Bulgaria's state-owned energy company will enter negotiations with Toshiba Corp. on financing for building a new reactor at its only nuclear power plant, local media reports said.

Under a government-approved plan, Bulgarian Energy Holding EAD will ask the heavy machinery maker to provide up to 30 percent of the funding for the project at the Kozloduy power plant, the Bulgarian News Agency said.

Toshiba's U.S. affiliate Westinghouse Electric Co. signed a memorandum in 2011 with the Bulgarian firm to cooperate in extending the life of reactors 5 and 6, and decontaminating and decommissioning units 1 to 4, which are already idle. It has also shown interest in accepting an order for the new reactor.
