Free release measurement facilities

Status: in operation

Two free-release measurement facilities are installed in Ignalina NPP (159B and B10 buildings), where intended devices measure whether materials and wastes correspond to the clearance condition by determining the concentration of radionuclides.

Depending on the results it is decided, whether materials and waste no longer needs to be controlled from the point of view of radiation protection. These materials can be reused or waste can be treated as ordinary waste. For example, part of the equipment or metal parts can be reused in industry or construction rubble can be treated as ordinary construction waste.

Other waste that exceeds out-of-control levels are decontaminated again, or managed as radioactive waste.
