In January 2023 Italy registered National Assistance Capabilities to the IAEA Response and Assistance Network, RANET. These capabilities are provided by ENEA and offered to requesting Member States.

The tests at all power level were carried out successfully and the complete functionality of the 3rd unit and the achievement of the project parameters was confirmed by a 144-hour trial run at full power, which will finalize the energy start-up stage.

Severe accident code, AZORES, is coupled with plant dynamics code for SFRs, ADYTUM. Accident progression between coupled and single AZORES simulations differs significantly.

Lithuanian Nuclear Energy Association in co-operation with the Lithuanian Academy of Sciences and Lithuanian Energy Institute organized the international conference "New Trends of Nuclear Reactors: Small Modular Reactors. Experience of Leading Countries and Developers” with participation of representatives from 5 ETSON organisations (LEI, JSI, VTT, ENEA, EK-CER).

Joint ICTP-IAEA INPRO School aims to provide knowledge and basic practical experience by training on INPRO concept of nuclear energy sustainability, INPRO tools and methods on assessment and analysis of nuclear energy systems. Last Joint ICTP-IAEA INPRO School was held in 12-16 June 2023, at the ICTP’s headquarters, Trieste (Italy).

A system analysis code AMAGI (Advanced Multi-fluid Analysis code for Generation of thermal-hydraulic Information) has been developed as a best estimate code from its basic design. In the calculations using AMAGI on the void fraction experiments, technical knowledge was obtained on the differences between the AMAGI and TRACE models for each phenomenon and their impacts on the results.

The Lithuanian Energy Institute contributes to the numerical analysis of activation and fission products in irradiated cladding material of the PWR spent fuel assembly.

NRA has conducted a joint research program with the University of Tokyo to clarify how the pore sizes affect the adsorption reactions of different ions.

In 2022/23 an extensive refurbishment of the permanent exhibition on nuclear technology at the Nuclear training centre ICJT, JSI, took place: a new graphical design, a significantly larger number of interactive exhibits, a new lecture room for demonstration of radioactivity experiments.

The activities of the HARMONISE project (Towards harmonisation in licensing of future nuclear power technologies in Europe) aim to pave the way towards harmonisation of approaches to effective licensing of innovative fissions and fusion power plants. 

Europe abandons russian nuclear fuel and chooses an alternative such as Westinghouse fuel. This is testified by numerous statements of key persons from European countries and the recently launched APIS Project: Accelerated Programme for Implementation of Secure VVER Fuel Supply.

The second edition of the ETSON Conference entitled “TSO challenges in a rapidly evolving environment” will take place in Brussels on 11 & 12 October 2023.
 

The aim of the project is to develop risk analysis and forecasting system aimed at protecting ICs and national strategic assets, especially as regards the prediction of seismic phenomena. It is believed that analysis of high-resolution time series of Radon concentrations in groundwater, air and soil may be a suitable method for identifying seismic precursors. The aim of the work is to devolp new sensor technologies to create a system for forecasting, simulating and mitigating risk related to the monitoring of air, water and soil matrix.

The simulation model of the Bohunice full-scope simulator was modified to include the MELCOR severe accident code.

In the context of international organizations such as the International Atomic Energy Agency (IAEA) and the Nuclear Energy Agency (NEA) of the Organization for Economic Cooperation and Development (OECD), three international benchmarks focused on the neutronics and thermal-hydraulics of lead-cooled fast reactors (LFR) have been recently launched under the coordination of ENEA.
