Singapore is exploring the possibility of adopting nuclear power, particularly small modular reactors (SMRs), as part of its long-term energy strategy. With advancements in safety features and reduced land requirements, SMRs have gained interest across Southeast Asia, including in Malaysia, Vietnam, and Thailand. Floating SMRs, in particular, offer potential benefits but also pose unique challenges that must be carefully evaluated.
Growing Global Interest in SMRs
Several countries are investing in SMRs for energy security and sustainability. Indonesia is considering a floating SMR near Bangka Island, while Russia has operated a commercial floating nuclear power plant, the Akademik Lomonosov, in Arctic waters since 2020. China has also developed land-based SMRs, with its first unit operational in Shandong province and another planned in Hainan by 2026.
Tech companies are also looking to secure nuclear energy for data centers. Google recently signed a deal to purchase electricity from multiple SMRs, and Oracle is designing a data center powered by three SMRs. Industries with high energy demands, such as mining and chemicals, are also exploring SMRs as a viable energy solution.
Why Floating SMRs Could Work for Singapore
Given Singapore’s limited land area and tropical climate, floating SMRs present an attractive option. Unlike land-based plants, which require significant space and cooling infrastructure, floating SMRs can be deployed along coastlines and utilize seawater for cooling, increasing efficiency.
Floating SMRs can be constructed in shipyards, towed to their destinations, and installed with minimal landscaping. This reduces construction time and allows for easier maintenance, refueling, and eventual decommissioning. Additionally, they can be used for cogeneration, supplying both electricity and industrial steam to facilities like those on Jurong Island. They could also support seawater desalination, enhancing Singapore’s water security.
Challenges and Risks of Floating SMRs
Despite their advantages, floating SMRs come with challenges. Operating in a marine environment increases costs due to wave motion wear, corrosion, and the need for specialized filtration systems to prevent marine organism buildup. The Akademik Lomonosov, for example, saw its budget quadruple due to these factors.
Another concern is safety. Although nuclear energy has strict regulatory oversight, public concerns over radioactive waste storage, potential accidents, and environmental impact remain significant. International monitoring agencies would play a key role in ensuring transparency and safety compliance.
Site Selection and Economic Feasibility
Choosing the right location is critical. Deeper waters provide better cooling and lower environmental impact, but certain locations may pose risks. For example, deploying an SMR near Changi could raise concerns due to its proximity to the airport, while placing it near industrial hubs like Jurong Island could improve economic feasibility.
Economic studies must assess whether floating SMRs can provide cost-competitive energy compared to other renewable sources, such as solar and hydrogen. While initial investments are high, long-term benefits, including energy security and carbon reduction, may justify the costs.
A Strategic Energy Decision for Singapore
If Singapore moves forward with nuclear energy, floating SMRs deserve serious consideration. They offer flexibility in deployment, reduced land constraints, and potential integration with industrial processes. However, comprehensive studies on affordability, safety, regulatory requirements, and environmental impact must guide decision-making to ensure alignment with Singapore’s long-term energy goals.
