Q. Why nuclear energy is not green?
The mining, milling and enrichment of uranium into nuclear fuel are extremely energy-intensive and result in the emission of carbon dioxide into the atmosphere from the burning of fossil fuels. Thermal pollution from nuclear power plants adversely affects marine ecosystems.
Q. Is nuclear waste really a problem?
One is leftover fuels that were used in nuclear power plants to generate electricity. The other is the waste made by facilities involved in nuclear weapons production or by facilities that reprocess and recycle used power plant fuel. All these wastes can remain dangerously radioactive for many thousands of years.
Q. Can radioactive waste kill you?
Very high doses like those experienced by workers at the site of nuclear accidents (several thousand times higher than the background radiation level) cause extensive damage, resulting in a range of symptoms known collectively as radiation sickness. Extremely high doses can kill in days or weeks.
Q. Why doesn’t the US reprocess nuclear fuel?
A major obstacle to nuclear fuel recycling in the United States has been the perception that it’s not cost-effective and that it could lead to the proliferation of nuclear weapons. Those countries realized that spent nuclear fuel is a valuable asset, not simply waste requiring disposal.
Q. What is the main problem with nuclear waste?
Nuclear energy produces radioactive waste A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
Q. Which is more expensive coal or nuclear power?
Nuclear is comfortably cheaper than coal in seven of ten countries, and cheaper than gas in all but one. At 10% discount rate nuclear ranged 3-5 cents/kWh (except Japan: near 7 cents, and Netherlands), and capital becomes 70% of power cost, instead of the 50% with 5% discount rate.
Q. How safe is nuclear power?
The evidence over six decades shows that nuclear power is a safe means of generating electricity. The risk of accidents in nuclear power plants is low and declining. The consequences of an accident or terrorist attack are minimal compared with other commonly accepted risks.
Q. How long is nuclear waste radioactive?
Radioactive isotopes eventually decay, or disintegrate, to harmless materials. Some isotopes decay in hours or even minutes, but others decay very slowly. Strontium-90 and cesium-137 have half-lives of about 30 years (half the radioactivity will decay in 30 years). Plutonium-239 has a half-life of 24,000 years.
