摘要：

We determine possible causes of premature failures of typical reinforcing ropes of the protective shells of nuclear power plants with regard for the mechanical parameters of wires, the character of damages to their surfaces, and the fractal dimensions of the fracture surfaces. It is shown that brittle fracture is realized for lower levels of plasticity of the metal of wires and lower degrees of its damage. This type of fracture is characterized by a higher fractal dimension of the fracture surfaces.
