Kalpakkam is a township in Tamil Nadu, India, situated on the Coromandel Coast 70 kilometres south of Chennai. A conglomerate of two villages (Puduppattinam and Sadurangappatinam) and a DAE township, it is about 55 kilometres (34 mi) from Thiruvanmiyur and 85 kilometres (53 mi) from Pondicherry. This coastal town is humid. Summers here prevail from early March till late May. Temperatures in the Summer vary from 32 degrees Celsius and can go up to 41 degrees Celsius. There is no particular Monsoon season for Kalpakkam as rains are unpredictable here, although there is heavy rainfall in the months of October and November, usually turning into a storm. The coolest months are December and January. A study by the Madras Atomic Power Station(MAPS) revealed that the pollution in Kalpakkam is very low, which when compared to the neighbouring city Chennai is 50 times less.
Kalpakkam is known for its nuclear plants and affiliated research installations. These include the Madras Atomic Power Station (MAPS), a nuclear power plant, the Indira Gandhi Centre for Atomic Research (IGCAR), an affiliate of the Department of Atomic Energy (DAE) and the Bhabha Atomic Research Centre (BARC). Kalpakkam hosts the only nuclear plant in India with a Fast Breeder Test Reactor (FBTR) and a Pressurised Heavy Water Reactor (PHWR).
Due to increasing congestion in Kalpakkam arising from the need to accommodate more employees, a new township of Anupuram/Amaipakkam, 8 kilometres (5.0 mi) from Kalpakkam, was inaugurated in 1998.
On December 26, 2004, the tsunami caused by the 2004 Indian Ocean earthquake generated widespread damage and resulted in 200 deaths in and around Kalpakkam. There is a tsunami memorial having a white oval plaque engraved with the names of 39 people who lost their lives in the tsunami.
