Theory of the swelling of porous materials

  • Published:
The Soviet Journal of Atomic Energy Aims and scope

Abstract

Equations describing the kinetics of the swelling of fissionable materials are derived for a model presupposing the existence of pores in the fissionable material. The operating conditions preceding the beginning of swelling are considered in greater detail. The concept of the time when swelling begins is introduced. Expressions which relate the time of initial swelling to the diffusion coefficient of gaseous fragments, the material's strength characteristics, the temperature, the size and concentration of pores, and the rate at which gaseous fragments are generated are derived for a number of cases.
