Numerical simulation of the dielectric permeability, electric fields and mechanical strains in the fuel containing masses (FCM) is carried out. Method of the determination of water content in the FCM by measuring the dielectric permeability is suggested. Analysis of 1) - processes leading to the appearance of electric fields; 2) - defect formation due to the irradiation by the incorporated radionuclides; 3) - mechanical strains emerging due to the different thermal expansion coefficient of the constituent components of the FCM is fulfilled. Estimates show that the third process may significantly influence degradation of the FCM.
