It is designed to be self-sustaining in relation to U-233 bred from Th-232 and This will use low-enriched uranium plus thorium as a fuel, dispensing with the reaction, and external air circulation gives decay heat removal. Det är 220Rn (från sönderfallskedjan 232Th, se fråga 13744 ) som sönderfaller till 216Po. Det finns en sönderfallskalkylator på Universal Decay Calculator .

External gamma exposure is not a major concern because thorium emits only a small amount of gamma radiation. Although thorium-229 has a much higher gamma component than either thorium-232 or thorium-230, thorium-229 comprises a very small fraction of natural thorium.
