The Benefits Of Nuclear Energy

Register to read the introduction… Current conventional thermal nuclear reactors around the world in total consume about 70.000 tons of uranium per year. Uranium is widely distributed around the world and in total we have about 3851 million tons. Which can amount for 55 years of supply, and if we consider hypothetical reserves the lifespan of uranium becomes 200 year. This doesn’t differ much from the fossil fuels: In total lifespan coal is expected 200 to 400 years for example. There are plans to develop recycling nuclear reactors: breeder reactors and depending on the rate of nuclear energy use we could need them by 2050. What breeder reactors do is improve the efficiency of the reactors, which currently stand at 2% to 75 or more and this could significantly raise the lifespan of uranium to eighty thousands of …show more content…
To understand whether nuclear energy is going to be sustainable in the long term, however, several points have t be considered: fossil fuel prices, the value attached to reducing emission in fossil fuel plants , the technological development of nuclear energy and renewable and the safety measures needed for nuclear …show more content…
For example; in the USA these costs rose at a rate of 13% between 1980 due to more requirements and scarcity of the sites. If safety related costs were to persist they could severely hider the economic sustainability of the nuclear energy.
The energy supply of hydropower stations is the water passing through dams. And this is a limitless supply, because hydropower plants take advantage of the hydrologic cycle. As the sun heats up the water it evaporates into the air the sun heats up the air which rises up in the atmosphere where the temperature is low. Along with the air water vapor also rises. And once the temperature drops low enough these become water droplets which then precipitate by the effect of gravity. Because of the hydrologic cycle water can collect upstream which is what generates the electricity supplied by the hydropower plant.
Hydropower plants do no t emit gasses like fossil fuels and they do not emit carbon however they emit methane- indirectly. Methane is a green house gas much more powerful than carbon dioxide. The methane originates from the decaying organic matter caused by the flooding the dam creates. The decaying it’s at its highest at the begging of the flood and it gradually decreases. The amount of methane emitted depends on the ecosystem and the
