The initiative aims to expand SMR deployment overseas as an alternative to nuclear technologies from Russia and China, with Indonesia identified as a potential destination.

The effort aligns with broader goals to promote international deployment of SMRs and diversify the supply chain for nuclear energy technology in the Asia-Pacific region.

Under a trilateral framework signed by the foreign ministers in July, the United States would lead reactor design, South Korea would lead construction of the power plants, and Japan would supply manufacturing expertise for key plant equipment.

A trilateral collaboration among Japan, the United States, and South Korea is exploring exporting next-generation small modular reactors jointly developed by the three countries to Indonesia as part of a government-backed industrial partnership.

Indonesia has an existing arrangement with Rosatom to operate two floating nuclear power plants, illustrating the regional interest and competition in nuclear energy options.

Other potential deployment sites mentioned include Malaysia and the Philippines, indicating a broader regional rollout strategy.
