The IPHWR-220 (Indian Pressurized Heavy Water Reactor-220) is an Indian pressurized heavy-water reactor designed by the Bhabha Atomic Research Centre.^[1] It is a Generation II reactor developed from earlier CANDU based RAPS-1 and RAPS-2 reactors built at Rawatbhata, Rajasthan. It can generate 220 MW of electricity. Currently, there are 14 units operational at various locations in India. It is being used as a base for designing the Bharat small modular reactor (BSMR), for captive use by companies.^[2]

The IPHWR design was later expanded into 540 MW and 700 MW designs, as well as the AHWR-300 design.
