GENERAL KNOWLEDGE

Detailed explanation-1: -Radioactive wastes are stored so as to avoid any chance of radiation exposure to people, or any pollution. The radioactivity of the wastes decays with time, providing a strong incentive to store high-level waste for about 50 years before disposal.

Detailed explanation-2: -Like all radioactive material, radioactive wastes will naturally decay over time. Once the radioactive material has decayed sufficiently, the waste is no longer hazardous. However, the time it will take for the radioactive material to decay will range from a few hours to hundreds of thousands of years.

Detailed explanation-3: -A proposed system for storing nuclear wastes involves storing the radioactive material in caves or deep mine shafts. One of the most toxic nuclides that must be disposed of is plutonium-239, which is produced in breeder reactors and has a half-life of 24, 100 years.

Detailed explanation-4: -And just like any fuel, it gets used up eventually. Your 12-foot-long fuel rod full of those uranium pellet, lasts about six years in a reactor, until the fission process uses that uranium fuel up.

Detailed explanation-5: -Two common treatment techniques are: incineration of solid waste and evaporation of liquid waste. The third step in the process – conditioning – brings the waste into a safe, stable and manageable form so it can be transported, stored and disposed.
