The time it takes to cool a nuclear reactor down varies. If a reactor has been running at nearly full power and is shut down, it takes several days to even weeks to cool it down. The size of the reactor and the "aggressiveness" of a cooling system will affect the cooldown time as well as the power levels at which the reactor was operating at before shutdown.
If a reactor has been operating for some time at high power and is shut down, fission in the core stops (as it does in any shutdown). But fission products in the core are at a high level because the reactor was operating at high power. These fission products will continue to decay for some time. The decaying fission products will be creating a lot of residual heat for this extended period, too.

How are nuclear reactions that take place in the sun different from the nuclear reactions that take place in a nuclear reactor?
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
What part of the nuclear powerplant does the chain reaction occur?
In the reactor core, which is the volume filled with the fuel assemblies
How long does it take to develope a nuclear power?
it takes about millions and millions of years to develope a nuclear power.
How is the heat generated by the reactor core of a nuclear power plant used to provide power to building?
Within the reactor core of a nuclear power plant all the actions and reactions take place. These reactions release energy in the form of heat. This can be harnessed to provide power to the building.
How do you be safe from nuclear breeder reactor?
Don't go into one, disable the safety mechanisms, and take a bath in the core. A properly operated nuclear reactor, breeder or otherwise, is safer to live next to even in terms of radiation than a comparably-sized coal-fired power plant. Of course, if it's being run improperly (Chernobyl), it's not safe, but the only solution to that is "move."
What is the place where controlled nuclear fission reactions take place?
In the core of a nuclear reactor
What type of reaction take place in a nuclear reactor?
Nuclear fission, not to be confused with fusion.
What is Reactor number four?
The #4 reactor is the reactor at the Chernobyl Nuclear Power Plant (Pripyat, Ukraine) that exploded on April 26, 1986. It is still the worst nuclear accident to ever take place anywhere.
How can we make power on saturn?
The most practical way is to take a nuclear reactor with you when you go there.
How are nuclear reactions that take place in the sun different from the nuclear reactions that take place in a nuclear reactor?
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
Why did the neutrino take so long to discover?
Lack of lab equipment, Cowan Reines proved the existence of the neutrino in 1956 but to do that they needed a nuclear reactor as a source of a neutrino flux
Does the atomic bomb produce more energythan a nuclear reactor?
That would depend on the yield of the bomb, the power rating of the reactor, and the lifetime of the reactor. Bombs release all their energy in microseconds, reactors take years or decades.
Why doesn't nuclear fusion take place in a white dwarf?
White dwarfs are too cool for nuclear fusion to take place.
What part of the nuclear powerplant does the chain reaction occur?
In the reactor core, which is the volume filled with the fuel assemblies
What kind of energy does the sun take in?
The sun can be described as a nuclear fusion reactor - converting hydrogen into helium under intense heat and pressure.
What supplies did it take to invent nuclear fission?
The first reactor in 1942 was a simple pile of graphite with channels for the fuel elements, which were natural metallic uranium
Is radiation still leaking from the nuclear power plant in Fukushima Japan?
US scientists determined this tear that the reactor is still leaking small amounts of radioactive materials into the ocean. The cleanup for this disaster could take as long as 40 years.
