The purpose of the work is to develop the scientific and technical foundations of modern diagnostic systems for fuel assemblies (FA) and reactor internals (RI) during new types of nuclear fuel implementation in reactor facilities (RF) with VVER at NPPs of Ukraine during the over-design terms of their operation. The research method is the determination of the safety parameters of nuclear installations based on the application of modern calculation codes for modeling neutron-physical, thermo-hydraulic and vibrational processes in nuclear installations. The results of the research - the results of research on the determination of neutron-physical, thermo-hydraulic, vibrational parameters of the VVER-10000 are presented. Recommendations for the use of work results - the results of the work of the research are planned for implementation: in the development of the application software of the VVER-1000 In-core Noise Diagnostic System of VVER-1000 as part of the development of algorithms and programs for determining the vibration state of in-core devices and FA, as well as the development of diagnostic scenarios; in the development of the application software of the VVER-1000 In-core monitoring system (IMS-M2) as part of the development of algorithms and programs for determining the parameters of the burnout of the SPD emitters, determining the transition function between the SPD current and the energy release in FA.
