The paper explores mechanical, physical, chemical and structural properties of cement compounds based on blastfurnace slag produced in metal containers using the hot isostatic pressing (HIP) method. The study allowed to evaluate the radiation resistance of cement compounds under the influence of ionizing radiation up to an absorbed dose of 109 Gy and 1019 alpha-dispersion/g. The tests confirmed that the matrices complied with the established regulatory requirements. It was demonstrated that cement compound synthesis based on the HIP method provided matrices with enhanced physical and chemical characteristics. It was also shown that under radiation exposure, cement compounds containing high-level waste simulators retained their properties and structure.

The article describes the purification method for filtrate generated from the treatment of process uranium-containing solutions that resulted from production activities at JSC “PA ECP”. The paper presents the stages of the testing performed at a laboratory stand that enabled to identify an optimal concept flowchart for filtrate treatment.

The paper focuses on a method used to process the water from the treatment of uranium-contaminated soil resulting from the operation of JSC "AECC" sublimation facilities by hydroseparation, in particular, on its development and testing results. During the tests, the feasibility of recycled water treatment was demonstrated both suggesting the use of membrane and ion exchange methods with process parameters of the treatment stages identified. The study shows the possibility of producing uranium-containing materials in the form of ammonium polyuranates as secondary products of recycled water processing. A schematic diagram of recycled water purification following hydroseparation treatment of soil excluding the generation of radioactive waste was developed based on the results of the research.
