News from ETSON and its members*
24 Oct 2023 | Vuje | | Successful completion of SAT tests for the Bohunice FSS project VUJE implemented several changes to the thermohydraulic model, delivered code for severe accident and two new 3rd party systems. |
24 Oct 2023 | ENEA | | Evaluation of the radionuclide concentration in the sediments of the Sacca di Goro (Italy) 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. |
24 Oct 2023 | PSI | | Mobility of Dissolved Gases in Smectite under Saturated Conditions 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. |
24 Oct 2023 | Vuje | | Licensing documentation for a siting permit for a new Slovak NPP 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. |
24 Oct 2023 | ENEA | ENEA’s Role in the Italian Participation to IAEA’s RANET 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. |
24 Oct 2023 | Vuje | | Mochovce NPP Unit 3 Commissioning 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. |
31 Aug 2023 | NRA | | Preliminary Analysis Focusing on In-Vessel Thermal Hydraulics in Loss-of-Heat Removal Systems in a Sodium-Cooled Fast Reactor Severe accident code, AZORES, is coupled with plant dynamics code for SFRs, ADYTUM. Accident progression between coupled and single AZORES simulations differs significantly. |
31 Aug 2023 | LEI | | International conference "New Trends of Nuclear Reactors: Small Modular Reactors. Experience of Leading Countries and Developers” 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). |
31 Aug 2023 | RATEN ICN | | Training Young Professionals on Nuclear Energy Sustainability 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). |
31 Aug 2023 | NRA | | Development of a system analysis code AMAGI 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. |
31 Aug 2023 | LEI | | LEI involvement in the EURAD work package on Spent Fuel Characterisation The Lithuanian Energy Institute contributes to the numerical analysis of activation and fission products in irradiated cladding material of the PWR spent fuel assembly. |
31 Aug 2023 | NRA | | Pore size effects on adsorption of metal ions 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. |
05 Jul 2023 | JSI | | New exhibition on nuclear technology at the Nuclear training centre ICJT 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. |
05 Jul 2023 | JSI | | Workshop on the Safety of Small Modular, Advanced and Fusion Reactors, June 20-21, Celje, Slovenia 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. |
05 Jul 2023 | SSTC NRS | | Europe Preparing to Abandon Russian Nuclear Fuel 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. |
