then and now
Then and Now
  • 1954: USSR’s Obninsk Nuclear Power Plant
  • Nuclear capacity started at 1 GW (gigawatt) and quickly rose to 100 GW in the late 1970’s.
  • In the1980’s, nuclear power increased much more slowly
  • In 2007, 14% of the world's electricity came from nuclear power, despite concerns about safety.
  • 63 nuclear units were cancelled in the USA between 1975 and 1980.

Can energy production from nuclear energy be enhanced

in areas already producing it?

  • new ore discoveries and advanced mining techniques could increase the production of nuclear energy
  • even though other countries have the potential to increase nuclear power, over 80% of the future’s nuclear power will come from countries already using nuclear power
  • currently producing countries such as Japan, the United States, and France have the potential to use much more nuclear power than before
  • capacity for nuclear power for already-producing countries in 2008 was 367 GW, but could increase to 9137 GW by 2100
ability to enhance nuclear power overall8
Ability to enhance nuclear power overall
  • Can energy production from nuclear energy be developed in those areas where it has not yet been developed?
  • New ore discoveries and advanced mining techniques could increase the production of nuclear energy
  • Countries currently uninvolved in nuclear power have the potential to generate 999 GW by 2100
environmental issues
Environmental Issues
  • What environmental problems does nuclear energy pose?  Are those problems real or exaggerated?
  • overall, it is clean energy
  • nuclear energy doesn’t produce carbon dioxide or give off other greenhouse gases
  • little waste is produced
  • the waste that is produced is highly dangerous and radioactive
    • must be stored away
    • when buried underground, it causes damage to the surrounding environment and the inhabitants
    • must be kept away from earthquakes and floods

social political problems
Social/Political Problems
  • High initial investment cost –somewhere between $6 and $9billion.
  • Uranium has to be mined.
  • Only 3% of uranium is used out of the rods used to power the reactors.
  • At current consumption rates the minable uranium will last only 100 more years.
  • 2/3 of energy produced goes off as waste heat.
  • Droughts can pose a problem, because reactors need lots of water for cooling.
social political problems12
Social/Political Problems
  • A nuclear power plant produces 3 cubic meters of spent fuel each year.
  • The spent fuel contains actinides which remain radioactive for a long time.
  • We do not have a way of disposing of radioactive waste.
  • There is a continuous threat of radioactive contamination.
  • A nuclear power plant could have a meltdown, which is when fuel rods overheat and basically melt down and contaminate everything.
laws and regulations
Laws and Regulations
  • The U.S. environmental protection agency is concerned with the amount of radioactive waste that is produced. (50,000) metric tons as of 2007)
  • The U.S. Department of Energy has a program that promotes secure, competitive, and environmentally responsible nuclear technologies to serve the present and future needs of the United States and the world.
  • The U.S. Nuclear Regulatory Commission also regulates nuclear energy in the United States, and promotes nuclear security.
  • There are lots of other organizations that promote safe nuclear practices such as the American Nuclear Society, Canadian Nuclear Society, etc.
  • Organizations such as the World Nuclear Association, World Nuclear University, and World Nuclear News, help research and educate people on nuclear energy. As well as promoting safe nuclear practices.
