Troubleshooting & upgrading a mission-critical legacy power plant.

About Madras Atomic Power Station (MAPS)

MAPS is a nuclear power plant with fuel reprocessing and waste treatment facilities located 80 km south of Chennai. It is India’s first indigenously developed nuclear power station, with two energy production units deployed in 1983 and 1985. With three more units planned in the future, the facility currently generates 2,311 GW·h every year – enough to power nearly 3 million homes.
