The first generation of nuclear power plants and reprocessing facilities is coming to the end of their working lives. The aim of the decommissioning process is to clear the site, while minimising the risk to the public and the environment from the hazardous waste arising. Two of essential steps in decommissioning process are pre-selection of wastes either to repository, or potential free release to the environment, and free release measurement. These needs are supported by the EU Council Directive 2011/70/EURATOM, where necessity of the development of new measurement techniques is stated to improve safe and effective management of radioactive wastes.
The overall aim of JRP 16ENV09 'MetroDecom II – In-situ metrology for decommissioning nuclear facilities' was to provide the metrology for decommissioning nuclear facilities. The project addressed the needs to achieve traceability to primary standards of activity of radionuclides and to validate the calculation methods used for activity determination of radionuclides occurring in wastes either stored in radioactive waste repositories or free released to the environment.
Within the JRP 16ENV09 project, pre-selection and free release measurement facility was constructed, and operational, measurement, calibration and evaluation software prepared.
In accordance with the EMPIR 2020 SIP Call scope a new project 20SIP02 has been proposed that takes into consideration the needs related to outputs of the MetroDecom II. It provides results which enable 1) transferring the new technology and knowledge to a commercial business and 2) bringing the developed facility to wide international market and adoption by wide community of end-users. The results of the 20SIP02 project are:
• Report on the modification of pre-selection and free release measurement facility for different types of nuclear facilities, and national and European legislations.
• Detail description of pre-selection and free release measurement facility for each interested end-user, identified during the project, taken into account the required throughput, types of wastes, radionuclides of interest, pre-selection and free release criteria, and legislative requirements.
