Singapore Expands Nuclear Studies and Workforce Amid Energy Needs

Singapore is actively enhancing its nuclear energy research and workforce as it explores the potential of nuclear power to meet the nation’s growing energy demands. The government has not established a definitive timeline for nuclear energy deployment, but officials emphasize that safety standards and public confidence are critical challenges that must be addressed.

Mr. Chia Meng Hwee, deputy director of the Energy Market Authority’s (EMA) Nuclear Energy Office, highlighted the emotional aspect surrounding nuclear energy discussions. He 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 added that successful implementation in the region could enhance public trust in nuclear technologies, while setbacks could have the opposite effect.

95 percent of Singapore’s electricity is currently generated from natural gas, which makes the country vulnerable to fluctuations in global energy prices and supply chain disruptions. As energy demands rise, the need for cleaner and more reliable alternatives has become increasingly urgent. Observers suggest that traditional energy solutions may not be suitable for Singapore’s unique constraints, prompting a shift towards innovative approaches.

Nuclear Technology Innovations

In response to these challenges, the EMA has engaged consultancy firm Mott MacDonald to conduct a study on nuclear energy technologies. The development of small modular reactors (SMRs) has emerged as a promising option for Singapore. SMRs are designed to be smaller, faster, and more cost-effective to build than traditional large-scale reactors, which can take nearly a decade to construct.

These compact reactors require significantly less land and can be easily scaled. Their prefabricated components can be transported and assembled on-site, which reduces construction time and costs. Each SMR has a generating capacity of approximately 300 megawatts, about a third of that of conventional reactors. Countries like Russia and China already operate SMRs, with projects progressing in the United States, Canada, and the United Kingdom.

Dr. Ming Tan, global nuclear practice lead at Mott MacDonald, affirmed that safety remains a top priority. “For us, safety is absolutely non-negotiable,” he stated. The focus will be on the safety features and design advancements of SMRs, as well as their progress through licensing and regulatory processes. Dr. Tan emphasized the importance of developing an evidence-based understanding of these technologies before potential implementation in Singapore.

Safety Monitoring and Regional Cooperation

As part of its commitment to safety, Singapore has established a national radiation monitoring programme. This initiative includes a network of stations that continuously monitor air quality for anomalies that may indicate nuclear radiation. Additionally, soil and water samples are tested for radioactivity levels that could pose risks to human health.

The monitoring programme not only serves Singapore but also enhances detection capabilities as interest in nuclear energy grows across the region. Countries such as the Philippines and Indonesia are taking preparatory steps towards operating nuclear power plants. Mr. Ang Kok Kiat, group director for radiation protection and nuclear science at the National Environment Agency, noted the importance of regional cooperation in nuclear safety. “We are catalysing nuclear safety cooperation among our counterpart regulators in the region,” he said.

This collaborative effort is supported by the Association of Southeast Asian Nations (ASEAN), which has facilitated the development of regional early warning systems. Mr. Ang emphasized that such cooperation ensures countries in Southeast Asia are better prepared as interest in nuclear energy continues to rise.

The Singapore Nuclear Research and Safety Institute is also playing a crucial role in building expertise in nuclear technology and safety. Its director, Associate Professor Chung Keng Yeow, highlighted the importance of training and developing specialists to meet nuclear-related needs. He stated, “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 navigates the complex landscape of nuclear energy, its efforts to enhance research, workforce capabilities, and public engagement signal a proactive approach to addressing future energy challenges. The road ahead may be filled with hurdles, but the commitment to safety and public confidence will be pivotal in shaping the nation’s energy future.
