  4. 4. 2. INTRODUCTION • 11th March 2011, magnitude 9 earthquake. • Fukushima tsunami. plantstruck by the following • Reactors lost cooling ability too much pressure. • Consequence: release of radioactive steam (impossibility for humans to stay there to work for a long time). DrMartínezLirola Academic year 2013-2014 English studies, English Language III University of Alicante
  5. 5. 2. INTRODUCTION • Various attempts to cool the radioactive fuel: -Water poured by helicopters -Water poured by canon trucks • UNSUCCESSFUL Since then, struggle to deal with the problems (water pumped in the contaminated reactors.) -But several radioactive leaks • Danger of radioactive water leaking into the Pacific Ocean.

  14. 14. 5. NUCLEAR ENERGY: ADVANTAGES - Economic advantages: ● It employs more peoplethan other forms of energy (gas, coal…) ● Uranium needed in small amount and cheaper ● Transport is cheaper for Uranium than for others fuels DrMartínezLirola Academic year 2013-2014 English studies, English Language III University of Alicante
  15. 15. 5. NUCLEAR ENERGY: ADVANTAGES - Nuclear energy requires a small production surface -The price of uranium is very stable, unlike fossil materials. Cheaper energy ensured. - Ecologicadvantages: ● Nuclear production does not emit CO2 ● Natural resources of the planet are becoming scarce => Nuclear = good alternative.
