source of the heat in the interior of the Earth.

Failure to remove decay heat may cause the reactor core temperature to rise to dangerous levels and has caused nuclear accidents.

This decay heat is the major risk factor in LWR safety record.

To remove decay heat, the water cooling system was kept operating, leaking contaminated coolant to the floor.

It has ample capacity to replace the cooling water boiled off by residual decay heat, and can even keep up with small leaks.

Decay heat is what melted the core of the Three Mile Island reactor.

The decay heat is usually listed as watt/kilogram, or milliwatt/gram.
