Abstract

Abstract: Decommissioning of nuclear facilities incurs high costs regarding the accurate characterisation and correct disposal of the decommissioned materials. Therefore, there is a need for the implementation of new and traceable measurement technologies to select the appropriate release or disposal route of radioactive wastes. This paper addresses some of the innovative outcomes of the project "Metrology for Decommissioning Nuclear Facilities" related to mapping of contamination inside nuclear facilities, waste clearance measurement, Raman distributed temperature sensing for long term repository integrity monitoring and validation of radiochemical procedures. Highlights: A novel method to rapid dissolve graphite samples was developed. Spectral characteristics of air radioluminescence for remote mapping of alpha radiation were investigated and method for mapping of contamination depth distribution was tested on a real case. New concept of waste segregation and free release measurement systems was tested. Metrological performances of distributed temperature sensing systems were evaluated. Testing on complex matrices could be achieved by combining a series of well-characterised blank matrices with liquid standard solutions.
