Deep Isolation asks states to include waste disposal in their nuclear strategy
Nuclear waste disposal technology company Deep Isolation is asking that the National Association of State Energy Officials (NASEO) consider how spent nuclear fuel and radioactive waste will be managed under its strategy for developing advanced nuclear power projects in participating states.

Using experimental data from indicator pump tests, various theoretical migration models for radionuclides in groundwater-bearing horizons were considered. The model parameters necessary for these considerations, especially migration velocity and dis-persivity, were obtained by statistical analysis of experimental data. These results show that pulse-like indicator injection best measured values for the model of instantaneous injection in indicator-free flowing groundwater in an infinite strata.
