The actual priority of National Radiation Protection Institute (SURO) is to support State Office for Nuclear Safety (SUJB) in the licensing process for the APR-1000 unit from Korean supplier KHNP. SURO experts are currently analyzing the initial information (Plant Design Description, Standard Safety Analysis Report, Concept of Safety Report).

In 2025 SURO is still participating in European Commission and national projects in areas of nuclear safety. The consortium represented by SURO and UJV Rez, a.s. have started project Strengthening of TSO capabilities in the use of the ASTEC code for the needs of the Czech regulatory body – SUJB. The main goal of the project is strengthening the capabilities of SUJB in DEC-B safety assessment of the current fleet of Czech NPPs, as well as for new builds, including SMRs. The project enables a streamlined exchange of the knowledge base and best practices in severe accident modelling between SURO and UJV Rez, a.s., using the ASTEC code. An added value of the project is provided by decreasing the dependency of computional codes developed outside EU.

The project coordinated by ENCO Consulting Ges. M. B. H - Further strengthening the nuclear safety and radioprotection regulator in Türkiye is progressing broadly as expected. Other members of the consortium are SURO, Slovenian Nuclear Safety Administration, Nuclear Regulatory Authority of the Slovak Republic, and Hungarian Atomic Energy Authority. Experts from SURO and SUJB are involved in all areas of project, with the largest contribution in the areas of decommissioning of research reactors and radiation facilities and for near surface radioactive waste disposal, operational experience feedback, inspections, and regulatory control for the commissioning and early operation of NPPs.

During of October, 2025, the ETSON JSP Workshop took place in Trnava, Slovakia, organized this year by VUJE, a.s. our two succesfull junior staff had opportunity to present
their work with the title “PWR fuel rod Sensitivity Analysis with TRANSURANUS for the LOC-HBu benchmark” and in frame of topic Safety analysis methodologies and nuclear research the Python automation for subchannel analysis has been presented.

In December 2025, SURO joined a consortium, that is supposed to provide a joint early review (JER) of the LDR-50 SMR. This reactor has been designed by Steady Energy and there has been already provided a safety assessment by STUK.
