Aim:  To install, test and calibrate on a decommissioning site a facility for pre-selection and free release measurement of wastes from nuclear facilities. The facility will have scintillating detectors for pre-selection of wastes and germanium detectors for free release measurement. The facility will be surrounded by low activity concrete shielding to meet the limits given by national nuclear regulators for unconditional release of wastes from nuclear facilities in the environment.

Mechanical and detection parts (a conveyor, four HPGe detectors with mechanical cooling and four plastic scintillators) for the waste pre-selection and the free release measurement facility were installed at NUVIA site (CZ) for testing and optimisation. Next, this equipment will be transported to CIEMAT (ES) and the facility including low-activity concrete shielding will be built on CIEMAT’s decommissioning site
