Dynamic thermal stresses in reactor shells

A method of determination of the temperature and thermal stress distributions in a plane reactor shell is derived. The transient operation of the reactor is considered. It is assumed that the material of the shell is homogeneous and isotropic and satisfies the Boltzmann principle of superposition. As an example of application of the derived method two problems: elastic shell and viscoelastic shell, are solved for the case of reactor shutdown. The effects of inertia forces are taken into account.
