What's the name / term for trapped pockets of heat in nuclear reactor core? It has a name, but I can't remember it. HELP?

"When a reactor is shut down, the control rods inserted, the core sometimes retains pockets of heat that have to be purged by cycling the core. Heating it then cooling further". The term you are looking for is: Heat up.

The rise in temperature of the reactor fuel rods resulting from an increase in the rate of fission in the core. ...then you add: "Heating it then cooling further". The term for this process is: Heat Exchanger.

Any device that transfers heat from one fluid (liquid or gas) to another fluid or to the environment. ...and the way to get rid of trapped pockets of heat in a nuclear reactor core is thru a: Heat Sink. Anything that absorbs heat.It is usually part of the environment, such as the air, a river, or a lake.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
