Singapore Pursues Nuclear Energy Research Amid Public Concerns

Singapore is actively enhancing its workforce and ramping up research efforts as it examines the potential for nuclear energy to power the nation in the future. While an official timeline for implementation remains unspecified, authorities acknowledge that rigorous safety standards and public confidence will be critical challenges.

Chia Meng Hwee, deputy director of the Energy Market Authority’s (EMA) Nuclear Energy Office, emphasized the emotional nature of nuclear energy discussions. “We have to take into consideration the public’s understanding and the confidence in the technologies that will be deployed,” he stated. He noted that successful regional deployment could boost public confidence in nuclear technologies, while any setbacks could negatively impact perceptions.

Nuclear Energy: A Controversial Solution

Currently, approximately 95 percent of Singapore’s electricity is generated from natural gas. This heavy reliance renders the country vulnerable to fluctuations in global prices and supply chain disruptions. With rising energy demands and increasing climate pressures, the push for cleaner and more reliable alternatives has intensified. Experts point out that conventional energy solutions often do not align with Singapore’s unique constraints, advocating for smaller and more innovative approaches.

To explore these possibilities, the EMA has engaged Mott MacDonald, a consultancy firm, to study nuclear energy technologies. Recent advancements, particularly in compact reactors, have made nuclear energy a more viable option for land-scarce Singapore. Small modular reactors (SMRs) represent a next-generation technology that promises to be simpler, faster, and potentially more cost-effective to construct than traditional large-scale reactors. Conventional reactors typically require extensive land and can take nearly a decade to complete.

SMRs, by contrast, require less land and can be easily scaled. They utilize prefabricated modules that are shipped and assembled on-site, significantly reducing construction time and costs. With a generating capacity of around 300 megawatts per unit—about a third that of traditional reactors—SMRs are already operational in countries like Russia and China, with projects progressing in the United States, Canada, and the United Kingdom.

Prioritizing Safety and Regional Cooperation

Safety concerns are paramount in discussions about nuclear energy. SMRs employ passive safety systems that can shut down and cool the reactor without the need for pumps or human intervention. “For us, safety is absolutely non-negotiable,” stated Dr Ming Tan, global nuclear practice lead at Mott MacDonald. He emphasized the importance of focusing on safety and design advancements in SMRs to translate these technological innovations into a robust, evidence-based understanding for Singapore.

To bolster public safety, Singapore has implemented a national radiation monitoring program that tests air, land, and water samples across the island. A network of monitoring stations continuously checks for anomalies, enabling rapid detection of potential nuclear radiation. Soil and water samples are also assessed for radioactivity levels that could pose health risks.

The radiation monitoring program serves not only Singapore but also enhances detection capabilities in the region, especially as countries like the Philippines and Indonesia prepare for nuclear power plant operations. Mr Ang Kok Kiat, group director for radiation protection and nuclear science at the National Environment Agency, highlighted the importance of fostering nuclear safety cooperation among regulatory counterparts in Southeast Asia. This initiative builds upon collaborative efforts within the Association of Southeast Asian Nations (ASEAN), which has already yielded tangible outcomes, including regional early warning systems.

The Singapore Nuclear Research and Safety Institute aims to consolidate expertise in nuclear technology and safety while developing a skilled workforce to support nuclear initiatives. Its director, Associate Professor Chung Keng Yeow, indicated that the country should be ready to adopt new reactor technologies once they have undergone sufficient testing. He noted ongoing efforts to build human expertise in this area through scholarships and training programs.

As Singapore navigates these complex challenges, the balance between energy needs, safety, and public perception remains a critical focal point in its exploration of nuclear energy’s potential role in the nation’s future.
