“…Industries producing radioactive waste include nuclear power, nuclear medicine, nuclear research, coal and rare-earth mining, manufacturing, construction, and nuclear weapons reprocessing (Zhang, Gu, & Liu, 2019). Radioactive waste poses significant threat to human environmental health; thus, it must be managed properly to ensure that radioactive exposure does not exceed standards and regulations (Poškas, Kilda, Šimonis, Jouhara, & Poškas, 2019).…”

The reviewed papers presented here provide a general overview of worldwide radioactive waste-related studies conducted in 2019. The current review includes studies related to safety assessments, decommission and decontamination of nuclear facilities, fusion facilities, and transportation. Further, the review highlights radioactive wastewater decontamination, management solutions for the final disposal of low-and highlevel radioactive wastes (LLRW and HLRW), interim storage and final disposal options for spent fuel (SF), and tritiated wastes, with a focus on environmental impacts due to the mobility of radionuclides in the ecosystem, water and soil along with other research progress made in the management of radioactive waste. © 2020 Water Environment Federation • Practitioner points • The release of radionuclides and their subsequent fate and transport in the environment poses public health concern and has stimulated recent research on the waste management techniques. • Seeking a safe and environmental-friendly solution is the current trend for existing and projected inventories of radioactive waste. • Significant progress in the field of geological disposal of radioactive waste has been made in the last two decades.

“…The underground silo disposal method uses a silo built into a rock cavern within the bedrock or under the ground at 80-130m below sea level and is designated for low and intermediate-level radioactive waste [11]. The near-surface disposal, for disposing of the very low-level radioactive waste, is a method using a natural or artificial barrier at a depth of about 30 m sub-surface and is covered with soil after being filled [12]. In this study, applying the additional process to remove the contaminants using dry ice, the clearance criteria could be attained for the aggregates separated.…”

This study explains how to reduce the volume of radioactive wastes on the wires generated during the decommissioning process of nuclear facilities. The method involves spraying pressure treatment process to separate the aggregates from the wire; the latter of which contain the majority of the radioactive contaminants. The process acted to weaken the chemical bond between the wire and aggregate components on the wire. Optimal treatment conditions were determined to be as follows: pre-treatment for 1sec using round nozzle followed by flat nozzle horizontal to the wire for 1.5sec at room temperature. Such conditions were found to be effective at reducing the volume of the waste but could not remove the contaminants from the aggregates completely. Applying the additional process to remove the contaminants using dry ice, the clearance criteria could be attained for the aggregates separated. Therefore, the radioactive waste could be treated for clearance by the sequential treatment process, thus achieving an approximately 85% volume reduction of the radioactive waste and ultimately lowering the cost of decommissioning and waste disposal.

“…It must be noted that the Čerkezovac site has all the attributes of the appropriate location for the long-term storage and is the likely location for the disposal of the LILW, being part of the Trgovska gora, which has already been approved as a potential location for the disposal of the LILW (Schaller & Lokner, 1998). Even if the disposal is to be considered, the choice of disposal system must be properly selected and approved, according to the best practices (Dermol & Kontić, 2011;Poškas, Kilda, Šimonis, Jouhara, & Poškas, 2019).…”

Radioactive waste disposal and management presents a unique problem at the Krško nuclear power plant as it is built and co-owned by the Republic of Croatia and the Republic of Slovenia. Each country is responsible for the management of half of the low-and intermediate-level radioactive waste (LILW) and spent nuclear fuel (SNF). So far, Slovenia has officially selected the site for LILW disposal and the Croatian programme has a single location left (since 1999), not officially approved as acceptable. This paper contains a new approach to site selection related to the implementation of GIS technology and presents a map of potential areas for LILW disposal including only the remaining Croatian location. It was constructed based on eleven layers that include natural characteristics and anthropogenic pressures. For the construction of the main map, detailed topological checks and spatial analysis of polygons have been made, reducing potential areas to be further evaluated.
