Information × Registration Number 0123U100144, ( 0223U001352  ) R & D request Title Choice of thermogasdynamic models and possible scenarios for release of radioactive aerosols into the NSC volume, the annular space of the NSC Arch and into the environment as a result of a fire on the turbine hall roof Head Krukovskyi Pavlo H., Доктор технічних наук Registration Date 09-01-2023 Organization Institute of Engineering Thermophysics of NAS of Ukraine popup.description1 The aim of the work is to simulate the spread of radioactive aerosols in the main volume of the NSC, the annular space of the NSC Arch and releases into the environment in 2 types of RA rise scenarios - RA release during the collapse of the structure and the rise of the RA, which is located in the roof of the fire. The calculated changes in the level of RA concentration in the OO and the integral release of RA outside the NSC (not more than 700 Mbq) for the accepted time of the scenarios (18 hours) are the final results of modeling for the selection of compensatory measures for the protection of personnel and the environment. popup.nrat_date 2024-12-09 Close
