The nuclear stopping power of hydrogen isotopes and helium in Be, C, W materials, which are promising for use as the first wall of a tokamak-reactor, are calculated. It is shown that the presence of an attractive well in the potential significantly affects the dependence of nuclear stopping power on the collision energy. The use of potentials calculated in the density functional theory with an attractive well allowed us to obtain more accurate values of the nuclear stopping power for hydrogen isotopes, which at low energies differ by 27-60% from the reference data. The results for different hydrogen isotopes are well described by a universal curve.
