To ensure the structural integrity of components which are on use in nuclear installations, it is necessary to know their resistance to the initiation and propagation of cracks. Because of their dimensions it is a quite demanding task to prepare the standard fracture mechanics specimens for a classical ASTM test. All the above-mentioned led to the need of introducing a new method for assessing the fracture material properties of tubes with thin walls, called Pin-Loading Test (PLT).

In the framework of the Euratom Research and Training Programme, HARMONISE (a project expected to start in mid-2022) will study relevant research and cooperation activities in standardization and nuclear safety considering also the lessons learnt from the stress tests performed in the EU. The project is coordinated by LEI and involves nine ETSON members along with partners representing research organisations, regulators and industry.

Graphite used in nuclear plants must be disposed of properly. Prolonged aging, even at room temperature, can lead to the formation of different species, such as graphite oxide, which has the possibility of being dispersed into the environment much more easily and this entails a risk that must be taken into consideration

Clearance measurement should be performed as a conformity assessment of the evaluated contamination values to the regulatory limit, considering the measurement’s uncertainty, including the uncertainty of the ratio of the activity concentration of the difficult to measure nuclide to that of the key nuclide. The key issues for the treatment of these uncertainty were summarized.

Safety Analyses of SMR with Passive Mitigation strategies - Severe Accident (SASPAM-SA) project proposal has been submitted and has been founded in HORIZON-EURATOM-2021-NRT-01-01, “Safety of operating nuclear power plants and research reactors”. The project is coordinated by ENEA (Italy) and its key objective  is to investigate the applicability and transfer of the operating large-LWR reactor knowledge and know-how to the near-term deployment of iPWR, in the view of severe accident  and emergency planning zone  European licensing analyses needs.
