Low-activity streams

Each method has its merits and drawbacks. For example, separation technologies remove some of the high-activity products from the streams and convert them into low-activity streams that are easier to stabilize, but generate separated components with high activity that also require stabilization. This two-phase approach adds to the total cost and may turn out to be very expensive. 

Membrane processes have been introduced on pilot plant scale in the reprocessing plant of the Bhabha Atomic Research Centre (BARC) to treat various low-active streams. The following case studies are discussed in brief. 

The basis for the IAEA draft guidance on unconditional clearance levels is the rq)orts of 14 separate national and international studies which had been directed towards the low activity streams of material generally considered to be the most likely candidates for clearance. These are ...
