The placement of Class 1 radioactive waste in crystalline rocks in carbon steel containers surrounded by a bentonite buffer is considered as one of the possible concepts in the design of the Russian deep disposal site for radioactive waste (PGZRO). Several fundamental issues of this concept are considered - determination of the minimum thickness of a carbon steel container according to the criteria of mechanical strength, taking into account the effect of a bentonite buffer and corrosion. Preliminary computational estimates of the thickness of the bentonite buffer were carried out according to the criterion of the minimum required swelling pressure.
