Because, if they aren't, the excess heat will damage the reactor.

What happen to the nuclear power stations in japan?
they are in a nuclear melt down, things are still really bad on that area
What happened to Kat in series 2 of the sparticle mystery?
to shut down nuclear power stations
What type of power stations do not use chemical energy?
Fossil-fuel power stations, hydroelectric power stations and nuclear power stations.
How are nuclear fuels in power stations to generate electricity?
Think of a nuclear power station as a slowed down nuclear bomb. The heat energy released in the fission process is used to turn water into steam to drive electric turbine generators.
How many power stations have had leaks?
¥There was a leak of dangerous gas from Hinkley point B nuclear power station in 2004.¥In 1986 the Chernobyl nuclear power station in the Ukraine suffered a melt down. This led to 56 deaths.
Why have the nuclear power stations in the UK been shut down?
You are misinformed. All the AGR stations are operational, the magnox ones are mostly shutdown because they have reached the end of life as expected.
What are the ways in which power stations can be powered?
Power turbines are driven by steam. Steam can be raised by thermal, nuclear or geothermal processes. Wind and water can also drive a generator. The auxiliaries for a power station (which I think is what this question is asking) are typically powered by step down transformers within the power station. In nuclear power stations there are often standby-critical supplies which are driven by gas turbines or diesel generators.
Can you shut down a nuclear power plant?
Yes, nuclear power plant can be shut down.
Can traditional power stations be switched on and off at will?
No, they can't, they have to be powered up and down over several hours - especially nuclear power stations. This is why hydroelectric power stations are so useful to deal with surges in power demand, they can go from zero to full in seconds - Dinorwig Hydroelectric powerstation is the fastest, taking 12 seconds to go from 0 - 1,320 mw.
How much coolant aka water is needed for a nuclear power station?
It depends on how much it needs to be cooled down, or transferred. The more heat there is the more coolant (water) is needed.
What is water solid condition in nuclear power plant?
The condition known as going solid means that the reactor is shut down and cooled down, and the pressurizer is completely filled with water. The pressurizer is a component of the nuclear power plant that maintains high pressure on the coolant to keep it from flashing into steam. There is a steam bubble (a large volume) in the top of the pressurizer when the plant is online. Once cooled down and depressurized, we can pump more coolant into the plant to completely fill the pressurizer. The plant is then said to go solid when this happens.
Why are power stations which use nuclear to produce electricity built along coasts in most countries?
Because Neuclear Power Plants need water to cool down the reactors and thus the sea is a great place to get cold water from! :)
