Question

Write about the various disposal methods used for disposing solid, liquid and gaseous waste from power plants?

Answer 1

Gaseous wastes are made to discharge in the atmosphere through high stacks. Moderate liquid wastes, after a preliminary treatment is discharged into the deep pits.  Active liquids are stored within the concrete tanks. These tanks are buried under the ground till the percentage of radioactivity decays up to a level which is safe for disposal. Solid wastes are classified into combustible wastes and non-combustible wastes. Combustible wastes can be reduced to ashes by putting them into fire where as non-combustible  wastes consists of concrete, glass, metal, asbestos and various other things which cannot be converted to ashes by burning. Land burial is the best method employed for such type of wastes.
