Disposal of radioactive waste materials and spent fuel is a major and important technology. How the waste radioactive material is disposed off ?
Ans. Nonusable fission products are radioactive and take short/medium/long time for radioactive decay to reach safe level of radioactivity. Accordingly three methods of disposal are :
(a) Zero or low radioactivity material is dispersed or stored without elaborate shielding.
(b) Medium radioactivity material is stored for short duration of about 5 years to allow decay of radioactivity.
(c) High radioactive material. They are stored in water for several months to permit radioactive decay to an accepetable low level.
