Write two disadvantages of nuclear energy?
Answers
1) radioactive waste :
radioactive waste is any material, whether solid, liquid or gas that consists of a radioactive nuclear substance and the operators of the nuclear plant have determined that it’s a waste. radioactive material is considered waste after it has spent more than 3 years in the reactor producing heat and electricity. This waste comes from nuclear reactors and needs to be disposed of or stored safely and conveniently considering they are highly dangerous and can let off radiations if disposed of incorrectly.
The reason it has to be disposed of safely and appropriately is that it is able to emit radiations even after thousands of years. The storage or disposal of radioactive waste is the main reason slowing down expansion of nuclear energy. Handling and safe storage can happen as long as it’s cooled and workers insulated from the radiation it emits by thick material such as steel, concrete or a few meters of water.
2) environmental impact :
though the nuclear energy contributes less in the accumulation of greenhouse gasses, its catastrophic effect because of its spent fuel produces radiation to people and environment that lasts for a long duration of time or even lasting. On the other hand, on animals and humans, radiation could kill cells and mutate the DNA. the Chernobyl accident affect the animals by the immediate death of the rodents. On humans, radiation causes radiation sickness and cancer that is commonly a thyroid cancer.
