AKKUYU NUCLEAR POWER PLANT COST & BENEFIT ANALYSISAğustos 30, 2017
IRAQ: GOING BACK AND FORTHAğustos 30, 2017
Nuclear power plants were born in 1950s. Taking only 30 grams of used fuel annually for a person’s energy consumption many countries built their own nuclear power plants. In this story, there is the fuel on one hand and the waste on the other. In general sense, used up fuel rods from nuclear reactors and the waste from reprocessing plants are referred to as nuclear waste. These wastes can be stored for decades in the cooling pools of nuclear reactors (world-nuclear.org). Nuclear power plants are only one source of nuclear wastes, the others are medicine, research facilities, oil and gas extraction, mining, etc. Not all of this waste is produced inside reactors, but they come from concentrated natural structures. This waste is divided into three categories, yet, the boundaries between the categories differ from country to country.
- High Level Waste (HLW): This waste is still very radioactive and continues to produce heat. Only 2% of nuclear waste falls into this category but 98% of radioactivity comes from this. They are transported by dry cast storage containers which weigh 100 tons when empty and can contain 12 tons of HLW and cost €1.5 million each. If used reactor fuel is to be reprocessed, the final liquid HLW product needs to be solidified. This product is made into a glass of borosilicate.
- Intermediate Level Waste (ILW): It usually comes from reprocessing plants, research facilities and turned-off reactors. They are transported by several cylindrical containers that are painted yellow for identification. The wastes are compressed to save from volume.
- Low Level Waste (LLW): This category is still radioactive and produces a small amount of heat but does not require cooling. The majority of all nuclear wastes are considered LLW. Like ILWs, they are transported by several cylindrical containers that are painted yellow for identification. The wastes are compressed to save from volume.
