A model taking account of the contribution of the filler, binder, and ensemble of microcracks in the characteristics of reactor graphite is proposed. An analytical solution of this model is obtained. The solution is used as a basis for calculating the elastic moduli and sound speed in graphite. It is shown that the anisotropy of the computed sound speed and its dependence on the hydrostatic pressure are in agreement with experiment.
