Tag Archives: how nuclear power affects the environment

To understand why the Germany became the first develop country to take action and start shouting down the nuclear program they have, we have to take a look on the history of nuclear in Germany. We all know until 1989 there was two Germanys the east and the west.

West Germany:

The nuclear program start at 1950s, however the first reactor opened in 1960 in Kohl am Main and it was an experimental nuclear power station. All of the German nuclear power plants that opened between 1960 and 1970 had a power output of less than 1,000 MW and have now all closed down. The first commercial nuclear power plant started operating in 1969. Obrigheim, the first grid station, operated until 2005. (Neckarwestheim). A closed nuclear fuel cycle was planned, starting with mining processes in the Saarland and the Schwarzwald; uranium ore concentration, fuel rod filling production in Hanau; and reprocessing of the spent fuel in the never-built nuclear fuel reprocessing plant at Wackersdorf. The radioactive waste was intended to be stored in a deep geological repository, as part of the Gorleben long-term storage project.

East Germany:

The first nuclear power plant in East Germany was Rheinsberg Nuclear Power Plant and they shutdown in 1990. The second to be commissioned, the Greifswald Nuclear Power Plant, was planned to house eight of the Russian 440 MW VVER-440 reactors. The first four went online between 1973 and 1979. The other four were cancelled during different stages of their build-up. In 1990, during the German reunification, all nuclear power plants were closed due to the differences in safety standards. The Stendal Nuclear Power Plant, which was under construction at the time, was cancelled.

Also Germany had three accidents. The first was in 7/12/1975 the locution was Greifswald, East Germany. Electrical error causes fire in the main trough that destroys control lines and five main coolant pumps, almost inducing meltdown. The second was in 4/5/1986 in Hamm-Uentrop. Operator actions to dislodge damaged fuel rod at Experimental High Temperature Gas Reactor release excessive radiation to 4 km2 (1.5 sq mi) surrounding the facility. The third was in 17/12/1987 in Hesse. Stop valve fails at Biblis Nuclear Power Plant and contaminates local area.

In 8/3/2011 the Germany government shutdown 8 nuclear plant in plan to take the nuclear power aout of the picture completely in 2022.Befor they shut down the plants the nuclear power was accounted for 23% of national electricity consumption. The announcement of the plan  was first made by Norbert Röttgen, head of the Federal Ministry for Environment, Nature Conservation and Nuclear Safety, after late-night talks.





In 1957 the Korean decides to join International Atomic Energy Agency not because they like the nuclear power but because they do not have enough fossil fuel resources. And for all of you out there routing against nuclear power here an example of what can the nuclear power delver and the other source of power cannot. So in 1962 Korea’s first research reactor achieved criticality. Since 1978 nineteen reactors were bulled that’s make total of  four with CANDU and the other sixteen with PWR technology. The first Korean reactor was kori-1 and it was built almost entirely by foreign contractors. Since then the KSNP (Korean Standardized Nuclear Plant) had developed and from 1995 until now they use 95% of their owned technology in building new nuclear reactors. Also in 2010 they went international by   impressing the United Arab Emirates and made their first export order of four APR1400 reactors. Also they were the first country to open a nuclear safety school.


Nuclear plants in South Korea

The total electrical generation capacity of the nuclear power plants of South Korea is 18.5 GWe from 21 reactors. This is 29.5% of South Korea’s total electrical generation capacity, but 45% of total electrical consumption. The South Korean nuclear power sector maintains capacity factors of over 95%. Despite the March 2011 Fukushima nuclear accident, South Korea remains a strong supporter of nuclear power. In October 2011, South Korea reconfirmed its position as a strong supporter of nuclear power with the hosting of a series of events to raise public awareness. The events were coordinated the Korea Nuclear Energy Promotion Agency (KONEPA) and included the participation of the French Atomic Forum (FAF); the International Atomic Energy Agency (IAEA); as well as public relations and information experts from countries that utilize or plan to utilize nuclear power.[1]

Nuclear energy; is it environmental friendly or is it not? This debate has been solely planted after the world witnessed the effects of major nuclear meltdowns on the environment. However, many have made the elementary mistake of overseeing the clear advantages that nuclear power generation hold over the likes of coal and natural gas power generation. Pessimists often fall back on the notion that nuclear meltdown will spell fatal for the environment and nuclear power plants operating throughout the world would sooner or later give way, resulting in environmental catastrophe. But then again, nuclear meltdowns occur only in the steepest of circumstances. Blinded by the advancement in nuclear technology and the availability of various nuclear meltdown defense mechanisms developed throughout the years, many continue to speculate brashly about how nuclear power affects the environment.

The Japan nuclear meltdown

The best way to go about this issue is by doing an in depth comparison between the most widely used power source which is natural gas and coal, and what could be considered its best alternative, nuclear power. These two types of power generation are understood to produce the highest amount of power in the world as compared to the greener substitute that is renewable energy. In Malaysia, natural gas and coal is understood to produce around 95% of the total energy mix. To put this into retrospective; due to the abundance in resources of coal and natural gas throughout the world, much of Malaysia’s energy is drawn from these resources.

The biggest problem with natural gas and coal (fossil fuel) is excessive pollution. Coal-fired plants spew out CO2 and toxins like nitrous oxide and sulfur dioxide. The cumulative greenhouse effects promise catastrophic weather phenomena, widespread flooding, food shortage, displacement, and extinction. The effect of rise in temperature contributes to global warming. Agriculture is very sensitive to climate and hence is heavily affected, requiring shifts in crops that cannot be grown in different areas. Livestock are also affected and face difficulty especially in breeding and various forms of diseases caused by radioactive emission. Eventually, the melting glaciers will cause sea levels to rise which will result in loss of habitat land, allows inland penetration of salt water which heavily impacts aquatic life. Burning fossil fuel also produces sulfur dioxide, a gas that contributes to acid rain. Acid rain is destroying forests, making lakes unlivable for fish and degrade ecosystem.

The whole process of mining coal can be difficult and dangerous. Coal mining requires large amounts of strip mining which eventually destroys large areas of the landscape. Waste disposal for coal-fired power plant is a major issue. Coal-fired power plant produces large quantity of ashes and extreme amount CO2, which is difficult to contain. It destroys and pollutes large areas of land. Dust is also generated, causing health problems to human being and eloping plant surfaces. Based on this, it can be stipulated that natural gas as well as coal-fired plants are the catalyst to global warming.

Nuclear energy on the other hand produces minimal or negligible amount smoke or CO2, so it does not contribute to the greenhouse effect. For the abundance of energy nuclear power plants is capable of generating, it has always puzzled many that the whole process emits only an insignificant amount of CO2. Well, this is just one of the great benefits of nuclear power. In every sense of the word, nuclear energy is definitely ‘eco-friendly.’ Thus ‘global warming’ process can be minimized. Nuclear power in no way changes the earth’s climate, which means that there will be no acid rain which is lethal to the environment. Acid rain contains high amount of toxins which can cause ecological imbalance by killing forests and disrupting the marine life. As for the saying ‘prevention is better than cure’ goes, nuclear technology definitely fits all the requirements in providing for a safe and reliable mean for power generation as compared to coal and natural gas.

Nuclear energy produces a small amount of waste. As the quantity of waste generated by nuclear power plant is very small, the disposal of radio-active waste can be easily contained so they can be buried deep underground. Also, more effective ways can be found out as the technology is improving at a very fast pace. Avant-garde technology is constantly being developed to shield, curb, contain and disband radio-active waste.  Moreover, the quality of radio-active waste improved if it goes for reprocessing of spent fuel and the reuse of plutonium is incorporated.
