This tool was developed for NRG Petten. It is used in fundamental nuclear research into fuel irradiation for molten salt reactors. The samples are irradiated in HFR Petten and are kept in SALIENT-01, hermetically closed sample compartment. The puncture tool is used in an experiment to extract samples from SALIENT-01 in the right way.
The chambers in SALIENT-01 are under high vacuum, which must be retained during the drilling. In addition, there is a release of radioactivity and fluorine gases. The puncture tool must be resistant to this. This tool is connected to an external measuring installation where the samples taken are further examined.
