Introduction

The decommissioning of nuclear installations generates large amounts of several types of material streams. Depending on their radionuclide composition and activity concentrations, some of the materials can be recycled in the conventional industry or in the nuclear industry, while other material streams will be considered as radioactive waste to be disposed of in specific designed final repositories. During the decommissioning of Belgian Reactor 3 (BR3), a huge amount of radiological data is being produced and managed with the main goal to fulfil the acceptance criteria for the targeted destinations. On the other hand, the immense data availability could represent a valuable source for data mining. Unfortunately, the available data is not always sufficiently organised for direct use.

Objective

In a first phase, the trainee will follow/perform measurement campaigns and the data interpretation process under supervision, to learn more about data quality and the full radiological data acquiring processes related to waste characterisation (e.g. use of HPGe detectors) and the building release process (use of HPGe detectors and hand held equipment for total alpha, total beta and total gamma radiation). In a second phase, the trainee will analyse the currently applied data acquiring processes and adjust those processes allowing future data mining.  The final objective will be to initiate the first data analysis processes.
