Northern Ireland Secretary Peter Hain has been asked to clarify whether the North is being considered as a location for the construction of nuclear power stations.
The call has come from the All-Ireland Nuclear Free Local Authorities Forum, which includes local authorities from both sides of the Border opposed to nuclear power.
The forum's move follows the energy review, initiated by British prime minister Tony Blair.
In announcing the review it was stated: "The devolved administrations and territorial departments are already involved and will continue to be involved throughout the course of the review."
The forum has written to Mr Hain asking him to give clear confirmation that "on no account will he allow nuclear power stations be built in Northern Ireland".
While Mr Hain is believed to be one of the British cabinet members who oppose nuclear energy, the forum is concerned that the devolved administrations in Northern Ireland, Wales, and Scotland may be forced to build nuclear power stations whether they want to or not.
The chairman of the forum, Michael O'Dowd (Louth County Council), said: "Civil society must make its voice heard now to oppose construction of a nuclear facility anywhere on our island, and we will be calling on local councils in all parts of Ireland to make their views known.
"Northern Ireland is well positioned to generate a large proportion of its energy from renewable sources, particularly wind power, and there is also scope for energy-saving programmes to have a big impact. Mr Hain must tell Tony Blair that there is no need or desire for any nuclear power station to be built in Northern Ireland."
Down district councillor Margaret Ritchie said: "The Strategic Energy Framework for Northern Ireland, which was published in June 2004 following extensive consultation, emphasises the role that renewable energy can play in meeting Northern Ireland's energy needs.
"There is absolutely no good reason why this should change just because Tony Blair has been seduced by the nuclear lobby into calling yet another energy review."
