"Our primary demand is the government should institute an independent and transparent national committee on hydrology, geology, oceanography and seismology of the region," PMANE leader M Pushparayan told PTI at nearby Idinthakarai.
Their other demands include conducting disaster management and evacuation exercises in areas around KKNPP falling within a 30 km radius, sharing a copy of the Indo-Russian Inter-governmental agreement in 2008 on nuclear liability. "The government should also release all anti-nuclear peace activists from prison unconditionally and withdraw all false charges against our people," he said.
PMANE had earlier threatened to go on indefinite fast from May 1 alleging that district officials had not kept their promises made last month, including withdrawal of "false" cases against some activists.
A 12-member PMANE team led by Arimavalavan had on Monday held talks with the Collector and highlighted their demands.
PMANE co-ordinator S P Udayakumar and his supporters had on Mar 28 withdrawn their nine-day-long indefinite fast after a delegation led by the Collector agreed to look into their demands. They launched the indefinite fast after the state cabinet on March 19 gave its go-ahead for commissioning of the first of the two reactors.
