Sky-high crude oil prices prod many governments from across the world to seek alternative energy sources other than petroleum, particularly in nuclear power.
This marks a major turnaround from the hitherto widespread anti-nuclear policies, which have been generally adopted after a series of disasters of the 1979 Three Mile Island accident and the 1986 Chernobyl catastrophe.
The United States now looks to license novel nuclear plants, putting an end to the nation's quarter-century moratorium on new nuclear facilities after the 1979 Three Mile Island debacle.
Other countries like France, Finland and China also follow the suit of the US and in related measures, some nations, including the Netherlands and Switzerland, watered down their original plans of scrapping nuclear power plants.
The Netherlands reversed its plan of closing down Borssele reactors and Switzerland voted down the draft of expelling nuclear plants on a phased basis.
In comparison, Korea is now suffering headwinds in expanding its dependence on nuclear power as amply demonstrated by its failure both in forging ahead with new reactors and finding a nuclear waste dump site.
Still the pros and cons continue to confront on nuclear power, which is efficient but has a potential detriment, with both sides not likely to find the same page any time soon.
Proponents point out the nuclear power technology emits virtually no airborne pollutants and overall far less waste material than fossil fuel-based power plants.
They also claim the controversial source of energy is much more cost-effective than other electricity-generating methods.
By contrast, opponents take issue with the radioactive products released by reactors into the environment and the irritatingly long period needed to decomposing the nuclear waste, hankooki.com reported.
Experts point out the spent nuclear fuel needs to be decayed for 10,000 years for it not pose a threat to health and safety. Nobody can ensure that the material can be safeguarded over such a long period of time.
All in all, anti-nuclear campaigners assert that both immediate and long-term safety concerns regarding the disposal of the nuclear wastes overwhelm any cost-related benefits.
Nuclear Power and Accidents
The world's first nuclear reactors were used to generate plutonium for weapons and the Soviet Union and western countries started to expand their nuclear research to non-military uses of atom from the mid-1950s.
In late 1951, electric power from a nuclear-powered generator was produced for the first time in the US, but the Soviet Union churned out nuclear power for commercial use first in 1954.
Other countries followed the Soviet Union and the US as relating technologies were further developed and the two-rounds of energy crises in the 1970s spurred a nuclear building boom across the world.
But On March 28, 1979 an accident took place, which moved the pendulum in disfavor of the nuclear power, at an American island called Three Mile Island (TMI) in Pennsylvania.
The TMI nuclear reactor suffered a partial core meltdown in early morning of the day and some scientists believe the radiation vented during the event.
Although no identifiable injuries due to radiation occurred (there is some opposition regarding the issue), it was a serious economic and public relations disaster and furthered a steep decline in popularity of nuclear power.
Mushrooming Nuclear Power Plants
However, things started to change in favor of the nuclear power as the crude oil prices sky rocket and the global regulations on green house gas emission become strict.
Oil prices have surged of late, threatening the energy security by cranking up the economic vulnerability to an oil price shock to many oil-importing countries like Korea.
The emission problems of fossil fuels are another stumbling block in sticking to the hitherto mainstream electricity source of the steam power generation.
Haunted by a scenario of extreme crude oil price volatility and the restrictions on greenhouse gas emissions in the power sector, the world started to tilt toward nuclear power again.
The US Department of Energy disclosed last November a pair of nuclear reactors would be established at North Anna, Virginia and also the Nuclear Regulatory Commission recommended a month later that the permit should be issued.
France where the nuclear energy source supplies up to 80 percent of the country's electricity recently said its state-owned utility would build a prototype next-generation nuclear plants.
France opted to pour three billion euros for the project, which will go ahead with the European Pressurized Water Reactor for 1,600-megawatt model by 2010.
The decision triggers Britain to rethink its nuclear option in the face of soaring oil prices, dwindling North Sea oil and gas reserves as well as setbacks in developing renewables.
The third nuclear plant is now under construction in the Olikiluoto region of Finland and China also plans to establish more than 20 nuclear reactors by 2020.
The Netherlands shelved its original plan of closing down Borssele plant and Switzerland reversed the draft of winding down nuclear power stations on a phased basis.
In a nutshell, economic benefits start to outweigh safety concerns of nuclear power plants in the above-mentioned situation change and the ripple effect is now being felt.
Korean Option
In the wake of the energy crises in the 1970s, Korea has desperately sought energy security policy to reduce its lopsided dependence on oils.
As the sixth-biggest nuclear power producing country in the planet, Korea today operates a total of 19 nuclear reactors, which combine to provide 40 percent of the nation's total electricity requirement.
According to the MOCIE, the country plans to install nine more reactors by 2015 with the aim of increasing the role of nuclear fission.
