Summary: The migration and transformation of trace nuclides during the pyrolysis and gasification of low-level radioactive waste were evaluated. The addition of ZrO2 reduced the migration of cesium in plastic and glove. Phosphorus and sulphur resisted the migration of cobalt. Controlling the pyrolysis and gasification temperature can prevent the migration of cesium, cobalt, and strontium.

Summary: In this study, Nd-doped zirconia ceramics were successfully prepared using the hydrothermal assisted sol-gel method. With the increase in Nd content, the phase structure of ZrO2 changed and the grain size and compactness of the obtained ceramics increased with the increment in sintering temperature. The successful accommodation of Nd within the ZrO2 lattice was confirmed by the detected increase of cell parameters. This study provides a new method for the immobilization of high-level radioactive waste.

Summary: In this study, a series of tungsten-based composites were synthesized through One-Pot Hydrothermal Route to act as effective protective barriers against gamma rays. Various experimental methods were used to determine the composites' viability as radiation shields, and the ternary composite Pb0.82Bi0.12WO4/W0.5Pb0.5Bi12O20 was found to be the most efficient radiation shield. The results were confirmed through MCNP-5 Monte Carlo simulation code and XCOM theoretical calculations data, showing a strong relationship between the synthesized composites' chemical composition and their shielding capacity.

Summary: The present work aims to optimize the radiation protection efficiency for ion-selective containers used in the liquid treatment for the nuclear power plant cooling cycle. The study found that using natural rocks as filler materials and increasing the filler thickness can reduce the absorbed dose and equivalent dose received from the radioactive waste container. Additionally, the type of filler material significantly affects the equivalent dose rate.

Summary: In this study, a polymer/zeolite-based composite barrier material was prepared and its performance against 126Sn isotope in a radioactive waste repository was investigated. The adsorption behavior of tin ions on the barrier material was analyzed using isotherms and kinetic and thermodynamic parameters. The risk of 126Sn migration and the associated health risks were assessed using Monte Carlo Simulation Software.

Summary: The comprehensive shielding behaviors of chambersite deposit in China for neutron and gamma ray were systematically analyzed for the first time. The results showed that the chambersite deposit has excellent shielding performance for high energy and low energy neutrons, and its gamma ray shielding ability is between steel-magnetite concrete and ilmenite concrete. The prepared sample of chambersite deposit has better shielding performance for both thermal neutron and gamma ray compared to other materials.

Summary: Evaluating the radiation shielding behavior of rocks is important for construction purposes. This study investigated the radiation shielding properties of Neoarchean mafic and ultramafic rocks from the Bhavani Shear Zone in southern India. The results showed that different band combinations and techniques can effectively discriminate and map the rock types and distribution. Additionally, a feasible container design for disposing of radioactive wastes was proposed using Monte Carlo simulation.

Summary: This study presents a new fast isostatic hot pressing method for fabricating W-Cu composites with nanosized grain boundaries and high effective density. The microstructure analysis shows that the samples have a polycrystalline well-packed structure, with copper acting as a matrix surrounding the tungsten grains. The W-Cu composites exhibit high shielding efficiency against gamma radiation in the 0.276-1.25 MeV energy range, making them excellent materials for radiation protection.

Summary: This study investigates the groundwater flow patterns and circulation characteristics in a deep geological repository for radioactive waste disposal at the Xinchang site in China using numerical simulation technology. The results show that most of the precipitation is discharged through evaporation, with a small portion infiltrating into shallow groundwater. The groundwater flow is closely related to topography and lithological distribution, and can be classified into three types of flow systems based on various characteristics. The study also examines the influence of bottom boundary depths on groundwater characteristics.

Summary: 60% of people believe that radioactive waste generated from NPPs is risky for the environment, while 40% think coal power plants are more hazardous than NPPs. On the other hand, 43% and 50% believe that radioactive waste disposal is an unsolved issue and high risk for the country. However, 34% and 41% of respondents partially disagreed with the regulatory authority and DoE on solving the issue.
