We have developed a debris bed formation prediction method that takes into account accident scenarios and physical properties by providing THERMOS with the analysis results in MELCOR.
The Fukushima events have highlighted the need for improved safety approaches and numerical tools to assess hydrogen risk. In this regard and under the auspices of ETSON, two main projects are underway. The first is to organize benchmarks for hydrogen combustion codes and the second is to develop Technical Safety Assessment Guidelines (TSAG) for hydrogen risk assessment expected to be completed by the end of 2022.
SÚRO v.v.i. together with ÚJV Řež, a.s. and Centrum výzkumu Řež s.r.o. received from the Technology Agency of the Czech Republic (TAČR) the TAČR 2021 Award in the category "GOVERNANCE" for the project "Computational model for thermomechanical behaviour of a fuel rod with the inclusion of degradation processes of nuclear fuel coverage" (TRANSURANUS Project).
GRS experts develop computational code that can be used to simulate muon radiographic images in order to test the suitability of the method for examining storage casks for spent fuel assemblies.
In the framework of the EU-funded project “ENEEP – European Nuclear Experimental Educational Platform”, a demonstration course titled “Experimental Reactor Physics” was successfully carried out at the Jožef Stefan Institute for a group of 10 students in February 2022.
As part of the radiological monitoring of workers exposed to ionizing radiation, IRSN provides dosimetry services by continuing its R&D efforts to make available state-of-the-art dosimeters. This is the case for the "new generation" RPL-neutron dosimeter, which was put into service on January 1, 2022.
One of the biggest challenges for today's European research reactors is the sustainability of their operation and the related need to secure the supply of nuclear fuel. Two groups of research reactors are particularly affected by this challenge.
"The Internet is on fire" – that was the message in mid-December 2021 when a security loophole in the Java framework log4j became known, making a wide range of cyber-attacks possible. The Federal Office for Information Security then raised a "red" alert, the highest warning level. Quite a number of companies around the world have turned out to be affected. On behalf of the Federal Ministry for the Environment, GRS experts are analysing cyber-attacks and security incidents that may also be relevant for German nuclear facilities and installations in order to protect them accordingly.
The sealing of a geological repository for radioactive waste must ensure a major containment function over a very long period. To enable its experts to assess the safety files drawn up by Andra (1) as part of the CIGÉO project (2) IRSN is conducting active research on this topic, as shown by the VSEAL project, carried out in its underground research laboratory in Tournemire (Aveyron).
A team of young researchers at the National Radiation Protection Institute in Prague uses state-of-the-art tools to measure and instantly visualise current radiological and meteorological data, making the results ready for interpretation in a matter of seconds.
