Material Irradiation Research and Services

Part of materials research are also proposals, operations and evaluations of the experiments. For this reason we perform:

  • radiation experiments focused on materials behaviour research, chemical parameters and radiation influence
    • proposal and realization of experimental programs in different environments (water, supercritical water, steam, helium, liquid metals, molten salts) and various conditions (high temperature and pressure, radiation, cyclic stress of samples) with the aim of materials corrosion behaviour study, IASCC, crude deposits, corrosion products transport, etc.,
    • proposal and realization of experimental facilities (loops, canals, probes, autoclaves, sample holders, instrumentation, etc.) including preparation of their technical documentation and production,
    • actual implementation of the experiments in corresponding experimental facilities of the research reactor LVR-15 including continuous monitoring of experimental conditions (thermal-hydraulic, chemical, radiational and non-radiational) and subsequent evaluation of exposed samples state,

 

  • corrosion behaviour evaluation of the construction materials placed in steam-water circuits and liquid metals
    • local and global damage mechanism and nature of corrosion attack in operating conditions evaluation,
    • mechanism of corrosion damage in model operating conditions determination according to the level of mechanical stress and aqueous environment composition,

 

  • corrosion behaviour evaluation of the fuel coverage material and crud formation, after-radiation controls are included (visual inspection, oxide layers measurement using eddy currents, thickness and composition of crud measurement),

 

non-destructive inspection of complete fuel assemblies’ construction condition, including complete geometry of the fuel assemblies’ measurement (for more information see  Inspection of nuclear fuel)
