Chennai: The third round of talks between the central expert group and the state committee to break the logjam over Koodankulam Nuclear Power Plant (KNPP) on Thursday did not make any headway, as an anti-KNPP activist termed it 'not satisfactory.'

"They did not give us the documents we asked for. They even said that they found it difficult to get some of the documents. We have asked them to continue the talks with our expert committee, for which they have not answered. The talks were not satisfactory," M Pushparayan, an anti-KNPP activist and a member on the state committee, told.

"Without giving the documents as asked for, how can they allay the fears?" he added.

The central expert group gave a 75-page report to the protesters, while the latter gave a 70-page counter to the 38-page report which the central team gave them during the second meeting on November 18, he said.

The two-hour meeting at the District Collectorate in Tirunelveli ended without announcing when the next meeting will take place.

The previous two meetings of the committees on November 7 and 18 had failed to break the impasse as representatives of the agitators wanted more information and documents relating to their safety concerns.

The central committee was set up to allay fears of the locals over the nuclear power plant after the prolonged protests delayed the commissioning of the reactor scheduled for this month to March next year. Only essential maintenance operations were underway at the plant.

Meanwhile, People's Movement Against Nuclear Energy (PMANE), spearheading the stir against the KNPP, said it would observe 'black day' for three days in Koodankulam and other areas during Prime Minister Manmohan Singh's visit to Russia.

Protesters will observe a fast and hoist black flags atop their houses for three days from on Friday, S P Udaykumar, Co-ordinator of the movement, told reporters at Coimbatore.
