Introduction:

Hello, today we are going to present you, a presentation about nuclear power. We are going to exlapin:

How it works? Where you can you find “plants” of the saurce and why? If it can be used in Netherlands or in Spain and why or why not? What is the effect on the environment?

We worked in a group of 7 people, and everyone had to answer a question about the nuclear power.

Now we will explain to you how it works: 2nd part:

High pressure prevents water in the reactor vessel from boiling. The super-heated water is carried to a steam generator, which is made up of many small pipes. The water from the reactor is pumped back into the reactor vessel and reheated. The steam from the turbine is a machine in a condenser and the resulting water is sent back to the steam generator. As of March 1, 2011, there were 443 operating nuclear power reactors spread across the planet in 47 different countries.


- Can be used in the Netherlands or in Spain, why? Why not?

-In Netherlands are some nuclear energy, there are 2, because the Dutch chose a policy that required reprocessing all spent nuclear fuel.

-They began studying nuclear energy in the 1930.There are one that is ative plant and other that is closed plant.

Comment of Ms. Doolaard

Try to make the introduction so, that it grabs the audience's attention. So already in the first sentences you're making your point. In your explanation is not how the water is heated up. In the Netherlands is only one working nuclear power plant!

- Can be used in the Netherlands , why? Why not?

They can be used in the netherlands. And There aré 2.

 1 is  a working factory in the netherlands. And 1 is a closed factory. They aré located, the active plant in Bossele And the closed plant is in Dodewaard.

Comment of Ms. Doolaard

It is not clear if it is used in Spain. In the Netherlands is only one active plant, the other one was closed.

Introduction:

Hello, today we are going to present you a presentation about nuclear power. We are going to explain how nuclear power works, Where we can find 'plants' of the source and why, If it can be used in the Netherlands or in Spain, and why or why not, What is the effect on the environment.

We worked in a group of 7 people, and everyone had to answer a question about nuclear power.

How does nuclear power works? 1st part

We make nuclear power in almost the same way, as how you make other energies. The creator makes heat from the energy, and the water turns into steam. Then there is going to be a process, called nuclear fission. First water turns into steam, I already told. Then the steam turns into a turbine called a generator. And then this generator produces electricity.

Comment of Ms. Doolaard

Your explanation is not totally correct. The proces starts with nuclear a nuclear reaction producing a lot of heat. This heat is used to heat up water, that is converted into steam, etc.

-what is the effect on the environment?

nuclear power has at least four disadvatages on the environment:

-they need to spent fuel to let the power plant work.

-they need to get waste rocks at mines to make a fire in the plants.

-the plant releases a small amount of radioactive stuff during a operation.

-during accident it could realease a large amount of dangerous radioactive materials.

  • people studied and have been done on possible effect of nuclear power in causing cancer.
  • a nuclear power plant gets out a lot of carbon dioxide and it´s bad for the nature and human health.
  • a nuclear power plant is quite dangerous. while the technical plants are really good there is a chance that there happens a accident, it is dangerous for the people who live surround.
  • What is the effect on the animals?

-The most common effect on the animals is in their size. Radioactive dosis make them at least 2 times bigger!

-Also the mutations are very common on the animals because radioactivity affects on their cells.

Commentaar of Ms. Doolaard

What are the consequences of radioactivity on humans, animale and plants. What does this mean for harvng radioactive waste and accidents in nuclear power plants? The first three pictures are irrelevant. The fourth picture explains how it works, nothing about the effect on the environment.

Nuclear power factories can be used in Spain and in the Netherlands. These factories can be used and build here because;


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 the trucks which bring large components during the construction.
  - Is there enough cooling water? Which is 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 or country is suitable for a nuclear power plant :

In the 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. 

In 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 

Nuclear power factories can be used in spain because in spain there is enough cooling water, which they can transport to the factory.

There aré 7 Nuclear power factories in spain. They aré located in;. (Point on in the picture on the PowerPoint.)

We first answered the questions with help of the internet. Then we discussed who schould do what and discussed the answers in couples. In the main time a couple made the powerpoint. It went very well because we helped each other and had a good teamwork.

Comment of Ms. Doolaard

In my opinion, nuclear power does cause pollution, but it is different from fossil power. You describe if it can be build in Spain and in the Netherlands, but are they build? Your conclusion is not about what you´ve written down.

where can we find nuclear power plants and why?

There are nuclear power plants all over the world. The most are in the USA, Japan and France. In Africa, there are very less nuclear power plants. This is because Africa isn't an industrial continent, but Asia and North America are. Nuclear power plants are there because they use the heat from a big nucleus like uranium to put water into steam. Because of this steam, generators can produce energy.


How does nuclear power work?

We make nuclear power in almost the same way, as how you make other energies. The creator makes heat from the energy, and the water turns into steam. Then there is going to be a process, called nuclear fission. First water turns into steam, I already told. Then the steam turns into a turbine called a generator. And then this generator produces electricity.

These are my 2 questions I needed to answer.

Comment of Ms. Doolaard

Use a picture to explain how it works. In the answer to your first question you should remove the last two sentences.

How does the nuclear power works

-A nuclear reactor produces and controls the relase of energy from splitting the atoms of uranium, and burning coal. That produces steam, that steam goes to a turbine and from that turbine it goes to a generator an that generator make that electricity and it goes to the city.

-Risks of nuclear power:

-Radiation:

-The principal risks associated with nuclear power arise from health effects of radiation.

-Radioactive Waste:

-The radioactive waste products from the nuclear industry must be isolated from contact with people for very long time periods.

-Other Radiation Problems:

The effects of routine releases of radioactivity from nuclear plants depend somewhat on how the spent fuel is handled. A typical estimate is that they may reduce our life expectancy by 15 minutes.

Comment of Ms. Doolaard

Your picture is irrelevant. Use a picture that is really helping you to explain how it works. In a Nuclear power plant, only uranium atoms are split. Coal is not burned. You didn´t use your own words.
