|22 Feb 2023 | ETSON||Statement of the ETSON Board on the renewed interest and initiatives in nuclear energy
In view of the renewed interest and initiatives in nuclear energy in numerous countries in Europe and around the world, the members of the European Technical Safety Organisations Network (ETSON) – a grouping of 17 EU TSOs and their associated members in Japan, Ukraine, and the United Kingdom – have started a network-wide reflection on its future strategy.

The current energy debate could do with more facts and less gut feeling – argue Thomas J. Schmidt, renewables expert and head of the PSI Energy and Environment Research Division, and Andreas Pautz, nuclear energy specialist and head of the PSI Nuclear Energy and Safety Research Division. In this joint interview, they set out the challenges that science needs to address in connection with the Swiss government’s Energy Strategy 2050 and why nuclear energy and renewables experts must work closely together.

In order to establish the Nuclear Safety Requirements Document (NSRD) for the post-operational phase (POP) of the Belgian NPPs, the licensee (Electrabel) applied an efficient Integrated Safety Approach (ISA) based on Bel V recommandations.
|28 Dec 2022 | PSI |||Award winning work on high-resolution X-ray radiography methods for boiling experiments at high pressure
Light Water Reactors (LWRs) such as the ones operating in Switzerland work at relatively high temperatures and pressures. As a consequence, thermal-hydraulics experiments investigating relevant LWRs phenomena at prototypical conditions require test sections with relatively thick steel walls. This poses significant challenges for the implementation of suitable instrumentation to capture phenomena of interest, such as the flow regimes during transition from liquid to steam. The characterization of flow regimes in the presence of boiling is rather complex, and their better understanding would allow to develop mathematical modeling tools that can be used to optimize equipment and better assess safety margins. To perform in-situ measurements of the boiling process under high-pressure conditions, the team of authors from PSI, ETH, and the University of Michigan has developed a new high-fidelity and high-speed imaging system based on x-ray radiography, which provides high-resolution details on the boiling process while being non-intrusive. Since the instrumentation is located outside of the test section, it has also the advantage that can be easily moved to take measurements in different region of the test sections.

VUJE has delivered a manipulator for remote controlled plugging of VVER-1000 steam generator heat exchanging tubes for Zaporizhzhia Nuclear Power Plant. Following South Ukraine NPP, Khmelnitsky NPP and Rivne NPP , Zaporizhzhia is the fourth nuclear power plant in Ukraine which will be using this unique device manufactured by VUJE, a.s.
|28 Dec 2022 | PSI |||Synthesis of Metallic Lanthanide Thin Samples
This work aimed to produce intermetallic samples of platinoid metals (active metal matrix) and lanthanides (co-metal) and via the method of Coupled Reduction, i.e. a thermal treatment of the combination of the lanthanide oxide and noble metal at high temperature, as high as 1100 °C, under a constant flow of H2. We have demonstrated by means of several techniques, such as Scanning Electron Microscope, Energy Dispersive X-Ray Spectroscopy, Alpha Spectrometry and Radiographic Imaging, that this method, at defined experimental conditions (temperature, pressure and concentration) yields a metallic lanthanide thin film when using platinum as active metal matrix. Conversely, the formation of a bulk intermetallic compound was obtained when using Pd as matrix. Those systems will have applications in different nuclear physic and radiochemistry studies, such as irradiation targets for production of superheavy elements and for nuclear data determination.

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.

This highlight presents a successful, in-house developed integration of an Electron Beam Ion Source (EBIS) able to ionize gases to high charge states with a customized commercial MC-ICP-MS. The successful joining of the two ion flight paths is a milestone towards comprehensive routine analyses of solids, liquids, and gases using THE SAME MASS SPECTROMETER, the latter analyses free from atmospheric contamination. After implementation of an introduction system for gas mass spectrometry, routine analyses will comprise isotope ratio and relative abundance determinations of fission gases in used nuclear fuel. In addition to the unique versatility of the MC-EBIS-ICP-MS, inclusion of the EBIS further opens the little-studied field of mass spectrometry of highly charged ions.
