Transcript of NUCLEAR ENERGY
WHAT IS NUCLEAR ENERGY?
Nuclear power is generally used to generate heat and electricity through the use of nuclear fusion ( releasing nuclear energy by joining uranium atoms) and nuclear fission (splitting the uranium atoms). People began converting nuclear energy into a source of heat and later electricity after radioactive elements were discovered (uranium and radium)
As mentioned earlier, Nuclear Energy is produced by splitting uranium atoms (nuclear fission) causing energy to be released and/or joining uranium atoms (nuclear fusion). The released energy is then used to generate heat for making steam which is used to turn turbines and generate electricity.
Factors to be taken into consideration when setting up a nuclear power plant
A Nuclear Power Plant can impact the environment negatively, it destroys habitats and nuclear waste disposal is very dangerous, especially when combined with radioactive waste
Local Infrastructure is also another important factor to be considered while building a nuclear plant. It will help increase the efficiency and quality and most of the time uranium and other materials are imported which means good infrastructure is required.
Budget is very important as a budget plan will have to be created including travel cost and cost of materials used. Land is also a big factor as nuclear power plants tend to take up a lot of space
Security is a KEY FACTOR as nuclear plants are also terrorist targets because they can explode with many poisonous gasses
Nuclear energy is reusable, the resources required are abundant and its carbon free
Global Use Since 1970s
Chernobyl Nuclear Disaster
Chernobyl is located in in northern Ukraine. Chernobyl's nuclear disaster happened on April 26th 1986. The fourth reactor of the nuclear power plant exploded, it was operated with inadequately trained personnel.
Two Chernobyl plant workers died on the night of the accident, and a further 28 people died within a few weeks as a result of acute radiation poisoning. Large areas of Belarus, Ukraine, Russia and beyond were contaminated in varying degrees. There was an evacuation of about 135,000 people.
The Red Forest.
The second major plume of radiation released by the Chernobyl nuclear accident was carried directly over the Red Forest. Radioactive particles settled on trees, killing approximately 400 hectares of pine forest. The Red Forest is now one of the most contaminated habitats on earth. The Chernobyl nuclear disaster affected thousands of peoples lives, killed many people, wildlife and trees.
One of the first 1 000 megawatt nuclear plant was/went in service in 1973. In United states nuclear energy had been generating more electricity than oil had been in 1980's. However on April 26th there was a disastrous accident that accrued "Chernobyl Nuclear Power Plant Ukraine." From 1952 to 2009 there have been about 99 nuclear power plant accidents. These incidents have resulted as the loss of a human life or more then about $50 000 in property damage. But now in days nuclear energy is producing over the years.

THE PROCESS OF MAKING NUCLEAR ENERGY
A Huge power generater that can meet both industrial and city needs
It doesn't cause as much pollution as other power plants: emits less greenhouse gasses
Nuclear waste can be recycled
Nuclear waste can be recycled by three different levels:
1. exempt waste/Very low level
2. intermediate level waste
3. high level waste
Amount of radioactive wastes is very small relative to wastes produced by fossil fuel electricity generation
Used nuclear fuel may be used as a resource
Safe ways for the final disposal of high-level radioactive waste are proven
Can be expensive to reduce the possibilities of problems with radiation system
Has some unknown risks and high ones too
The construction time is very long (takes about 10 years to be built)
Where are the 10 largest Nuclear Power Plants?
10. Wintersburg, Arizona, USA
9. Fukui prefecture, Japan
8. Bruce county, Ontario, Canada
7. Little Cattenom, Lorraine, France
6. Little Paluel, Upper Normandy, France
5. Nord, France
4. Denieper River, Zaporozhye, Ukraine
3. Yeonggwang, South Korea
2. Niigata Prefecture, Japan
1. Fukusima, Japan
THANKS FOR LISTENING!!!!!
Almost a third of the world's energy is produced from Nuclear power plants
Nuclear power accounts for approximately 52% of Ontario's electrical energy source
There are 434 functioning Nuclear power plants in the world today
