KAMINI (Kalpakkam Mini reactor) is a research reactor at Indira Gandhi Center for Atomic Research in Kalpakkam, India. It achieved criticality on October 29, 1996.[1] Designed and built jointly by the Bhabha Atomic Research Centre (BARC) and Indira Gandhi Centre for Atomic Research (IGCAR)[2] it produces 30 KW[3] of thermal energy at full power.

KAMINI is cooled and moderated by light water, and fueled with uranium-233 metal produced by the thorium fuel cycle harnessed by the neighbouring FBTR reactor.

As of 2006, it is the world's only thorium-based experimental reactor.

KAMINI was the first and is currently the only reactor in the world designed specifically to use Uranium-233 fuel. Use of the large Thorium reserves to produce Nuclear fuel is a key strategy of India's nuclear energy program.
