VUJE implemented several changes to the thermohydraulic model, delivered code for severe accident and two new 3rd party systems. 
The aim of the ongoing project is to make the FSS more representative and in line with the real control room.

Sacca di Goro, in the Adriatic Sea (north of Italy), is one of the areas affected by widespread radioisotope contamination after the Chernobyl accident. A campaign was recently conducted in its lagoon to verify the current status of some radionuclides such as 137Cs, 40K, 238U, 232Th and 226Ra in sediments. 

Various gases are produced by metal corrosion and organic material degradation in deep gelological repository for nuclear waste. To ensure repository safety, it's important to demonstrate that gases can be dissipated by diffusion in host rocks and prevent pressure buildup in repository near field. Smectite mineral particles form a pore network that is usually saturated with water, making gas diffusion the primary transport mechanism. 

The plans for a new NPP in Slovakia are manged by the company JESS. The first milestone for reaching this aim is to obtain a siting permit for this new NPP.

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.
