there is one power plant in the netherlands that is still functional, in borselle.

It's called the EPZ.


the second last functional power plant was in Dodewaard, it was made in 1969 and it was closed in 1997 but, it has not been unmantled yet. the government has decided that they will wait for 40 years until they open it again. it was closed because theaa owners had seen that there was a politic climate against nuclear power. and thought, that because of the huge amount of power that it used, it had to be closed

there are also 2 plants that are in holland, but they do not make energy, but they are there for research. these plants are located in Delft (South-Holland) and in Petten (north holland).

in spain, there are 10 power plants, 2 of them are closed, 3 are canceled and 5 of them are active. together they produce 21% of all the energy in spain.

top 3

this is the top 3 of the countries with the most operating nuclear power plants: 1. United States with 104 active plants (producing 30% of the world's energy.) 2. France with 58 active plants 3. Russia with 33 active plants

actually japan should be on the third place becouse they once had 54 active plants but after the Fukushima nuclear disaster, they had shut down all their plants. but now they only have 2 functional plants.

If you want to build a nuclear power plant, you have to look at :

  • Is the area high populated? In case of a radioactive release.
  • Are the people in the area opposed to the plant?
  • Are there earthquakes? Just to be sure that it does not collapse.
  • Are there roads with good condition? For trucks to bring large components during construction.
  • Is there enough cooling water? Used for the turbine condenser.
  • Is there a main grid power line? To get energy for the machines.

Now you can see if an area is suitable for a nuclear power plant :

Netherlands:

  • It is high populated, so you have to search for a place were it isn't high populated.
  • That's to the people around the area.
  • There aren't large earthquakes, so it is possible.
  • The roads are mostly in good condition, so that's also possible.
  • That depends on the area. But if there isn't enough, you can transport it.
  • There are 2 power grids in the Netherlands ; one of 220.000 volt and one of 380.000 volt. So probably you'll have one around that area.
  • Conclusion : Most of the points are possible, so you can build a nuclear power plant in the Netherlands.

Spain:

  • It's not high populated, so it is easy to look for an area which isn't high populated.
  • That's to the people around the area.
  • There are eartquakes, but not many and they're not heavy.
  • The most roads are in good condition, so it's possible.
  • Depends on the area, but if there isn't enough, you can transport it.
  • it has the fifth largest electricity market in Europe, so the area will have grid power lines.
  • Conclusion : Most of the points are possible, so you can build a nuclear power plant in Spain.

What is the effect on the environment?:

Some nuclear power plants remove large quantities of water from a lake or river, which could affect fish and other aquatic life. Huge numbers of animals had to be slaughtered because there were contaminated by radioactive material. A small leak of radioactive materials from a nuclear power plant could have far reaching environmental and human health implications. Radioactive waste is hazardous to most forms of life and the environment. There are many different ways in which the radioactive waste can travel. The air, the ground, ground water, transportation systems and agricultural consumption can all lead to human ingestion or contact with contamination.

WHAT IS IT?

Nuclear Energy is the power produced during a nuclear reaction.

HOW DOES A NUCLEAR REACTOR MAKE ELECTRICITY?

The most important parts of a nuclear reactor are the rods, which absorb neutrons, slowing the chain reaction and the nuclear fuel made of uranium. Immersing and removing the rods, the reaction can be controlled. The reactor starts working when the rods are removed. While the chain reaction, caused with the splitting the uranium with neutrons, forms a great amount of heat. Then the water hates and boils. The steam goes to the turbine and rotate it with great speed, and the turbine sets in motion the generator that makes the electricity. The rest of steam goes to the condenser, it condense in hot water and there are two ways: the water goes to the cooling tower, it cools and goes to reactor, or it goes to the pond and to the reactor goes the filtered cold water.

pro's and con's

pro's Nuclear power costs about the same as coal, so it's not expensive to make.

Does not produce smoke or carbon dioxide, so it does not contribute to the greenhouse effect.

Produces huge amounts of energy from small amounts of fuel.

Produces small amounts of waste.

Nuclear power is reliable.

con's Although not much waste is produced, it is very, very dangerous. It must be sealed up and buried for many thousands of years to allow the radioactivity to die away. For all that time it must be kept safe from earthquakes, flooding, terrorists and everything else. This is difficult.

Nuclear power is reliable, but a lot of money has to be spent on safety - if it does go wrong, a nuclear accident can be a major disaster. People are increasingly concerned about this - in the 1990's nuclear power was the fastest-growing source of power in much of the world. In 2005 it was the second slowest-growing.

Nuclear energy from Uranium is not renewable. Once we've dug up all the Earth's uranium and used it, there isn't any more.

Conclusion

The Nuclear Power is a very good way to produce energy because in comparison with the Fossil Power doesn't make any pollution and also it produces a great amount of energy using a small amount of fuel. But it is more dangerous dangerous source and when it explodes, it kills a lot of people and infects with radiation the affecting territory.
