ORAL Track 4. Fast Reactor Materials (Coolants, Structures) and Components 4.2 Structural, Novel, and Large Components Materials


Alexander Orlov


The future of nuclear power lies in inherently safe fast reactors operating in a closed nuclear fuel cycle. The concept of inherent safety, which is based on deterministic exclusion of the most serious accidents due to the internal properties of the reactor, and not by creation of engineering barriers, is the foundation for ensuring the safety and economic efficiency of future nuclear power. “Proryv” is the leading Russian nuclear power project, which develops technologies of a fast lead-cooled reactor BREST-OD-300 and a closed nuclear fuel cycle based on the principle of inherent safety. The key element of ensuring the safety of the BREST-OD-300 fast reactor is the lead coolant.
Liquid lead was chosen as the main coolant for the nuclear power plant with inherent safety because of its physicochemical properties, which provide certain advantages over other types of coolants considered for inherently safe reactors, but its use also carries some technological challenges in the process of reactor operation.
The system for monitoring and maintaining the quality of the heavy coolant of BREST-OD-300 reactor consists of a set of high-tech devices designed to operate and maintain the key properties of the coolant over decades of operation. The development of these systems required an innovative approach, as well as many years of work to justify them.
The report presents the advantages of the lead coolant, its technology, the impact on safety and the current state of development for the following components of the system for monitoring and maintaining the quality of the lead coolant for the BREST-OD-300 reactor: oxygen activity sensor, mass exchange devices, hydrogen purification system, coolant filter, hydrogen sensors.
