Radioactive waste management and the law / Az Azimah Abd Aziz and Siti Aminah Ali
Published 2008“…This project paper studies the law on radioactive waste management in Malaysia. Since there is no specific law on radioactive waste management, the focus of this research is on Atomic Energy Licensing Act 1984 (Act 304) because it contained provision on Atomic Energy including radioactive material and radioactive waste. …”

Mixed finite element approximation of porous media flows
Published 2023“…The reliable simulation of flow in fractured porous media is a key aspect in the decision making process of stakeholders within politics and the geosciences, for example when assessing the suitability of burial sites for storage of high–level radioactive waste. This thesis aims to tackle the challenge that is the accurate simulation of these flows and does so via three computational developments. …”

Efficient cesium encapsulation from contaminated water by cellulosic biomass based activated wood charcoal
Published 2021“…Most importantly, about 98% of volume reduction was obtained by burning (500 °C) the Cs adsorbed charcoal, which ensured safe storage and disposal of radioactive waste. Therefore, this study can offer a guideline to produce a functional adsorbent for effective Cs removal and safe radioactive waste disposal.…”

The Role of Mass Spectrometry to study the Oklo-Bangome Natural Reactors
Published 2007“…The Oklo–Bangombé natural reactors are therefore geological analogs that can be evaluated in terms of possible radioactive waste containment sites. As more reactor zones were discovered, it was realized that they could be classified into two groups according to their burial depth in the Oklo mine-site. …”
