3. INTRODUCTION
• Any activity related to the Radioactive fuel cycle,
produce radioactive waste.
• Radioactive waste generated during various
operations of the nuclear fuel cycle such as Mining,
nuclear power generation etc.
• Various processes in Industry, defence ,nuclear
weapons reprocessing, medicines and scientific
research produce byproducts that includes Radioactive
waste.

7. CLASSIFICATION OF NUCLEAR WASTE
ON BASIS OF RADIOACTIVITY
VOLUME OF WASTE
7 3
• Radioactive waste can be in
gas, liquid or solid form, and its
level of radioactivity can vary.
• Depending on the level and
nature of radioactivity,
radioactiv wastes can be
classified as
• Low Level Waste
• Intermediate level waste
• High Level Waste.
LOW LEVEL
INTERMEDI

8. As a waste management
philosophy, utmost
emphasis
is given to waste
minimization
at all stages of design,
operation and maintenance.
For effective confinement,
volume reduction is a key
factor in the choice of
technologies for use in
radioactive waste
management plants.

9. TECHNOLOGY OF VITRIFICATION IN INDIA
• Immobilization of high level liquid waste into vitrified
borosilicate glasses.
• engineered interim storage of the vitrified waste for passive
cooling and surveillance over a period of time qualifying it for
ultimate disposal.
• Ultimate storage disposal of vitrified waste a deep
geological depository.
• The following technique are used for vitrification
•Pot melter used at Trombay
•Joule Heated Ceramic Melter (JHCM)
at Tarapur

CONCLUSION
• Disposal of radioactive waste is a complex issue not only
because of nature of the waste but Also the regulatory dealing with
radioactive.
• Radioactive waste disposal politics have changed substantially
over the last twenty years.
• An going effort to upgrade technology to minimize radioactive
discharge is also on.
