* Famous French green activist named ecology minister
* EDF shares drop 2.5 percent on the news
* Hulot pragmatic about nuclear in recent interviews
* Not clear whether Hulot's portfolio includes energy (Adds comment, detail, EDF price move, analyst reaction)
PARIS, May 17 (Reuters) - Environmental campaigner Nicolas Hulot was appointed ecology minister in the new French government on Wednesday, news that sent the share price of nuclear power group EDF down 2.5 percent.
Unlike his predecessor Segolene Royal, who was minister of energy and environment, Hulot's job description does not formally mention energy.
It was not immediately clear whether Hulot's formal title of "Minister of Ecology and Solidarity" included energy, and notably the oversight of France's state-owned nuclear industry.
Hulot, France's best-known environmental campaigner who systematically scores high in popularity polls, said that being a minister is not a goal in itself.
"I think, although I am not sure, that the new political situation offers an opportunity for action and I cannot ignore that," Hulot, 62, said on his Twitter feed.
He added that the urgency of the situation obliged him to try everything to bring about a new social model.
As an environmental envoy for outgoing Socialist President Francois Hollande, Hulot helped prepare the 2015 United Nations COP21 climate summit in Paris, but rejected Hollande's repeated requests to become a minister.
A pragmatist, the former documentary TV reporter has advised French governments from the right and the left about environmental policies and has generally good relations with the French business world, which sponsors his foundation.
Hulot has been critical of nuclear energy, but is not known specifically as an anti-nuclear campaigner.
In an interview with Le Parisien newspaper in early March, Hulot took a pragmatic approach to nuclear energy. Asked whether he would demand France abandon the use of nuclear energy, he said: "That is a medium-term target".
"As renewable energy becomes more and more competitive, the nuclear industry business model belongs to the past," he was quoted as saying.
Asked about a possible closure of the Fessenheim nuclear plant, which Hollande promised but did not implement, Hulot said the closure of Fessenheim was important but would have a social cost.
"We cannot impose a transition by force. The transition has to be done in an acceptable manner," he said.
EDF shares, down 2.5 percent at 9.23 euros just before the announcement, fell further and stood more than five percent lower on the day within half an hour of trading following the news of Hulot's nomination.
"The market is reacting negatively to Hulot's appointment. There is a fear of a stricter ecological line given Hulot's history as an environmental campaigner," said Andrea Tueni, markets analyst with Saxo Bank.
