26 Sep 2022 Raman spectroscopy as a powerful tool for characterization of graphite used in nuclear plants Newspicture Raman spectroscopy as a powerful tool for characterization of graphite used in nuclear plants

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

Application of statistical non-parametric methods to radioxenon distributions in atmosphere in order to study the atmospheric background fluctuations and the influence of anthropogenic activities.

26 Sep 2022 Safety Analysis of SMR with PAssive Mitigation strategies - Severe Accident (SASPAM-SA) Horizon Euratom Project Newspicture Safety Analysis of SMR with PAssive Mitigation strategies - Severe Accident (SASPAM-SA) Horizon Euratom Project

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.

22 Feb 2022 A surrogate model for atmospheric dispersion newspicture A surrogate model for atmospheric dispersion in emergency situations leveraging ensemble weather forecasts

Ensemble weather forecasts can be very useful in properly predicting the dispersion of radioactive material in an accident, but they are very expensive to use. We present a surrogate model approach that aims at recovering the information from the whole ensemble while trying to still be fast enough to be used in emergency situations.

Analyzing the concentrations of tritium in groundwater it is possible to trace the age of the aquifer and / or define if the aquifer is polluted by anthropogenic activities

30 Aug 2021 Noble gas sampling in air and subsurface using ultra low background high purity germanium newspicture Noble gas sampling in air and subsurface using ultra low background high purity germanium

Instead of automated sampling for noble gases and analysing stations, manual system can be used to better accommodate costs for the equipment and flexibility of usage. One of this system has been developed by the Traceability Laboratory at the ENEA Research center of Brasimone, which was specially designed in order to keep the sampling equipment separate from the processing and measurement.

15 Mar 2021 New element and speciation specific analytical options at PSI hot laboratory newspicture Preparing software tools for the ALFRED reactor licensing: the ANTEO+ subchannel code example

In light of the licensing of the ALFRED demonstrator by the Romanian regulator CNCAN, ENEA, as member of the FALCON Consortium, is prepapring the relevant software tools for their qualification. A rigourous approach, based on the guidelines and best practices in place in the European context, has been followed and applied to the validation case of the subchannel code ANTEO+, used in the thermal-hydraulics analyses of the fuel assemblies
