Is nuclear power green?

Points For[edit]

Nuclear power is the only viable substitute for coal[edit]

Wind and solar power are other green energy solutions but because they are unpredictable and unreliable nuclear power is the only viable substitie for coal. Nuclear power can satisfy high energy demand based on the facilities built rather than depending on unpredictable natural factors.

[1]

Nuclear power can keep up with population growth with breeder reactors[edit]

Reactors that make more radioactive fuel create an unlimited supply of energy [2]

Nuclear Power, the clear choice![edit]

Not only is Nuclear energy much safer in terms of lives lost in manufacturing, but compared to coal and electricity its carbon foot print is non-existent. Also, the process of generating nuclear power creates very little waste or by-products[3].

CANDU(Canadian Deuterium Uranium)power plants use cleaner methods to produce energy such as wind, solar, hydro, and biomass which makes them a reliable source of power. Research has also shown that CANDU Nuclear Plants can supply electricity with zero emissions of greenhouse gases. There are studies also stating that these nuclear power plants produce small emissions compared to other power plants. The study also reviews the life cycle of several different types of Power Plants. [4].

Many people believe that by 2050, greenhouse gas emissions will increase, along with oil demand. To reduce CO2 emissions, nuclear energy plays a very crucial role in doing so[5].

Clean Energy? Think nuclear power[edit]

The world is heavily dependent on fossil fuels that have been proven to be detrimental to the environment. Nuclear power plants produce energy from nuclear fission and are the most clean and environment friendly source of energy among other forms of power sources including coal, oil, gas and hydro power [6].

No harmful emissions[edit]

Compared to other major existing energy sources such as coal and oil, nuclear power emits almost no greenhouse gases or nitrogen oxide and sulfur dioxide, which are the primary components of air pollution[7]

Points Against[edit]

Mining Uranium is Harmful to the Environment[edit]

The mining of uranium around the world for nuclear energy purposes is not as regulated nor as guarded as it is recommended to be. Studies suggest that improper procedures of uranium extraction have caused excessive radiation levels and pose a direct threat to its immediate environment. For a change to occur, there must be a global consensus on how to extract uranium in the safest, most environmentally conscious way. [8]

Leukaemia Rates Higher in Children Close to Nuclear Power Plants[edit]

Children under the age of 5 that are within a 5km area around nuclear power plants in Germany had higher rates of leukaemia than those in a control group. [9]

NO Radiation is Okay Raditation[edit]

The opinions of doctors regarding the nuclear power industry are not well known because they receive little to no attention from congress on the issue. Helen Caldicott focuses on dangers that we are not aware of nor do we see yet from the impacts of nuclear radation. Many physicists advocate for nuclear power because they focus on the external less harmful sources of radatation. Physicists also do not acknowledge that radiation is cummulative and the harmful effects may not surface until later in life or generations later. There are many long term effects that will take generations to appear from incidents such as Chernobyl or Fukushima [10].

There is no safe method for Disposal of nuclear waste[edit]

Isolation is the safest method for disposing of nuclear waste, and there are many environmental implications associated with this disposal method. [11]

Nuclear Power Would Not Stop Climate Change[edit]

Problems that arise when planning to build a new nuclear plant are analyzed.

[12].

Increase in cancer post Three Mile Island disaster[edit]

Residents living near the Three Mile Island nuclear plant were evaluated to see if there was an increase within cancer rates. This took place after the disaster in 1979 where the nuclear plant overheated resulting in a nuclear meltdown. [13]
