Against Nuclear PowerFor Nuclear Power A compromised reactor core can be dangerous Meltdowns can be fatal! Radiation leaks can cause death to people in the community The safety precautions are very expensive Nuclear Power is not renewable Uranium But there are precautions that prevent reactors from becoming compromised But… Nuclear Power is one of the safest energy forms thousand people die each year from Respiratory disease 300 are killed in mining accidents No Americans have seriously been injured or killed from Nuclear Power Nuclear Power is sustainable
In the 1990’s Nuclear Power was the fastest growing energy source In 2005 it was the slowest! m#adv lant_cattenom_by_dralzheimer.jpg
Located near Harrisburg Was classified as a partial meltdown The facility did not have enough coolant to supply the core. The radioactive mass never made it past the steel outlining in the containment structure The special concrete put in as an added precaution gave the workers at Three Mile Island enough time to stop the disaster.
Located in the Ukraine In 1986 the worst case disaster took place A fire destroyed the casing of the core Released radioactive isotopes into the atmosphere Death toll 31 died initially 15,000 died later as the result of the radiation
Waste Disposal The byproduct of fission remains radioactive Storage facilities are not sufficient to store the world’s nuclear waste Transportation of the waste can be risky Radiation Can cause cancer, radiation sickness, and genetic mutation
Nuclear Power is not renewable It is sustainable but the Uranium needed to power nuclear plants in limited Similar to the issue related with fossil fuels. The reality=nuclear power is clean And the power plants don’t require huge amounts of uranium. It seems like a viable option as an alternative form of energy. effects.html
Radiation is naturally present in our environment It is artificially produced by X-rays and by Microwaves Humans have defense mechanism against many types of damage caused by radiation Our bodies are not helpless The effects radiation can have on our bodies It can injure of damage cells Cells can die Cells can incorrectly repair effects.html
Radiation doses of 200 rems can cause radiation sickness Only if we receive a large amount all at once If we used nuclear power we would only receive an extra 2/10 of a millarem each year Even if there was an accident there are safety precautions taken to ensure the safety of the surrounding community
The pressure vessel is surrounded by a thick concrete wall This is inside of a sealed steel containment structure Which is inside of a steel reinforce concrete dome that is 4 feet thick There are sensors on the dome to detect changes in radiation and humidity
Public demand for safety precautions are on the rise. The nuclear fuel cycle is a popular target for terrorists It can also be a pathway leading to nuclear weapons Storing nuclear waste is problematic, and the storage facilities the U.S. has are being filled International demand for nuclear energy is growing dramatically. energy/index.html
The U.S. government needs to deal with a broad range of threats to the public. These security concepts are not limited to U.S. soil but need to be global in nature. With the heightened fear of terrorism in the United States the government needs to ensure people that there is limited danger in order to develop nuclear power. energy/index.html
Since the Atomic Bomb dropped on Hiroshima people have been afraid of what nuclear power could lead to Over 10,000 people were killed in Hiroshima Many countries have nuclear weapons Ex) the US and Russia Many are working on developing them N. Korea, S. Africa, India, Iran, Iraq… s.html
Reactors produce radioactive waste Which is dangerous because it can kill humans who come into contact with this waste The U.S. plans to move its nuclear waste to an underground storage facility in the year s.html /Rad-symbol%20(Big).JPG
England is already dependent on nuclear power Japan will soon be dependent upon Nuclear Energy The U.S. has a total of 110 nuclear reactors Nuclear power has to potential to supply the U.S.’s energy needs
Water Consumption The harvesting of Uranium can consume large amounts of water For example, the Roxby Downs mine in South Australia uses 35 million liters of water each day Waste Heat The heated water from cooling down the rods is discharged into a local river or lake. In some cases this heat increase can effect the behavior of fish and aquatic life.
Other waste Other waste, such as gas, liquid, and solid waste produced through the process of purifying the water through evaporation. High Level Waste The waste from a power plant still contains radiation and can be harmful to the environment
Severe environmental contamination is possible when a nuclear accident occurs. The Chernobyl accident released large amounts of radioactive contamination, killing many and rendering an area of land unusable to humans for an indeterminate period. The habitability of the area for animals, however, has been less clear. Some researchers have claimed to have detected reduced numbers of insects and spiders, while others have claimed that wildlife has flourished due to the absence of humans.
Very few political problems regarding nuclear power exist. The main being that a nuclear power plant makes a prime target for a terrorist attack as a meltdown would create large scale damage.
% of electricity of world power came from nuclear power Development increased from 1960 to about 1985 production increased then leveled off A clean reliable energy source to use but start up costs are a lot 6-10 billion, most efficient way would just run the power plant as long as possible and possible add onto the power plant USA's nuclear power plants are already about 98% efficient
Most countries cant afford to get enough funding to set up a power plant in an ideal location Nuclear waste disposal is a current problem now Safely transporting waste to locations can cause problems Mining it can be costly and can hurt the environment by extracting uranium from underground
Would be helpful in the long run but the cost to build and operate would be a problem Like developed countries waste disposal is still a problem It wouldn't be able to help a place like Africa because of the weak economy Mining for the Uranium would be a problem for an undeveloped country ; finding where the uranium is and extracting it might be hard

The design life for nuclear power plants is suppose to last 30 to 40 years. - Most that exist now have been operating for about 20 or more years. (www.iaea.org) Many people want to do away with nuclear power. However it is here to stay. (www.energy.gov)
