Investigation methods Experimental investigations: temperature, moisture in «NSC-SO» complex; dynamics of volumetric activity, dispersity and radionuclide content of radioactive aerosols, dynamics of flux density of «unorganized» release, radionuclide deposition density, dynamics of RCW clusters behaviour and their volumetric activities, radionuclide content in RCW, neutron flux density and temperature in area of localization of potentially nuclear hazardous FCM cluster, laboratory research of samples, process, interpretation and submission of obtained information. Results and their novelty As result of realized work, new data were gathered, which characterize the state of «NSC-SO» complex. Implementation rate Obtained information can be used to substantiate further investigations and recommends on monitoring of state of radiation and nuclear safety of SO and preparation of correction actions to support needed level of SO safety. Area of results application. The works are destined to estimate current state and to forecast FCM state over the time as based on the interpretation and generalization of the obtained data, which are output data for development of scientific report on the topic Significance of work and conclusions. The importance of work is due to the changes in conditions and FCM degradation with time being inside the SO, which can significantly worsen the state of nuclear and radiation safety, at the same time, information obtained within RDW framework will allow conducting correction actions, if needed.
