PARIS, July 27 (Reuters) - France's ASN nuclear watchdog on Wednesday said it backed the general strategy being undertaken by power company EDF to fix corrosion issues at its nuclear power plants.

The ASN added that EDF could still, nevertheless, speed up and improve its oversight of the Belleville plant.

The French government is in the process of fully nationalising EDF.

Bringing EDF back under full state ownership would give the government greater licence to restructure the debt-laden group that runs the nation's nuclear power plants.

EDF has been grappling with unplanned outages at its nuclear fleet, delays and cost overruns in building new reactors, and power tariff caps imposed by the government to shield French consumers from soaring electricity prices.
