Technical condition assessment of a small-sized nuclear power plant after transportation unit overturning

The article considers the final stage of emergency development associated with the transport unit overturning with a small-sized nuclear power plant. Mathematical modelling allowed to obtain information about possible consequences. Among the most serious foreseeable damages are violations of the thermal protection coating in the area of the tip and bottom of the unit, which is a part of the separating head unit. To assess the unacceptability of this or that damage, the method of calculation of aerodynamic characteristics of flows near the surface with a defect was used. In case of insignificant damage, it is possible to consider further use of the unit for its intended purpose, which may be important in the threatened period for states with a limited number of such products.
