Hello there, we're Zhi Xin, May and Kanyaw and in this blog, we aim to talk about the most popular scientific breakthrough - the Nuclear Energy and if Singapore should explore this energy option in the near future.

Without a doubt, we hope that you would support us in our humble opinion with regard to Nuclear Energy usage in Singapore.

Weighing the scale





PROS


  • -Produce no soot and greenhouse gases(Clean atmosphere, cause no global warming) in power generation
  • -Reduce Carbon Dioxide in the atmosphere
  • -Provide much more energy than fossil fuels.
  • - low operating cost
  • - Large power generating capacity
  • -Little fuel needed ; long-term usage- less vulnerable to shortages of fuels
  • - Safest methods of producing energy
  • -Low fuel cost

Nuclear Energy(pg 144,145)




Cons
  • Building the nuclear plant requires massive amount of cement and other construction materials

  • The production and transportation of materials to the plant site release large amounts of carbon

  • Nuclear power requires high-grade uranium

  • Estimated to be enough for 60 to 70 years at current rates of generation.

  • Once high-grades uranium are gone, we need to use low-grades uranium which need more energy, that will produce carbon emissions

  • When the nuclear plant reaches end of life, it must be carefully dismantled (the process release carbon again)

  • Adding up all the amount carbon released, it will equal back to same amount as wind-produced energy and that’s only if the high-grade uranium is available

  • If high-grade uranium is gone, carbon released will equal back to carbon released by the natural gas-fired power plants

  • Nuclear power plants require more water than coal-fired power plants( Water used for cooling, warm water won’t do the job)

  • It’ll be a problem if the world becomes a drought-stricken,warmer world

  • Solar & wind-generated electricity only require minuscule amount of water

  • Nuclear energy creates radioactive waste that will remain deadly for eons which must be transported to a repository

  • Nuclear power plant is likely to be targeted by terrorists

  • Authorities would have to worry about the materials found in nuclear power plants as people can create weapons for mass destruction
