The National Center for Nuclear Research (NCBJ) is developing the groundbreaking HTGR-POLA high-temperature research reactor project. The work has the potential to revolutionize the energy industry in Poland and become a model for the development of nuclear technology in Europe.  

The purpose of the HTGR reactor 

HTGR-POLA (High-Temperature Gas-cooled Reactor) is a high-temperature, helium-cooled reactor. It is designed to produce heat at temperatures as high as 950°C, enabling applications in a wide range of industries such as chemistry, petrochemistry and hydrogen production. Its innovative nature is based on its ability to produce electricity and heat simultaneously (polygeneration), which can fill the energy and process steam needs of local communities and industries.  

Milestones in project’s development 

NCBJ began researching the HTGR concept more than a decade ago, preparing the basic design of the project under the HTR-PL initiative in 2012-2015. The current goal of the research team is to develop detailed technical documentation that will be used to obtain a license from the National Atomic Energy Agency. This process includes, among other things, material testing, laboratory upgrades and international cooperation with the Japan Atomic Energy Agency (JAEA).  

Advantages and safety of the technology 

HTGR reactors have a high level of safety due to the use of TRISO, an innovative fuel in the form of microspheres coated with a protective layer that minimizes the risk of releasing decay products. Closed-cycle gas cooling systems ensure operational stability and efficiency even in the event of sudden changes in energy demand.  

Future prospects 

The current phase of the project is scheduled for completion in the fall of 2024. Prototype reactors with a thermal capacity of 40 MW are expected to be developed into larger units in the following years. Anticipated applications range from local industry to large-scale power plants. With the support of the government and international partners, HTGR-POLA has the potential to become a model for the innovative energy industry of the future, supporting global decarbonization goals.  

The HTGR-POLA project is an example of an ambitious approach to the development of nuclear technologies that can significantly impact energy security and the modernization of Polish industry.
