"We shouldn't wait for studies, opinions from third parties, because we are starting to look pathetic," the president said at her annual news conference.
"I think that Lithuania looks bad both at home and in the international context, because it is unable to make strategic decisions, which are up to Lithuania itself to make. We cannot push this decision on to either Estonia, or Latvia, or the Swedes," she said.
"It is up to us to decide whether or not we are going to remain a nuclear energy country - in the strategic sense," the president said.
Lithuanian Prime Minister Algirdas Butkevičius has said on Wednesday that the government is waiting for a study by Swedish experts on the integration of all EU electricity networks, which he said would answer the question regarding a need for a nuclear power plant.
Estonian President Toomas Hendrik Ilves earlier this year criticized Lithuania's position, saying that the project for building a new nuclear power plant in the country had made almost no headway over seven years.
Lithuania's new government, which took office at the end of last year, has not yet made up its mind on the project. It has appointed a working group to look into this issue.
