The requirement to maintain pre-determined oxygen potential in order to prevent corrosion and erosion of structural steels is one of features concerning use of heavy liquid metal coolants (HLMC). In the article presented are the up-to-date methods and devices for automatic monitoring and control of oxygen content in HLMC assuring conditions for prevention of structural steels corrosion in the course of the long-term operation. Tests of the prototype automatic systems of monitoring and control of oxygen content in HLMC carried out in the experimental facilities confirmed the reliable maintaining of assigned oxygen mode and high potential of this area of development. By now, SSC RF – IPPE has gained the unique knowledge and experience in creating systems capable of assuring pre-determined oxygen mode in HLMC, this being the basis for the development of the similar systems for the new generation fast reactors.
