Assessing Radioactive Waste Container Performance: Structural and Non-linear Dynamic Analysis

Hyeongjin Byeon

Considering the measured compressive strength changes depending on test conditions, the effect of test conditions should be analyzed to avoid overestimation or underestimation of the compressive strength during disposal. We selected test conditions such as the height-to-diameter ratio, loading rate, and porosity as the main factors affecting the compressive strength of cement solidified radioactive waste. Owing to the large variance in measured compressive strength, the effects of the test conditions were analyzed via statistical analyses using parametric and nonparametric methods. The results showed that the test condition of the lower loading rate, with a height-to-diameter ratio of two, reflected the actual cement content well, while the porosity showed no correlation. The compressive strength assessment method that reflects the large variance of strengths was suggested.

Radioactive waste is a significant concern for the safe and responsible management of nuclear materials. Proper containment of radioactive waste is crucial to prevent the release of hazardous materials into the environment. Assessing the performance of containers used for radioactive waste is essential to ensure their structural integrity and reliability. This article explores the importance of structural and non-linear dynamic analysis in evaluating the performance of radioactive waste containers.
