| Abstract: | Mathematical models of the migration of radionuclides taking account of a phase transition of the interstitial solution in soil are proposed. The moisture-transport equation can be represented in moisture and potential forms. The results of a long-time comparative numerical experiment checking the effectiveness of the proposed models using special methods of numerical simulation are presented.Translated from Atomnaya Énergiya, Vol. 97, No. 5, pp. 374–380, November, 2004. |
