Chennai, Sep 26 (ANI): Anti-nuclear activist Udayakumar demanded ban on construction of unit three and four at Kudankulam nuke power plant in Tamil Nadu. Spearheading the prolonged agitation against the Kudankulam Nuclear Power Project (KNPP) in Tirunelveli district, Udayakumar while addressing mediapersons said that false cases fostered on 227 billion people should be withdrawn immediately. Earlier, the Madras High Court dismissed the petition, challenging the Atomic Energy Regulatory Board's clearance to the plant to load fuel. He also informed that activists will embark upon a train trip from Kanyakumari to Kashmir from November 07 to spread the anti-nuclear message across length and breadth of the country.
