PARIS--Philippe Knoche, chief executive of beleaguered nuclear engineer Areva SA (AREVA.FR), Thursday said companies other than state-controlled power utility Electricite de France SA showed interest in some of its units.

Mr. Knoche didn't name any of the possible buyers.

Areva, which has posted losses for four consecutive years, said it will unveil a new strategic plan before reporting its first half results at the end of July. As part of the new strategy, the firm plans to sell assets and cut investment.

Earlier this week, EDF CEO Jean-Bernard Levy said he would make Areva an offer to buy its nuclear unit Areva NP, which accounts for around 40% of its revenue.

Mr. Levy didn't say how much his company was ready to pay. Mr. Knoche said the company would make sure asset valuations are "good."

After Mr. Levy's comments, Areva Chairman Philippe Varin said the government, which controls more than 80% of both companies, would ultimately make a decision.

French power utility Engie, formerly known as GDF Suez, said it found some Areva assets attractive.

Mr. Varin also said the new strategy, to be announced in July, will focus on the company's core business and development in China.
