The objectives of the research programme are to ensure that the authorities have sufficient expertise available in different situations, to develop nuclear safety competences and to perform high-quality scientific research.

The full-scale invasion of the russian federation troops into the territory of Ukraine caused many political, economic, social troubles and problems. In addition to the destroyed infrastructure and huge mined areas, Ukraine also faced a radiation threat. In addition to the more than 1 year ZNPP occupation, the territory of the exclusion zone and the zone of unconditional (obligatory) resettlement was captured for a month, looted and mutilated.

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.

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.

During the internship the phenomena of High Burnup Structure (HBS) formation was investigated. Working with locally developed mechanistic fission product release code called MFPR-F researcher participated in the code coupling effort, where MFPR code was integrated into TRANSURANUS fuel performance code.
