Disposal of Wastes from Operating NPPs

Wastes generated from nuclear facilities are in the form of gaseous, liquid and solid. The public dose limit
of 1mSv is apportioned among the various facilities located at a given site in a conservative manner. This
apportioned dose is further subdivided among atmospheric, aquatic and terrestrial pathways and also among
radionuclides which are specific to the installation.

Solid wastes generated from nuclear power plants are generally low level waste which are
decontaminated, compacted and disposed of in engineered near surface disposal facilities

Disposal of Disused Radioactive Sources

Spent radioactive sources from radiation facilities must be safely disposed of once they reach the end of
their useful life. These sources are disposed of at authorised waste management facility in the country. In
India two sites are authorised, one is at Bhabha Atomic Research Centre (BARC), Mumbai and another is
at Central Waste Management Facility (CWMF), Kalpakkam. The imported sources are sent to the original
supplier abroad.

During the year, 63 approvals were issued for disposal of radioactive sources at authorized waste management
facilities within the country and 348 approvals for exporting back to supplier in the country of origin
