Is Nuclear Energy Answer to the Energy Crisis by Albert You

Is thermo thermo atomic force play the answer to the competency crisis? Submission Date 29/8/2012 needful Length 1250-1500 Actual Length 1291 Introduction It is frequently said that thermo thermo thermo thermonuclear energy is cheaper, safer and more efficient than fossil fuels, and without the effects on oxygenize pollution, so it is often seen as a solution to the energy crisis. In 2000, approximately a sixth of the global electricity advocator was provided by nuclear power. Boyle, G et al 2003) However, over the last year, there has been the hard accident with a nuclear power base in Japan, which has hunt attention on the nuclear issue once again, as it recalled the ravage happening of Chernobyl, Ukraine in 1986. It needs to be asked whether it is safe enough to be the answer to the energy crisis. From my perspective, exploitation of the nuclear energy produce through with(p) more harm than good so removed. Therefore, how to approach the role of nuclear power in thi s energy crisis in future is the highest priority.Environment According to the sustainable Development commission (2006), there is no energy technology end reach zero carbon emissions currently. Even renewable technologies will scat to carbon emissions during construction. Nuclear power plants are no different. With large call for of product of cement and metal during construction, mining the uranium ore, massive energy inputs on forsakes disposal and the uranium enrichment facility, nuclear energy is definitely non green energy like concourse say so.Moreover, as the spin- saturnine during the uranium enrichment processes, HCFC (hydro chlorofluorocarbon), the major(ip) contributor of depletion of the ozone layer in the f number atmosphere, which more or less discharged to the atmosphere though aft(prenominal) treatment. Due to the limitation of efficiency, approximately 33% heat utilization proportion (From IAEA 2012), the light water reactor demand, a large amount of dis sipation heat are discharged by nuclear plant .For typic nuclear systems, in order to ensure that the effects of temperature rise in the environment is small, a large amounts of water (around a billion gallons per day) moldiness be passed through the steam condenser to cool down them ,which as well is the main reason why the nuclear plants built near the ocean or water area . Heater water can have adverse effects on the plant and animal life which dexterity brass instrument a great variation among species. ( Murray, R 1980) All nuclear plants generate dangerous nuclear wastes.Nuclear wastes contain radioactive material which is insecure to most forms of life and the environment. Some nuclear wastes remain dangerous for thousands of geezerhood. When biological tissue expose on radiation or touch radioactive material, energy is deposited and a series physical changes make believe place that cause great damage on the cells to variation or death. Current major approaches to man aging nuclear wastes are segregation, storage and deep burial for a tenacious time according the different risk level of wastes.There are round cases about leak of wastes, and few communities are willing to accept waste site near them. (Gore, A, 2009) Cost and thriftiness If only considering the unit toll of producing electricity by the nuclear power comparing other forms of energy, it is seems to be cheaper much from the data (World Nuclear Association, 2010). However, building a new nuclear plant is a tremendously complicated project that addresss huge investment and takes many years to complete. It is no likely to calculate the perfect cost of a new nuclear power plant claimed by the Sustainable Develop Commission.Helen Caldicott (2010) believes that the real economy value of nuclear pains is neer carefully analyzed, including the cost of uranium enrichment, financial claims later on the nuclear disaster, construction and decommission. It is a fact that a smaller proporti on (approximately 26%) of fuel cost accounts for a nuclear power plants whole operating cost than other types of power plants. However, the high cost of waste disposal remains a big headache since advent of nuclear technology .According to the mail online news, the cost of cleaning up Britains nuclear waste has increased to almost ? 48 billion, it was revealed today as the political science unveiled radical changes to managing the countrys nuclear legacy. The cost of the programme was estimated at ? 43 billion last year but it has soared to ? 47. 9 billion. (2012). A boost problem is that nuclear power plants must maintain higher standards of in operation(p) condition in case of the likelihood of potential safety loopholes of equipment in poor condition.In addition Employees, administration, and supplies cost a nuclear power plant $0. 0137 per kWh on average in 2008. (Morgan J, 2010) Going back to the nuclear disaster cause by earthquake-tsunami in Fukushima, the government of Ja pan estimates the cost at $300 billion, which would make it the most expensive natural disaster on record, according to Birmingham L (2011). JP Morgan has estimated the Tokyo electricity company whitethorn face claims of up to 2 trillion yen, nearly 15 billion pounds by the end of this year.As to the subsequent expenditure of Chernobyl disaster, in Ukraine, 5-7 percent of government outlay each year is still devoted to Chernobyl- link up benefits and programmes. In Belarus, total expending by Belarus on Chernobyl between 1991 and 2003 was more than US $ 13 billion. condom and Accidents The most important part of public concern is the safety of nuclear plant. Regardless of how many wisdom man have, human being never can bear the disastrous results once nuclear accident take place.Huge loss in economy, irreversible damage in environment and unheralded effects on future, all of these prove the nuclear power have not meet the contemporary safe needs. With the last one nuclear power station closed in March 2012 in Japan, which agent the all of the Japans 50 reactors have been taken off line, marking the countrys first no nuclear power day since May 1970. And after Fukushima disaster, under the pressure of anti- nuclear protests, Germanys compaction government has announced a reversal of policy that all the countrys nuclear power plants will be phased out by 2022.Twenty five years on, the disaster at Chernobyl casts a long shadow over the people. As the most serious nuclear disaster on history , Chernobyl disaster, which proceed directly to thirty one deaths in that accident . About 200,000 people had to be permanently migrated after the disaster. According to IAEA report, up to 4,000 people may die from long-term diseases related to the accident. Those numbers are a payoff of debate. The World Health Organization reported the actual number of deaths related to Chernobyl was about 9,000. However, when atastrophe happened in Fukushima, in Japan, this tragedy makes people realise the howling(a) hazard of nuclear power once again and the fear is far more than the loss. There have been over 25 indirectly deaths or cases of radiation indisposition from the nuclear accident, over 100,000 people had to be evacuated from their homes. In this day and age, for terrorists, nuclear power plants are obvious targets. (Caldicott, h, 2007) Assault by hijacked plane, truck bombs, or covert attack into the reactors govern room, which are very likely happened in the future. Once breakout of war, nuclear plants also are first military targets.The subsequence of meltdown or destroy of reactors could trigger the countless death of people in severely populated areas, and they would suffer slowly and painfully from acute radiation sickness year after year, cancer, leukaemia, congenital deformities, or genetic disease. Conclusion In conclusion, it is clear from the preceding arguments that the weakness overweighed the advantages in nuclear power use, consi dering the impacts of the undecipherable power to the environment, huge cost of upfront investment and reconstruction after disaster and the unknown safety hidden risk.Owing to this, people should take the nuclear power seriously because of the nuclear disaster would not be bitter by human race. Hence, the each governments should not promoted the nuclear power as the answer to the energy crisis.
