The Prosecutor General's Office of Ukraine on December 4 conducted raids at three energy and fuel companies – National Nuclear Generating Company Energoatom, Skhidny Mining and Centrenergo.

Energoatom’s press service told Interfax-Ukraine that raids took place at the company's headquarters and its Atomremontservice, Atomkomplekt and Scientific and Technical Center divisions. Documents concerning Energoatom's cooperation with over 250 enterprises, including OJSC TVEL, Wеstіnghоusе Еlесtrіс Sweden АВ, KPMG Audit LLC, Grant Thornton Legis, etc, were seized by law enforcement.

The director of the external IT communications center at Energoatom, Ilona Zayats, said that the reason for the raids is a criminal investigation that opened in summer 2014, examining the company’s operation during 2012-2013.

She said that Prosecutor General's Office already conducted raids on September 9 and September 10, 2014, as part of the same investigation.

Zayats said that any decision made to proceed with the investigation was based on the documents seized during the first search.

The company said that the seizure of many contract and financial documents hinders the company not only in relation to its normal operation, but in its ability to combat corruption too.

Energoatom is the operator of all four nuclear power plants currently working in Ukraine: the Zaporizhia, Yuzhnoukrainsk, Rivne and Khmelnytsky power plants which contain 15 pressurized light water reactors and a total rated capacity of 13.835 gigawatts.
