The Kalpakkam Atomic Reprocessing Plant (KARP) is one of three major fuel reprocessing facilities in India. This indigenously built plant began cold commissioning (operating without spent fuel) in March 1996 and later initiated spent fuel reprocessing by the end of the year. KARP currently reprocesses spent fuel from two pressurized heavy water reactors (PHWRs) at the Madras Atomic Power Station (MAPS) in Kalpakkam and the Fast Breeder Test Reactor (FBTR). While the reprocessing plant utilizes the plutonium-uranium extraction (PUREX) process, it also employs laboratory-scale facilities to process plutonium-uranium carbide fuel from the FBTR. During the late 1990s, KARP was earmarked to meet plutonium requirements for the new Prototype Fast Breeder Reactor (PFBR) being developed at IGCAR.

It is unclear whether KARP provides plutonium for India's nuclear weapons program. The facility is not under International Atomic Energy Agency (IAEA) safeguards.
