Sister Lab Program: Unlocking Indonesia's Nuclear Research Potential
A Partnership for Future Energy
Introduction: A Partnership for Future Energy
In the global quest for sustainable and clean energy solutions, international collaboration serves as the cornerstone of innovation. The Sister Lab Program represents a powerful model for fostering such cooperation, creating bridges between research institutions across the world to share knowledge, resources, and expertise.
This article explores the remarkable potential of Indonesia as a nuclear research partner through this program. Despite being an archipelago nation with abundant renewable resources, Indonesia has developed substantial nuclear infrastructure and expertise over decades, positioning itself as an increasingly important player in the global nuclear research community. By examining Indonesia's nuclear profile, we uncover why it represents such a valuable collaborative opportunity for research institutions worldwide.
Key Insights
- Indonesia has over 60 years of nuclear research experience
- Three operational research reactors
- Advanced molten salt reactor project underway
- Strong regulatory framework established
Indonesia's Nuclear Landscape: A Journey of Steady Development
Historical Foundations and Regulatory Framework
Indonesia's engagement with nuclear technology began not with power generation, but with research and applications across various sectors. The country's formal nuclear journey started in 1958 with the establishment of BATAN (Badan Tenaga Nuklir Nasional), the state nuclear research and development agency 4 .
The regulatory landscape evolved significantly with the passage of the Nuclear Energy Act (Law No. 10/1997) in 1997, which established BAPETEN (Nuclear Energy Regulatory Agency) as the independent regulatory body 4 .
International Commitments
- Treaty on the Non-Proliferation of Nuclear Weapons (1970)
- Comprehensive Nuclear-Test-Ban Treaty (2011)
- IAEA Member State
Current Research Infrastructure and Capabilities
Indonesia has maintained three research reactors that form the backbone of its nuclear research infrastructure:
| Research Reactor | Location | Capacity | Primary Functions |
|---|---|---|---|
| RSG-GA Siwabessy | Serpong | 30 MW | Multipurpose research, isotope production, material testing |
| TRIGA Mark II | Bandung | Not specified | Training, research, isotope production |
| Kartini | Yogyakarta | Not specified | Research, education, training |
Research
Advanced materials science, neutron physics, and nuclear applications
Education
Training programs for nuclear scientists and technicians
Applications

Indonesia's Energy Context and Nuclear Power Aspirations
The Energy Challenge
Indonesia faces a significant energy challenge as its electricity demand grows rapidly alongside economic development. While per capita electricity consumption has increased substantially from about 5,500 kWh in 2000 to approximately 10,100 kWh in 2023, it remains below neighboring countries 3 .
The country relies heavily on fossil fuels, which account for about 80% of its electricity generation, creating a strong impetus for diversification 3 .

Nuclear Power Development Plans
Indonesia's nuclear power ambitions have evolved through various phases:
- Initial proposals in the 1990s focused on large-scale plants on Java
- More recent interest in small modular reactors and advanced designs
- Current focus on molten salt reactor technology through the Thorcon project
| Year | Key Development | Target Capacity/Timeline |
|---|---|---|
| 2006 | Presidential Decree outlining nuclear power plants | 4,000 MW by 2025 |
| 2014 | National Energy Policy | Nuclear included as new renewable energy |
| 2022 | Government announcement | First nuclear plant by 2039 |
| 2024 | Site identification | 29 possible sites proposed |
| 2025 | Thorcon licensing process | Operational target: 2032 |
The Thorcon Project: A Case Study in Advanced Reactor Development
Project Overview and Design
The most advanced nuclear power project in Indonesia currently is the ThorCon molten salt reactor proposed by PT Thorcon Power Indonesia. This project represents a significant shift from traditional nuclear approaches, utilizing advanced molten salt reactor technology originally developed by the U.S. Department of Energy's Oak Ridge National Laboratory in the 1960s .
The ThorCon design features the ThorCon 500, a 500 MWe power plant comprised of two low-enriched-uranium-fueled 250 MWe reactors housed in replaceable, sealed "Cans" .

Licensing Progress and Site Evaluation
In a landmark development for Indonesia's nuclear program, BAPETEN granted regulatory approval to ThorCon's site evaluation plan and site evaluation management system in 2025 . This approval marked the first-ever nuclear power plant-related licensing approval from the Indonesian government .
Site Identification
Kelasa Island, Bangka Belitung Province
Preliminary surveys identified it as "a strong candidate" for the plant
Site Evaluation
Focus on safety, ecological, and suitability factors
Promising initial results reported
Next Steps
Obtaining site license and design approval
Potential construction start in 2027, full power operation by 2031
Collaborative Research Opportunities Through Sister Lab Programs
The Sister Lab Program, designed to "link graduate students who are based in different laboratory groups but have similar research foci," presents exceptional opportunities for international collaboration with Indonesian nuclear researchers 1 . This program facilitates "transfer of specific research expertise, collaborative research, transfer of materials such as pdf versions of journal articles, and possibly visiting field sites" 1 .
