Diagnostics of the IBR-2 research reactor's movable reflector state based on the analysis of radioactive impurities in oil

摘要

The report describes the algorithm for diagnosing the technical state of the movable reflector (MR) in the IBR-2 research reactor, which is based on analyzing radioactive impurities in oil. The impurity analysis results were used to establish the onset and development time of the structural component degradation processes. The quantitative content of radioactive isotopes in oil was used to assess the wear rate for the movable reflector's mechanical parts.
