Advanced heavy-water reactor
The Advanced Heavy-Water Reactor (AHWR) or AHWR-300 is an Indian Generation III+ reactor design developed by the Bhabha Atomic Research Centre and intended to use thorium and plutonium as fuel. The AHWR is an advanced pressurised heavy-water reactor (PHWR), that is designed to require much less mined uranium than present-generation reactors.
