Problem to solve
Oxygen concentration monitoring and control is an important issue in the development of GEN IV lead-cooled nuclear reactors. It is possible to conduct tests on significant-sized oxygen sensors (scaled systems) and carry out experimental campaigns to increase data and knowledge on the behavior of oxygen in liquid lead (diffusion, mass transfer, chemical interactions) for the control of the concentration in lead.
Description
The system consists of a steel vessel containing 150 liters of molten lead (pure). It is equipped with an injection gas control system (cover gas and bubbling) based on the Ar-H2-O2 system and it has a mixer to mix the lead. From the cover flange, it is possible to insert thermocouples and oxygen sensors into the molten lead volume, as well as a specimen holder to perform exposure tests of materials under mixed lead conditions.
Innovative aspects and advantages
- The mixer, installed on the cover flange, allows for experimental campaigns to assess the effect of mixing on the behavior of oxygen in the lead (diffusion, mass transfer, other chemical reactions)
Admissible applications
- Exposure of materials in mixed molten lead (pure)
- Functionality tests and calibration of oxygen sensors for molten lead (pure)
- Oxygen concentration control tests in molten lead (pure)
