“…With a permeability value of n. E-19 m 2 and a hydrodynamic gradient of 15 Pa m -1 the filtration rate will be only c.5 x 10-Sm/a (Petrov et al 1998). However, flow rates obtained in the area under investigationduring well logging -are considerably higher (Drozhko et al 1997). Underground flow and contaminant transport must therefore take place through structures at a scale larger than rock samples, namely fractures, faults and dislocation zones.…”

This paper is the result of laboratory tests aimed at comparative assessment of the filtration, elastic and mechanical properties of metavolcanics, as well as a preliminary investigation of the nature of characteristic variations in P-T parameters, simulating the conditions in the vicinity of an underground storage facility for heat-generating radioactive waste. The properties have been studied in cores collected from the deepest (1200 m) hole in the metavolcanics, focusing on intervals subjected to different strain intensities. Interpretation of the data obtained suggests that the identification of the most probable pathways for fluid flow and radionuclide transport depends on estimates of the retardation characteristics of zones of disjunctive dislocation. However, the widespread occurrence of linear zones of schistosity, mylonitization and brecciation may not be a decisive negative factor in the long-term performance assessment of the underground storage facility, because these minerals, which concentrate radionuclides such as epidote, chlorite, sericite, and Fe oxyhydroxides are widely distributed in these zones. Moreover, open microfractures and pores affected by heat will be filled with neoformed minerals (epidote, chlorite, carbonate) characterized by high sorption capacity with respect to radionuclides, due to release of intergranular water, as well as carbonatization reactions. Simultaneously, the system of open macro-and microfractures that resulted from stress affecting relatively undisturbed blocks may be one of the factors dramatically reducing country rock retention capability. Therefore, the results of petrophysical and mineral-chemical investigations must be taken into account in feasibility studies of designs for the construction of underground systems for final disposal of high-level wastes and/or long-term storage of spent nuclear fuel in the PA Mayak area.

“…Geological information is based upon reports by Russian workers in the area, (Drozhko, et al, 1993;Solodov, et al, 1994) and on observations by other members of the field party (Drozhko, et al, 1996). In general, the water in DH 176 is strongly contaminated, while that in DH 173 is clean.…”

“…Components of the survey were positioned to take advantage of drillhole control, while avoiding interference from cultural features such as pipelines and drill casings. Profile A runs along the longer geologic cross section of Figure 2, between drillholes 43/78 and 173, through drillhole 176, site of extensive logging and packer tests (Drozhko, et al, 1996). Profile B is situated south of the Mishelyak River, in an area thought to lie beyond the present extent of the contaminant plume.…”

Electrical resistivity and induced polarization (IP) data from the area of a radioactive and nitrate-rich groundwater plume were gathered by a joint Russian-American team. The results show the contaminated area both to be conductive and to have an anomalously low IP response. The low IP response may be due to a radiolytic reaction with the dissolved nitrate, yielding oxygen which, in turn, reacts to remove accessory pyrite from the host rocks.
