West Kalimantan SMR feasibility and FEED study with the United States and Japan

Indonesian reporting describes PLN cooperation with NuScale in West Kalimantan and front-end engineering study work with the United States and Japan. In September 2025 the coordinating minister said the small-reactor feasibility study had been completed. It is separate from Rosatom's floating and land-based proposals for the same province.
