Singapore Expands Nuclear Energy Studies to Enhance Safety and Workforce

Singapore is actively bolstering its workforce and increasing research efforts as part of its exploration into the potential of nuclear energy to power the nation in the future. Although there is no official timeline for implementation, government authorities emphasize that stringent safety standards and public confidence are crucial challenges to address as interest in nuclear energy rises across the region.

Mr. Chia Meng Hwee, deputy director of the Energy Market Authority’s (EMA) Nuclear Energy Office, stated, “Nuclear energy is an emotive subject, so we have to take into consideration the public’s understanding and the confidence in the technologies that will be deployed.” He highlighted that successful deployment of nuclear energy in the region could enhance public confidence in these technologies. Conversely, setbacks in deployment could negatively impact local and regional perceptions.

To engage the public and improve understanding of energy challenges and the facts surrounding nuclear power, the EMA has committed to ongoing dialogue and information dissemination.

Rethinking Energy Sources

Currently, approximately 95 percent of Singapore’s electricity is generated from natural gas. This heavy reliance exposes the country to fluctuations in global prices and supply chain disruptions. Observers note that as energy demand rises, alongside limited land availability and increasing climate pressures, the urgency for cleaner and more reliable energy alternatives has intensified.

Given the constraints within Singapore, traditional energy solutions may not be viable. Instead, the EMA has appointed consultancy firm Mott MacDonald to evaluate nuclear energy technologies. The advancement of compact nuclear reactors makes this energy source a more feasible option. Small modular reactors (SMRs), a next-generation technology, are designed to be simpler, faster, and potentially more cost-effective to construct than conventional reactors. Traditional reactors are large and can take nearly a decade to build, while SMRs can be operational sooner.

These smaller reactors require less land and can be manufactured in prefabricated modules, allowing for easier assembly on-site. Each SMR has a generating capacity of around 300 megawatts, which is about one-third that of conventional reactors.

Prioritizing Safety Standards

Safety remains a top priority for the Singaporean government as it explores nuclear options. SMRs incorporate passive safety systems that can autonomously shut down and cool without requiring pumps or human intervention. Dr. Ming Tan, global nuclear practice lead at Mott MacDonald, asserted, “For us, safety is absolutely non-negotiable.” He emphasized a commitment to focusing on key safety and design advancements in SMRs, which include their inherent safety features and compact designs.

Singapore’s national radiation monitoring programme plays a vital role in addressing safety concerns. It involves testing air, land, and water samples across the island. A series of monitoring stations continuously check for anomalies in the air, enabling rapid detection of any spikes that could indicate nuclear radiation. Soil and water samples are also routinely tested for radioactivity to ensure public safety.

As Singapore prepares for potential nuclear energy deployment, the benefits extend beyond its borders. The country aims to enhance detection capabilities regionally, as nations like the Philippines and Indonesia take preliminary steps toward establishing nuclear power plants. Mr. Ang Kok Kiat, group director for radiation protection and nuclear science at the National Environment Agency, stated, “We are catalyzing nuclear safety cooperation among our counterpart regulators in the region.”

This effort builds on the existing collaboration within the Association of Southeast Asian Nations (ASEAN), which has led to initiatives such as regional early warning systems. Mr. Ang added, “This collaborative approach ensures that countries in Southeast Asia are better prepared as interest in nuclear energy deployment continues to grow.”

The Singapore Nuclear Research and Safety Institute is also pivotal in this transition, combining expertise in nuclear technology and safety while cultivating a pool of specialists to address nuclear-related needs. Associate Professor Chung Keng Yeow, the institute’s director, noted, “All the preparation work, especially for the institute, building up manpower, sending people on scholarships overseas – so that we start to build at least some human expertise in this area – is already indicating some sort of a start.”

As Singapore forges ahead in its nuclear energy studies, the emphasis on safety, public understanding, and regional collaboration will be essential in shaping the future of energy in the city-state.
