How large of an area around the chernobyl reactors will be uninhabitable and for how long?

When would it have been the safest to live around Chernobyl?

No of course not ,chernobyl disaster has cause many innocent loves to be lost it has atoms particles that have exploded leaving radiation ard which is thus unhealthy for humans if exposed in large amts

Is the large nearly uninhabitable island located in the North Atlantic that is controlled by the danes?

Greenland.

Is nuclear energy effective?

Yes, nuclear energy is effective in terms of generating large amounts of electricity with low emissions of greenhouse gases. However, it comes with challenges such as the safe disposal of radioactive waste and the potential for accidents like Chernobyl or Fukushima. Balancing its benefits and risks is an ongoing debate in the energy sector.

Where will the nuclear reactors be constructed?

There are many plans to build new reactors in Canada and the United States especialy, and other countries, such as India and China, also have plans to build new reactors, while many developing countries plan to build their first reactors. Reactors must be constructed near large bodies of water, however, as this is essential to their operation.

What is the capital of chernobyl?

Chernobyl is neither a capital, nor a country. Chernobyl was a city close to the Chernobyl nuclear power station. The power station actually sat close to Prypiat Ukraine, where many of the workers lived. It was close to the Ukrainian and Belarus border. It became famous for having a large nuclear disaster on 26 April 1986. The city is now abandoned and is a ghost city inside the Chernobyl exclusion zone.

How do coolant systems work in nuclear reactors?

Coolant Systems on a Nuclear Reactor works by pumping large amounts of Sea Water into the reactors to cool it down and produce steam.

Do nuclear reactors supply a large amount of energy using a very small amount of fuel?

yes

What type of nuclear reaction is used in modern day nuclear reactors?

Modern day nuclear reactors primarily use fission reactions, where the nucleus of an atom is split into smaller fragments, releasing large amounts of energy. Fission reactions are controlled in reactors to generate heat, which is used to produce electricity.

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.

Could Tokyo end up like the city of Chernobyl if the damaged Fukushima Daiichi reactors were to meltdown?

Although the situation now seems to be relatively under control, there is still a small possibility of a meltdown at the Fukushima Daiichi plant. Anyhow, to answer your question, yes - Tokyo could end up like Chernobyl in the event of a meltdown. An area of about 25 miles around the Chernobyl plant is considered 'The Land of the Damned' - uninhabitable by humans due to the prevalence of Cesium-137 particles that attach to the skin and explode, causing cell mutations. But Tokyo is more than 150 miles from Fukushima - could the radiation reach this far? Definitely. The fallout from the Chernobyl blast drifted thousands of miles into most of Europe, but much of it (almost 60%) settled in the nearby state of Belarus. If the winds were to blow nuclear fallout over Tokyo, and it settled, a large-scale evacuation would be necessary. Millions would need to be relocated. It would be a disaster. Edit: I strongly disagree. From my reading, Chernobyl was a very particular kind of incident only possible with such a poorly designed reactor. In the event of a full meltdown at Fukushima, the most dangerous radioactive materials will most likely stay contained in the reactor. If the inner containment is breached, radioactive iodine and cesium will be released to the atmosphere, but there is no reason to believe the damage will be as widespread or acute as Chernobyl. More: Now, on June 1, TEPCO, which owns the plant admits that the core of reactor 1 is completely melted down into a lump at the bottom of the reactor vessel, reactors 2 and 3 have both melted down at least partly, and there has been a fire in the spent fuel pool of reactor 4. There has been some damage to containment of at least one reactor, and fuel has leaked. And at present, TEPCO is saying the situation will be stable by some time in April of 2012. Tokyo is rather far from all of this, however. The chance of its having to be evacuated is quite small.

How does water cool down nuclear atoms from exploding?

Water is used in nuclear REACTORS both as the heat energy carrier and as a coolant to prevent overheating. Proper cooling is required or the reactor will overheat, causing a meltdown. This is not the same as a nuclear explosion since all that will happen is the extreme heat will melt or destroy the reactor or its containment, but due to the design of reactors it is impossible to have a nuclear explosion similar to nuclear weaponry in a reactor. A notable reactor meltdown was Chernobyl where the nuclear reaction was allowed to generate too much excess heat and the heat caused melting of reactor components and eventually a steam explosion (water vapour explosion) due to overheating. The main concern for a reactor meltdown is not the immediate destruction of everything in a certain radius but the spraying of highly radioactive materials found only in a reactor over a large radius since this radioactive waste cannot be cleaned effectively and will render the surroundings uninhabitable for decades.

What was bad about the Chernobyl explosion?

The release of a large amount of radiation, the death of about 50 firefighters and plant staff, the evacuation of the neighbouring town and area.
