Heavy liquid metal (HLM) coolants offer new perspectives for the development of innovative nuclear systems for nuclear waste transmutation and energy production. The Belgian Nuclear Research Centre (SCK CEN) is working on the development of HLM cooled MYRRHA accelerator driven system (ADS). MYYRHA will serve as an ADS demonstrator for transmutation, as an HLM reactor pilot plant and it will be used as an irradiation tool for research. With this, it is at the forefront of HLM nuclear technology worldwide.
During this summer school, participants will gain insight into the state-of-the-art research focused to the development of MYRRHA and other HLM-based nuclear systems. The summer school will cover several aspects of HLM technology that are essential for the engineering design and safety of nuclear systems.
Experts from SCK CEN and other internationally renowned research organizations will give the lectures. They will cover the most advanced HLM-based nuclear systems and deal with the neutronics, chemical, thermal hydraulic and materials issues and challenges in instrumentation, safety and design. Complementary to the lectures, visits are foreseen to various experimental facilities that were constructed at SCK CEN in support of the MYRRHA project.
Throughout the course week, participants will have the opportunity to brainstorm on best practices and selections of technologies for HLM cooled nuclear systems in interactive sessions with the experts.
Places for this summer school are limited to 20. Participants are invited to send in an abstract for a poster presentation on their research project.
The summer school will take place in Mol, Belgium. In case COVID-19 measures at the time do not allow a face-to-face meeting, we will switch to an online format, with online alternatives for the laboratory visits.
- To set the frame, the motivation for HLM-based nuclear systems and the design of several of the most developed HLM facilities will be introduced. In addition, the link with accelerator technology for ADS systems and partitioning and transmutation fuels is made.
- In a module on chemistry you will be introduced to the various sources of impurities in HLM and to methods for their purification, to oxygen monitoring and control systems, and to the chemistry of radioactive impurities.
- In the module on materials you will learn to select materials for structural and functional components of reactors and get acquainted with irradiation damage processes and with liquid metal induced corrosion and its mitigation strategies.
- The thermal hydraulics module will start from the fundamentals of heat transfer in liquid metals to provide insight in the thermal hydraulic phenomena occurring in the fuel assembly and primary system. Experimental and numerical tools for the system safety analysis will also be covered.
- In the instrumentation module you will get an overview of measurement techniques that can be used in liquid metals and focus in more detail on ultrasonic measurements.
