Czechia

Main platform for national support of technology research and development in the Czech Republic is Technology Agency of the Czech Republic (TACR). It is an organizational unit of the state that was founded in 2009 by the Act No. 130/2002 Coll. on the support of research, experimental development and innovation. The creation of TA CR is one of the cornerstones of the fundamental reforms in research and development (R&D) in the Czech Republic. The key features of the reform is the redistribution of financial support from the national budget. The Technology Agency of the Czech Republic simplifies the state support of applied research and experimental development which has been fragmented and implemented by many bodies before the reform. In the past 10 years, UJV Rez and CVR submitted a number of project proposals to various calls of TACR, resulting in more than 10 projects actually supported by the organization, 8 of them being currently ongoing. The ongoing projects are listed in the following table.

2018
Ends in 2025
ALLEGRO
Design and testing of key systems and components for ALLEGRO.
2018
Ends in 2024
MKN

Development of a new class of Zr based alloys and high entropy alloys with optimized properties for Nuclear industry.

2018
Ends in 2022
NOVA
Development of sacrificial materials for core catchers of GFRs
2018
Ends in 2024
REDEAL
Testing of construction materials in gaseous environments at extreme conditions (high temperature, corrosive environments).
2019
Ends in 2025
SODOMAHe
Stability and resistance of materials for high-temperature helium-cooled reactors.
2020
Ends in 2023
KOBRA
Development of a passive safety systems for GFRs/VHTRs based on prolongation of primary compressor rundown by utilization of decay heat.
2020
Ends in 2023
PMATF
Methods for the characterization, testing, and qualification of irradiated samples of ATF materials.
2020
Ends in 2024
MATPRO
Development of “better concrete” based on inorganic polymers for extreme conditions.

As can be seen from the timeline above , majority of the ongoing projects is focused on material development, since it was identified as the most pressing area. Safety research and development of systems and components closely follows.

Another notable achievement is successful full commissioning of an electrical heated 1 MW mock-up of GFR called S-ALLEGRO in 2020. This facility plays a key role in thermal-hydraulics and safety research of GFRs, and will be a vital part of higher-TRL development and testing of systems and components in the near future.

Hungary

In Hungary, a major national project on GFR was finished in 2018. With the recent reform of the Hungarian Academy of Sciences, and individual entity “Center for Energy research” (EK) was formed, and development of the ALLEGRO reactor is one of its research priorities. Since 2019, EK, alongside with several universities and private companies, are the leading entities in GFR research in Hungary, with focus on reactor physics and nuclear fuel, safety, and thermal-hydraulics.

Poland

In Poland, there is currently no ongoing national project focused primarily on the GFR technology. However, Polish HTR program is very broad, with several substantial R&D projects ongoing, and with a plan for a fast deployment of an HTR prototype designed in Poland. Since there is a high number of cross-cutting R&D issues between the HTR and the GFR technologies, experience and results obtained from these projects are valuable contributions for development of ALLEGRO.

Slovakia

In Slovakia, a major national project on ALLEGRO development finished in 2015, focused on building of competences and development of the concept. One of the major achievements of the Slovakian GFR program is the successful commissioning and operation of the STU helium loop – an experimental facility aimed at study of natural convection in helium-cooled reactors. First experimental results were already obtained and published.
