* Follows calls for modification by nuclear safety bodies

* Shares close almost 4 percent down

PARIS, Nov 3 (Reuters) - A new generation of French nuclear power reactors came under attack on Tuesday as opposition parties called for an inquiry into their security systems, after three nuclear safety bodies asked for changes to their design.

In a rare joint statement, nuclear safety bodies in France, Britain and Finland on Monday ordered France's Areva (CEPFi.PA: Quote, Profile, Research) and EDF (EDF.PA: Quote, Profile, Research) to modify the safety features on its European Pressurised Reactors (EPR) due to insufficient independence between the day-to-day systems and the emergency systems.

Opponents to nuclear power latched on to the news, with France's opposition socialist party calling for a parliamentary inquiry.

CAP21, a political party founded by Corrine Lepage, a former environment minister, also said more investment should be made in renewable energy rather than nuclear.
