Rare Materials Plant (RMP)
The Rattehalli Rare Materials Plant (RMP) is located near Mysore in Karnataka state. This pilot-scale gas centrifuge uranium enrichment plant, with several hundred centrifuges, is generally believed to be capable of producing several kilograms of HEU each year. The two US-built light water reactors at Tarapur are the only civil reactors in India that require low-enriched uranium fuel. All other Indian power reactors use natural uranium fuel and heavy water as a moderator. Consequently, India does not have large-scale uranium enrichment facilities. The unsafeguarded facility, which was built in the late 1980s, is reported to be intended to enrich uranium for future use in fuelling nuclear-powered submarines.
It is reported that indigenously enriched uranium was used in the two low-yield weapons tested in 1998, leading to speculation that the material may have been obtained Rare Materials Plant in Mysore, site of BARC's uranium enrichment plant, or possibly from the Fast Breeder Test Reactor (FBTR) project at the Indira Gandhi Centre for Atomic Research (IGCAR) in Kalpakkam. However, most of the fissile material used in the tests probably came from BARC in Trombay.
This facility is poorly localized, and the NIMA GeoNet Nameserver has never heard of any place of remotely similar designation.
