NUCLEAR POWER VS COAL POWER

Hi.What we have learned so far about the nuclear energy in the class,we do not see any cons for nuclear power. Therefore I will tell you the advantage of nuclear power.Nuclear power is the cheapest ways to produce electric power. The generation cost ($/kWh) is definitely  less than the other technologies of electricity generation . We cannot do comparison between nuclear power and  hydraulic power. Everybody can build a nuclear reactor to anywhere they want. However,coal fired plant must be built close to coal mines and a dam can only be built to a very specific place at a river basin.

The cost of generation includes capital cost. The capital cost = interest paid for the load + operaton + maintance cost  + the fuel cost

 Nuclear power plants use small amount of land. The other alternatives need more land than NPP.For example,solar or wind need many times more land to generate similar power.The exhaust gases from fossile fired plants contain CO2. Currently,there is no way to get rid of CO2. This gas is main contributer of temperature increase in our life. Coal consist of sulphur and when burned, SO2 is produced. This gas causes acid rains. The cost of electricity will increase although of the sulphor can be scrubed from the coal while or after the combustion.We must remember,if the burners operate at high temperatures, like in gas turbines and diesel  engines, nitrogen oxides will be generated. This gas is causes of the ozone depletion in the atmosphere.The other info is,the ash from a fossile fired plant accumulates around the power plant as ash mountains.Ash contains toxic elements just like cadmium and radioactive elements (uranium and thorium).

Nuclear power produced very little amount of highly radioactive waste. The toxicidity of this waste dissapear with time.Nuclear enery gives energy independence to a nation.
The nation that do not dependent to foreign energy resouces have  free hand in diplomacy considering the strings attached to gas and petroleum sales in the international markets.

  1. how about the energy produced by sugar which can be used to replaced the fuel?is it can be consider nuclear power plant?

  2. Nurul,so far we need to do further research regarding to your opinion..and for your info,nuclear power plant only using uranium pallet as its fuel because of high heat will be generated through of fission..

  3. If world start using energy produced by sugar, we wont able to buy 1kg sugar for rm2 anymore :)
