Disposal of nuclear waste: The waste products by nuclear fission may be solid, liquid or gas. i) Solid harmful disposals are packaged as required and shipped to a burial site for disposal. ii) Liquids are processed through filters, boiling and leaving the solid impurities. The process is carried out till the pure water is obtained from the disposal. The waste is then released to environment. iii) Gaseous wastes are filtered, compressed to take up less space and then allowed to decay for some period. After the require time has been passed, the gases are sampled and tested. If the required limits are met, these will be released to atmosphere.
