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

What is used in nuclear power stations to cool the reacants down?

Water is commonly used to cool the reactor in nuclear power stations. This water absorbs the heat generated by the nuclear reactions and carries it away, preventing the reactor from overheating. The cooled water is then circulated back to the reactor to continue the cooling process.

What type of power stations do not use chemical energy?

Fossil-fuel power stations, hydroelectric power stations and nuclear power stations.


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.


Can you shut down a nuclear power plant?

Yes, nuclear power plant can be shut down.


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.


How would gas and nuclear power stations be used to to meet the demand of electricity during a twenty four hour period?

Gas power stations can quickly ramp up or down to match fluctuations in electricity demand throughout the day due to their flexibility, making them ideal for meeting peak demand periods. On the other hand, nuclear power stations provide a continuous and stable supply of electricity, making them more suitable for providing baseline power throughout the day and night. By combining these two types of power stations, the electricity demand can be effectively met over a 24-hour period.


How are nuclear fuels in power stations to generate electricity?

Nuclear fuels, such as uranium, are used in nuclear power stations to generate electricity through a process called nuclear fission. In this process, the fuel rods are placed in a reactor core where the uranium atoms are split, releasing a large amount of heat. This heat is used to produce steam, which drives turbines connected to generators, resulting in the production of electricity.


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.


What are the advantages of having all power stations connected to the National Grid?

More power on peak times If one goes down, they can rely on the other power stations
