Indonesia has signed several nuclear deals
* In early 2015, they signed a contract to build and test a pebble-bed HTGR at Serpong with a consortium of Russian and Indonesian companies led by NUKEM Technologies.
* in August 2016, they signed a cooperation agreement with China Nuclear Engineering to develop small HTGRs in Kalimantan and Sulawesi by 2027.
* they have signed agreements with Russia's Rosatom to develop a floating nuclear power plant to power smaller inhabited islands.
* in March 2017, three state-owned Indonesian power companies completed a 10-month-long preliminary feasibility study for a 250-MW molten salt reactor that would use a combination of 80% thorium and 20% uranium (the uranium would be enriched to 19.75% U-235, and the fuel would be delivered to the plant as fluoride salts). The reactor is from the ThorCon International nuclear startup. ThorCon is a company owned by Florida-based consulting firm Martingale Inc. The prefeasibility study stems from a memorandum of understanding the company signed with the Indonesian state firms in December 2015.
Indonesia has a lot monazite and Thorium, which is recovered from the country's substantial tin mining industry.
The ThorCon reactor is designed for installation 15 to 30 meters underground.
