An overview of the prospects for the development of nuclear technologies and the conclusion of the relevant requirements for advanced structural materials, their classification and features were described. In order to obtain a bar with a modified radiation-resistant outer layer, an experiment on radial-shear rolling of the Zr-1% Nb alloy in conditions favorable for the UFG structure formation was conducted. In the process of radial-shear rolling of round bars along the route 37 mm → 20 mm in diameters with a total deformation of  ≈ 70 %, a microstructure of submicron size was obtained. The nature of the microstructure is equiaxed with mainly high-angle boundaries and large crystallographic misorientation of the grains that is the most promising from the point of view of radiation resistance.

The halogen bonds (XB) formed by the two isomers 4-methyl pyridine (MePy) and aniline (ANL) with heptafluoro-1-propyl iodide (n-C3F7I) and heptafluoro-2-propyl iodide (iso-C3F7I) were investigated using vibrational (FT-IR and Raman)...
