Nuclear Energy

  1. 1. Nature of Energy Energy is all around you!You can hear energy as sound.You can see energy as light.And you can feel it as wind.
  2. 2. Forms of Energy The five main formsof energy are:HeatChemicalElectromagneticNuclearMechanical
  3. 3.  Nuclear energy originates from the splitting of uraniumatoms in aprocess called fission. At the power plant, the fissionprocess is used to generate heat for producing steam,which is used by a turbine to generate electricity. The energy released by nuclear reaction is called nuclearenergy.
  4. 4. Brief History Nuclear energy was first discovered in1934 by Enrico Fermi. The first nuclearbombs were built in 1945 as a result ofthe infamous Manhattan Project. The firstplutonium bomb, code-named Trinity, wasdetonated on July 16, 1945 in NewMexico. On August 6th1945 the firsturanium bomb was detonated overHiroshima. Three days later a plutoniumbomb was dropped on Nagasaki. There isover 200,000 deaths associated withthese detonations. Electricity wasn’tproduced with nuclear energy until 1951.
  5. 5. e=mc2Nuclear energy is released from the nucleus of an atom. Nuclear reactions likefusion (when two atomic nuclei comb into form a single heavy nucleus) andfission (w hen a single heavy nucleus splits into two smaller nuclei), releasevery high amounts of energy. The mass of an atom gets converted into energy.Einsteins famous equation helps to calculate the amount of energy releasedduring a nuclear reaction. This equation is given as:
  6. 6. Nuclear Energy The nucleusof an atom isthe source ofnuclearenergy.
  7. 7. Nuclear Energy When the nucleus splits (fission),nuclear energy is released in theform of heat energy and lightenergy. Nuclear energy is also releasedwhen nuclei collide at high speedsand join (fuse).
  8. 8. Nuclear EnergyThe sun’s energyis produced froma nuclear fusionreaction in whichhydrogen nucleifuse to formhelium nuclei.
  9. 9. Nuclear Energy Nuclearenergy is themostconcentratedform ofenergy.Most of us live within 10 miles of the SurryNuclear Power Plant which converts nuclearenergy into electromagnetic energy.
  10. 10. Nuclear energy is one of the safest energies that can be used to achieve many desiredresults, provided its used safely with due precautions. It can be used in diversified fieldsfor peaceful purposes such as electricity generation, medicinal purposes, reducingpollution, etc. Heres an elaborate explanation about its benefits.
  11. 11. Advantages Very small amount of raw materialis required
  12. 12. Advantages Very small amount of raw materialis required Very less amount of pollution
  13. 13. Advantages Very small amount of raw materialis required Very less amount of pollution Cheap electricity
  14. 14. Advantages Very small amount of raw materialis required Very less amount of pollution Cheap electricity Waste produce is also small
  15. 15. Advantages Very small amount of raw materialis required Very less amount of pollution Cheap electricity Waste produce is also small Save environment because of notcreat green house effect
  16. 16. Advantages Very small amount of raw materialis required Very less amount of pollution Cheap electricity Waste produce is also small Save environment because of notcreate green house effect
  17. 17. Advantages Very small amount of raw materialis required Very less amount of pollution Cheap electricity Waste produce is also small Save environment because of notcreate green house effect Easy transportation
  18. 18. Advantages Very small amount of raw materialis required Very less amount of pollution Cheap electricity Waste produce is also small Save environment because of notcreate green house effect Easy transportation Grow Indian economy
  19. 19. Economic Advantages The energy in one pound of highly enrichedUranium is comparable to that of one million gallonsof gasoline. One million times as much energy in one pound ofUranium as in one pound of coal. Nuclear energy annually prevents 5.1 million tons ofsulfur 2.4 million tons of nitrogen oxide 164 metrictons of carbon First commercial power plant, England 1956 17% of world’s electricity is from nuclear power
  20. 20. Nuclear power is definitely a boon. Not consider the negatives only. When we think about theuses of nuclear energy the bad effects are very negligible. In our earth we live because ofnuclear energy. The climate in earth surface is the reason for the generation of life in earth.The rays coming from sun is the reason for this climate. We know nuclear fusion is theprocess in sun. Nuclear fusion of hydrogen is the generator of energy produces in sun. Inthis point of view we can say that nuclear energy is a boon.Nuclear energy is used in many useful sections like power plants, submarines etc...The costof electricity produced by nuclear fission in nuclear power plants is low compared tothermal power plants. We can produce more electricity from a small area through nuclearpower plants. The modern technology can stop the radiation effect of the nuclear powerplant effectively. So nuclear power is good for human life
  21. 21.  Nuclear power is a best power resource in todaysenvironment .As every coin has two sides so there is also thereare two sides of Nuclear power plant one is good and other oneis bad .Today nuclear energy is seen as a future option forenergy and it is a good energy option in real but when it is usedwith care.
  22. 22. Economic Benefits of Nuclear Power Nuclear power plants provide low-cost, predictable power atstable prices and are essential in maintaining the reliability of theU.S. electric power system. Nuclear power is a major nationalenergy source. Nuclear energy is our nations largest source ofemission-free electricity and our second largest source of power.The 103 U.S. nuclear units supply about 20 percent of theelectricity produced in the United States. The only fuel sourcethat produced more electricity was coal.
  23. 23. Environmental benefitsOf all energy sources, nuclear energyhas perhaps t he lowest impact on t heenvironment especially in relat ion t okilowat t s produced because nuclearplant s do not emit harmf ul gases,require a relat ively small area, andef f ect ively minimize or negat e ot herimpact s. I n ot her words, nuclearenergy is t he most "ecologicallyef f icient " of all energy sources
  24. 24.  Nuclear power plants have long periods of operation. Nuclearpower plants are designed to operate continuously for longperiods of time. They can run about 540 days before they areshut down for refueling. The longest continuous run by a lightwater reactor is Three Mile Island, Unit 1, in Pennsylvania,which completed a 688-day run. The longest run of any type ofreactor is 894 days, achieved by the Pickering 7 plant, a heavy-water reactor in Ontario, Canada (Canadian CANDU reactorscan be refueled while operating).
