Special Issue Information

Dear Colleagues,

The effective management of nuclear waste is crucial to ensure the safe sustainable usage of nuclear energy in electricity generation, and numerous applications in medicine, industry, agriculture, and scientific research. Nuclear waste generated in these technologies must be treated and conditioned for safe handling, transportation, storage, and ultimate disposal. Nuclear waste should be disposed of aiming for the permanent protection of dangerous radioactive materials from humans and the biosphere. Both processing and disposal activities of the waste encompass the utilisation of advanced technologies and materials aiming to ensure the reliability of the waste’s long-term isolation. Cements, geopolymers, glasses, glass composite materials, ceramics, and metals are the materials analysed for expected performance in the envisaged disposal environment. Natural analogue systems and materials proven for their long-term stability and durability are investigated to ensure confidence in the multi-scale approaches currently used to predict the behaviour of waste disposal systems on geological timescales.  

This Special Issue will analyse nuclear waste management systems and activities being practiced aiming to provide a sustainable utilisation of nuclear energy. It will focus on the assessment of technological aspects of processing and disposal systems, materials performance in the storage facilities and disposal environment, and analysis of natural analogues to provide environmentally safe and sustainable employment and development of nuclear applications.

Papers selected for this Special Issue will be subject to a rigorous peer-review procedure with the aim of their rapid and wide dissemination.

The Influence of Liquid Low-Radioactive Waste Repositories on the Mineral Composition of Surrounding Soils

Clay minerals may transform in various systems under the influence of geological, biological, or technogenic processes. The most active to the geological environment are technogenic and biochemical processes that, in a relatively short time, can cause transformation of the rocks’ composition and structure and formation of new minerals, especially clay minerals. Isolation of radioactive waste is a complex technological problem. This work considers the influence of alkaline solutions involved in the radioactive waste (RW) disposal process. In the Russian Federation, due to historical reasons, radioactive waste has accumulated in various types of repositories and temporary storages. All these facilities are included in the federal decommissioning program. Solid radioactive wastes in cement slurries at the landfill site of the Angara Electrolysis Chemical Combine are buried in sandstones and currently suffer the influence of a highly alkaline and highly saline groundwater storage area, which leads to a considerable transformation of the sandstones. This influence results in the formation of peculiar "technogenic” illites that have smectite morphology but illite structure which was confirmed by modeling of X-ray diffraction (XRD) patterns. The described transformations will lead to the increase of porosity and permeability of the sandstones. The research results can be used in assessing the potential contamination of the areas adjacent to the disposal site and in planning the decommissioning measures of this facility. Full article

Calculation of Potential Radiation Doses Associated with Predisposal Management of Dismantled Steam Generators from Nuclear Power Plants

Although the generation of large components from nuclear power plants is expected to gradually increase in the future, comprehensive studies on the radiological risks of the predisposal management of large components have been rarely reported in open literature. With a view to generalizing the assessment framework for the radiological risks of the processing and transport of a representative large component—a steam generator—12 scenarios were modeled in this study based on past experiences and practices. In addition, the general pathway dose factors normalized to the unit activity concentration of radionuclides for processing and transportation were derived. Using the general pathway dose factors, as derived using the approach established in this study, a specific assessment was conducted for steam generators from a pressurized water reactor (PWR) or a pressurized heavy water reactor (PHWR) in Korea. In order to demonstrate the applicability of the developed approach, radiation doses reported from actual experiences and studies are compared to the calculated values in this study. The applicability of special arrangement transportation of steam generators assumed in this study is evaluated in accordance with international guidance. The generalized approach to assessing the radiation doses can be used to support optimizing the predisposal management of large components in terms of radiological risk. Full article

Structural properties and water dissolution of six sodium–aluminum–phosphate (NAP) glasses have been investigated before and after irradiation by a gamma-ray source based on 60Co. Two of these samples were of simple composition, and four samples had a complex composition with radionuclide simulants representing actinides, fission, and activated corrosion products. Samples of the simple composition are fully vitreous, whereas samples of the complex composition contained up to 10 vol.% of aluminum–phosphate, AlPO4, and traces of ruthenium dioxide, RuO2. Based on the study of pristine and irradiated glasses, it was established that the radiation dose of 62 million Gray had practically no effect on the phase composition and structure of samples. At the same time, the rate of leaching of elements from the irradiated samples by water was decreased by about two times. Full article
