The People's Movement Against Nuclear Energy is an anti-nuclear power group in Tamil Nadu, India, founded by S. P. Udayakumar. Since September 2011 the aim of the group is to close the Kudankulam Nuclear Power Plant site and to preserve the largely untouched coastal landscape, as well as educate locals about nuclear power.
On 10 September 2012 around 1,000 anti-nuclear protesters tried to march towards the plant. The police responded with tear-gas shells.
