What if we can’t get nuclear by 2021, what are the impacts?

As we know that, the benefits of using nucleur reactor as to generate electricity is more than using the fuel or some others. But some of the people are afraid when heard about nuclear. They are imaging that nuclear as a bomb which was destroyed the whole Hiroshima and Nagasaki. We sometimes need positive thinking in some condition of thing. If we always be in negative thinking, we will get trouble in the future and we will not get advancement..

Here, I'm list the benefit of using the nuclear reactor.. All of these are data from countries which already using the nuclear reactor actually in USA

Greenhouse Emissions Of Nuclear Power

There is world wide concern over the prospect of Global Warming primarily caused by the emission of Carbon Dioxide gas (CO2) from the burning of fossil fuels.

Although the processes of running a Nuclear Power plant generates no CO2, some CO2 emissions arise from the construction of the plant, the mining of the Uranium, the enrichment of the Uranium, its conversion into Nuclear Fuel, its final disposal and the final plant decommissioning. The amount of CO2

generated by these secondary processes primarily depends on the method used to enrich the Uranium (the gaseous diffusion enrichment process uses about 50 times more electricity than the gaseous centrifuge method) and the source of electricity used for the enrichment process. It has been the subject of some controv

ersy. To estimate the total CO2 emissions from Nuclear Power we take the work of the Swedish Energy Utility, Vattenfall, which produces electricity via Nuclear, Hydro, Coal, Gas, Solar Cell, Peat and Wind energy sources and has produced credited Environment Product Declarations for all these processes.

Vattenfall finds that averaged over the entire lifecycle of their Nuclear Plant including Uranium mining, milling, enrichment, plant construction, operating, decommissioning and waste disposal, the total amount CO2 emitted per KW-Hr of electricity produced is 3.3 grams per KW-Hr of produced power. Vattenfall measures its CO2 output from Natural Gas tobe 400 grams per KW-Hr and

from coal to be 700 grams per KW-Hr. Thus nuclear power generated by Vattenfall, which may constitute World's best practice, emits less than one hundredth the CO2 of Fossil-Fuel based generation. In fact Vattenfall finds its Nuclear Plants to emit less CO2 than any of its other energy production mechanisms including Hydro, Wind, Solar and Biomass although all of these processes emit much less than fossil fuel generation of electricity.

Powering of the economy

Since the oil embargo of 1973, Americans have used energy more wisely and more efficiently. During this time, our population has grown from 211 million to almost 280 million, our economy has grown about 50 percent, but our use of energy has grown only 10 percent. But our economic growth, however, has been fueled largely by electric power.

Between 1973 and 1990, our GDP, which is the measurement of a nation's wealth, grew by about 50 percent. In the same period, electricity use grew by 58 percent. From this information, we can conclude that in order to m

eet the needs of our strong economy and our growing population, we must have reliable supplies of electric power. The nation's nuclear power plants produced 674 billion kilowatt-hours of electricity in 1996. This was m

ore electricity than the entire country consumed in the early 1950s. Worldwide, there are 442 nuclear power plants at work, contributing about 19 percent of the world's electricity supply.



Reduction of dependent on oil

At the time of the 1973 oil embargo, oil accounted for about 17 percent of US. electric supply; nuclear energy was about 5 percent. In 1990, however, oil represented only about 4 percent of U.S. electric supply, while nuclear energy accounted for about 21 percent. Consequently, the U.S. imports 20 million barrels less of oil each year. For example, since l973, nuclear energy has displaced 4.3 billion barrels o

f imported oil and reduced our trade deficit by $12 billion. This decrease in our trade deficit causes a direct increase of our Gross National Product, which is also measure of a nations wealth.


World Wide

More than 400 nuclear power plants are operating in 25 countries around the world today, supplying almost 17 percent of the world's electricity. In most co untries, nuclear energy plays an even larger role as a source of electricity than in the United States. Many of these nations are building new nuclear energy plants to meet the needs of their growing populations and expanding economies. About 83 new nuclear energy plants are currently being built around the world

Conclusion

Overall, nuclear energy has proven to be most beneficial to our society. As a result of this technology, the United States has decreased its dependency on foreign-imported oil. In fact, the United States saves about 12 billion dollars each year through the lack of oil it imports from other nations. Nuclear energy has also proven to be a protector of the environment because of the lack of CO2, greenhouse gasses, and other gases it emits into the atmosphere. There are, however, some major drawbacks to using nuclear energy. These drawbacks include the actual safety of using nuclear energy, the waste it produces, and the atomic weapons that nuclear energy promotes. Overall, however, we believe that the use of nuclear energy greatly outweighs any other source of energy..

So, what we wait for? wait until our life cost become increasing continuously?or wait until our development will get negative effect from the increasing of fuel price? or wait until the global warming become worst? So, everyone can think as good as possible what our country needs.
