A confidential 2002 report by the Department of Atomic Energy (DAE) says there is a lineament - a geological feature that can turn out to be a faultline, a crack or even a fissure - running across the Madban plateau in Ratnagiri where the Jaitapur nuclear power plant is to be built.
Neither the DAE nor the Nuclear Power Corporation of India Private Limited (NPCIL) has revealed the existence of such a geological feature on the site of the Jaitapur Nuclear Power Project.
To a detailed questionnaire on the report's findings, NPCIL said: "All lineaments need not be faults. After studying the past seismicity data and data on offshore faults, it has been established that there is no capable fault [one which has the ability to cause an earthquake] within 5km of the plant site."
The NPCIL is a public sector undertaking under the DAE, which will build and operate the Jaitapur nuclear plant. The project, touted to be the biggest nuclear power park in the world, will house six European Pressurised Reactors of 1,650 megawatts each, provided by French nuclear giant Areva under the Indo-French civilian nuclear pact.
