PROCEDURE OF RW MANAGEMENT

Step 4: Conditioning of radioactive waste

Conditioning is those operations that produce a waste package suitable for handling, transporting,
storage, and/or disposal

Objective of conditioning radioactive waste is to convert the waste into a form, which is

i. Leach resistant, such that the release of radionuclides will be slower even though they are in
contact with liquid
ii. More stable mechanically, thermally, chemically, radiological, throughout handling, storage and

disposal

The operations are including

i. The conversion of the waste to a solid waste form by an addition of immobilization agent

ii. Homogeneous material with lower leaching rate than the unprocessed waste
iii. An enclosure of the waste in containers

iv. Providing an over pack
