Singapore's Deepening Nuclear Energy Research Capabilities

Singapore is actively enhancing its expertise in nuclear energy research, even while the extent of regional neighbors' advancements in nuclear power development remains unconfirmed. This initiative is driven by Singapore's energy goals and the potential impact of regional nuclear developments.

Role of Nuclear Power in Singapore's Energy Independence

Professor Lawrence Williams, Chair of the National Environment Agency's Nuclear Safety Advisory Panel, believes nuclear energy has a role to play in Singapore's pursuit of energy independence. He highlights that Singapore, as an advanced industrial nation, has significant energy demands, and prosperity is directly linked to energy consumption. Therefore, exploring all energy options, including nuclear, is a prudent governmental approach. While no decision has been made regarding a nuclear power program, investigating future options is considered sensible. Furthermore, in the context of climate change, nuclear energy is recognized as a low-carbon energy source, positioning it as a potentially important contributor to Singapore's energy mix.

Addressing Concerns: Nuclear Waste Management and Public Perception

Concerns regarding nuclear waste management and public apprehension about living near nuclear plants are acknowledged. Professor Williams suggests that these issues can be addressed through education and clear communication, explaining the nature of nuclear energy and nuclear waste. He emphasizes that nuclear power is a high energy-dense medium, resulting in a relatively small amount of waste compared to the electricity generated, especially when contrasted with other forms of industrial or domestic waste. While public concern exists, waste management is considered a manageable aspect. He points to countries like the United Kingdom, France, Sweden, and Finland, which are in advanced stages of developing underground waste depositories, indicating that waste is not an insurmountable obstacle to nuclear power adoption.

Regional Nuclear Developments and Their Impact on Singapore

Many Asian countries, including China, India, Indonesia, and Vietnam, are expanding their nuclear footprints. Professor Williams stresses the importance of Singapore developing its own nuclear capabilities, irrespective of a domestic nuclear power program. This capability allows Singapore to:

• Understand Nuclear Technology: Possess the knowledge to comprehend nuclear technology and its associated risks.
• Act as an "Intelligent Observer": Be informed about regional developments and their implications.
• Influence Neighbors: Engage with neighboring countries developing nuclear programs to potentially influence their approaches.
• Assess Impact: Gain a deep understanding of what these regional developments would mean for Singapore.

Professor Williams' role as chairman of the nuclear safety advisory panel is seen as instrumental in building this national capability.

Importance of Nuclear Safety Agreements and International Cooperation

Singapore's involvement in nuclear safety agreements, both regionally and globally, is crucial for staying informed and sharing vital information. International cooperation is deemed essential for Singapore, advanced nuclear nations, and Singapore itself. While Singapore has a strong foundation with good universities and skilled engineers and scientists, sharing knowledge and experience with countries possessing more advanced nuclear programs is considered absolutely vital.

Evaluating Nuclear Energy as a Viable Option for Singapore

When considering nuclear energy as a potential source for Singapore, a balanced assessment of benefits and costs is necessary.

Benefits:

• Energy Security and National Security: Singapore relies heavily on energy, and its current primary source for electricity production is gas (hydrocarbons). These resources are finite, and their impact on climate change is a known factor. As gas supplies dwindle, prices are expected to rise. Nuclear energy, alongside solar and wind, presents an alternative for ensuring energy security and, by extension, national security.
• Advantages in Singapore's Geography: Compared to solar and wind, nuclear energy offers certain advantages given Singapore's geographical constraints.

Disadvantages/Considerations:

• Public Conviction: A significant challenge is convincing the public about the safety of nuclear energy.
• Maturity of Technology: Professor Williams notes that nuclear technology is mature, with approximately 450 nuclear reactors operating globally, accumulating over 20,000 reactor-years of operation with a generally safe track record. The key to safety lies in proper design, construction, operation, and the presence of a strong regulatory body.

Conclusion

Singapore is proactively building its nuclear energy research capabilities and fostering international cooperation in nuclear safety. This strategic approach aims to ensure energy security, address climate change concerns, and maintain an informed position regarding regional nuclear developments. While challenges like public perception and waste management exist, they are considered manageable through robust safety protocols and international collaboration. The exploration of nuclear energy is presented as a prudent step in diversifying Singapore's energy portfolio for long-term prosperity and security.
