The remaining 7.7 percent of respondents did not know or had no opinion.
Some 28.9 percent of those polled fully supported the Visaginas nuclear power plant construction plans and 33.5 percent were totally opposed. Another 16.8 percent were fairly in favor and 13.1 percent were fairly opposed.
Factus polled 1,076 people in early April. It did not say who ordered the poll.
Another poll carried out by Vilmorus for the Green Policy Institute in May showed that almost two-thirds, or 65 percent, of Lithuanians were against building a new nuclear power plant and 21.5 percent were in favor. The remaining 13.5 percent had no opinion.
The Vilmorus survey showed that the Lithuanian population's opinion on the nuclear power plant issue had changed radically since the first poll on this subject in 1989.
According to the Internet news site Iq.lt, those polled back in 1989 said that the country needed the Ignalina nuclear power plant, even though it had been only three years since the Chernobyl nuclear disaster and the Green movement in the country was apparently as strong as ever.
