Chancellor Angela Merkel of Germany is hosting a summit in Berlin on the issue of nuclear energy.
Ms Merkel wants to reverse a decision of the previous government to close 17 nuclear power stations by 2021.
The BBC reports she is expected to seek a compromise in a row over their proposed life cycle.
A plan to levy a nuclear fuel tax on energy companies will also be discussed.
The Chancellor has proposed to keep the plants running for another 10 to 15 years, arguing that renewable energy sources are not yet sufficiently developed.
However, the BBC reports a row has broken out within her governing coalition and parliament about the best time span.
Opinion polls suggest a majority of Germans would support an end to nuclear power generation.
