FINAL DEEP RW DISPOSAL FACILITY: PETROGRAPHY OF THE SITE

JOURNAL: 2024, ¹ 3 (28), p. 59-75

AUTHORS: K.V. Martynov, A.N. Nekrasov

ANNOTATION:

Scanning electron microscopy with electron probe microanalysis has been used to study the main rock varieties of the Yeniseisky site (Krasnoyarsk Territory), where construction of an underground research laboratory has begun, as the first stage of the construction of a deep geological repository for radioactive waste. The petrographic typology of the studied rock samples is justified by their textural and structural characteristics, the main parageneses and the composition of rock-forming minerals, which are determined by the genesis of rocks. The results obtained can be used to substantiate the safety of the radioactive waste disposal facility to clarify the geological and structural models of the rock mass and the physicochemical conditions for the spread of radiation pollution as a result of the mobilization and transfer of radionuclides with pore-fractured groundwater.

Keywords: radioactive waste, deep disposal, Nizhnekansk massif, gneiss, dolerite, amphibolite, lamprophyre, metamorphism, metasomatism, cataclase, hypergenesis, mylonite.
