A study by a Swedish nuclear-waste consultancy found no major technical roadblocks preventing Singapore from storing nuclear waste underground [1].
The findings suggest that the city-state could potentially serve as a regional hub for nuclear-waste disposal. This possibility comes as nations seek long-term solutions for the hazardous byproducts of nuclear energy, which require secure, isolated storage for thousands of years.
The research, which was released in 2024 [1], took the form of a desktop study conducted in partnership with Singaporean authorities [1]. The consultants evaluated the geological and technical requirements for creating a deep underground repository on Singaporean soil [2].
While the initial assessment is positive, the report indicates that the findings are based on existing data. The consultancy said that further site surveys and detailed geological investigations are required to confirm the safety and stability of specific locations [1].
Singapore has not historically operated nuclear power plants, but the study explores the technical feasibility of managing such materials [2]. The potential for underground storage depends on the ability to isolate waste from the biosphere—a challenge that requires specific rock formations and stable groundwater conditions.
The collaboration between the Swedish firm and Singapore authorities aimed to determine if the region's geography could support such an infrastructure [1]. By identifying the absence of major technical barriers, the study provides a baseline for future policy decisions regarding hazardous waste management in Southeast Asia [2].
“No major technical roadblocks prevent Singapore from storing nuclear waste underground.”
This study marks a shift from theoretical discussion to technical assessment regarding Singapore's role in the nuclear fuel cycle. While the lack of technical roadblocks is a significant first step, the transition from a desktop study to a physical repository involves immense regulatory, political, and public safety hurdles. Establishing a regional waste hub would position Singapore as a critical infrastructure provider for neighboring countries adopting nuclear energy, though it would also introduce long-term environmental liabilities.
