In 1970, the Kalpakkam Power Station marked a significant milestone as India’s inaugural fully indigenous nuclear power facility, comprising two units of Pressurised Heavy Water Reactors (2x 220 MWe PHWR). Nestled in the northern region of Tamil Nadu along the east coast, it rests approximately 70 km south of Chennai, 30 km west of Chengalpattu, and about 82 km north of Puducherry, bordered by the Bay of Bengal.

Tata Consulting Engineers (TCE) secured the role of Consultants for this monumental Power Project commissioned by the Department of Atomic Energy. Their responsibilities encompassed engineering the Deep Sea intake structure and the circulating water system, executing the complete design and engineering of the reactor building and the High Voltage Switchyard, as well as overseeing the comprehensive coordination of the entire project. This included managing other consultants engaged in the project showcasing TCE’s pivotal role in ensuring a cohesive and successful undertaking.

The tasks related to the deep-sea intake structure and reactor building were inherently intricate, incorporating numerous novel engineering features not previously encountered in the country. TCE successfully undertook the challenge, delivering commendable designs and fulfilling the assignments with high technical precision and adherence to the specified schedules mandated by the Department of Atomic Energy. Following this success, the firm earned the responsibility of designing and engineering analogous areas for the Narora Atomic Power Plant in Uttar Pradesh.
