Why is it necessary to enclose the nuclear reactor at low temperature?
To keep the environment inside the power plant cool.
Why is the water that is used to cool the reactor vessel of a nuclear power plant is kept separate from the water that is heated to produce steam for the turbine generators?
To reduce radioactive contamination.
Why nuclear power plant explodes?
Nuclear power plants don't explode, in the style of a nuclear bomb. That particular super prompt criticality is impossible to maintain for the length of time necessary to consume the core, leading to a true, nuclear detonation. If you are thinking about the explosions that occurred at the Fukushima Daiichi Nuclear Plant, those were hydrogen gas explosions. Hydrogen gas built up as a consequence of the high temperature of the zircalloy fuel pins in contact with water. When additional water was added to help cool the fuel, the hydrogen combined with the oxygen in the water under temperature and exploded. Again, it was not a nuclear explosion.
How long does it take a nuclear reactor to cool?
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.
Nuclear power plants require large volumes of what to cool reactors and convert heat to electricity?
Nuclear power plants require large volumes of water to cool reactors and convert heat to electricity. Reactors use normal water, heavy water, and even newer reactors use other forms of coolant.
Can you use salt water in coal powered electricity stations?
Yes - some power stations located on the coast use sea water to cool the condensers. Examples of this include:Gladstone Power Station in Queensland, AustraliaKoeberg Nuclear Power Station in South Africa
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! :)
What are some factors that make environmentalists against nuclear power stations In other words what are the major environmental effects of a nuclear power station?
Nuclear power stations use local water supplies to cool their reactors and dump a lot of ambient heat into the environment as a result. Many also have concerns about the radiation in the plant and its effects on the environment should the plant become breached and the fact that the nuclear waste produced by the plant will remain dangerous for thousands of years wherever it ends up being stored. However, it should be noted that a gram of uranium can produce the equivalent energy of tons of coal, so nuclear plants produce reliable power without burning fossil fuels.
Why coolants are used in nuclear power stations and how much coolant is needed?
coolant is used to keep the reactor cool and prevent it from melting down. The amount of cooling that is required really depends on the the amount of heat being put into the coolant.
What are some problems that are happening with the nuclear power stations in Japan?
There is a lot of nuclear waste that is at risk of exploding, so the workers must keep it covered with water to cool it. This prevents explosion. They had a problem with the back up power going out due to the tsunami, and this caused more explosions Tuesday and Wednesday. A huge concern is the massive amounts of radiation coming from the waste.
Why were the nuclear power plants in Japan where they were?
The power plant were where they were because the generators needed cool water for the cooling systems at the plant.
How did the Nuclear reactor get damiged?
If you are talking about the Nuclear Reactors in Japan, they were damaged because when they lost power, the water pumps used to cool them stopped, and all of the nuclear material overheated.
What caused the nuclear power plant in japan to explode?
The pumps that were supposed to keep the nuclear reactors cool failed to work because the earthquake broke them
What adjective could be formed in book?
the amount of water needed to cool down a a nuclear power station
Why are large amounts if water used in nuclear power plants?
to cool the heating rods and generate electricity
Why is it necessary to enclose the nuclear reactor at low temperature?
To keep the environment inside the power plant cool.
Are generation 3 nuclear plants safe?
Most nuclear power plants are quite safe. The only ones that were inherently unsafe ware the Soviet-made power stations similar to Chernobyl, which did not include a reactor containment building. The nuclear powerplant at Fukushima Daichi in Japan was crippled not by a failure of the nuclear reactor, but by the tsunami following the magnitude 9+ earthquake. The plant survived the earthquake, and the plant operators shut down the reactor, but a nuclear reactor generates a LOT of heat, and takes a while to cool off. When the reactor isn't providing power to run the coolant pumps, external power must be supplied to run the pumps to cool the reactor. Fukushima Daichi had backup diesel generators for this purpose, and power from the electrical grid as a backup - but the tsunami knocked out the generators and knocked down the power grid all along the coastline. The new reactor designs are not susceptible to failure when the coolant pumps go offline.
