In continuation of the NEA-guided experimental programmes at the PKL test facility in Germany operated by Framatome GmbH, the fourth phase of the NEA PKL project was conducted between June 2016 and September 2020. The topics of the experimental investigation had been defined in collaboration with the project partners and were considered of high interest. On certain topics, the PKL experiments were complemented by experiments at the PWR PACTEL test facility (operated by Lappeenranta-Lahti University of Technology, LUT, Finland) and the PMK-2 test facility (operated by Centre for Energy Research, Hungarian Academy of Sciences, Hungary). The report provides an introduction to the test topics, the key safety objectives addressed and the conclusions drawn from the results.
