Abstract. Nuclear energy is the most important branch of global energy. The cost of electricity generated at nuclear power plants, as well as the absence of emissions of aerosols and greenhouse gases into the atmosphere are among the key factors that make it possible to talk about serious competition with other types of power plants. Safety issues related to radiation exposure are solved using biological protection in the form of a thick-walled reinforced concrete shell, the wall thickness of which reaches 3-3.5 m. The article is devoted to the creation of an analytical approximate calculation of a thick-walled spherical shell with a single reinforcement. Earlier, the effectiveness of using spherical thick-walled shells as polar-symmetric shells was discovered. The calculation method is based on some proposals in relation to cylindrical reactors. The essence of these proposals is to use the equations of elasticity theory to describe compressed areas, while in the stretched area only the reinforcement layer is taken into account, which is also considered elastic and homogeneous. For the polar-symmetric shell, the solution is given for the first time.
