President Vladimir Putin has signed a decree relieving Dmitry Rogozin of his post as chairman of the supervisory board of state-run nuclear corporation Rosatom.
Boris Gryzlov, currently chairman of United Russia's supreme council, will be his replacement, Interfax reported, citing a hard-to-find document on the Kremlin's website.
Rogozin had apparently asked to be released from the post because of a conflict of interest with his role as a supervisor of Russia's nuclear industry, Interfax reported, citing an unidentified Kremlin source.
A separate source told Kommersant that Rogozin will continue to oversee the nuclear industry but will no longer be involved in Rosatom management decisions.
Rosatom's supervisory board, which consists of nine people, oversees the corporation's development strategy, finances, key performance indicators and strategic issues.
The decree appointing Gryzlov to the Rosatom post was signed Nov. 10 and came into immediate effect, Interfax reported.
Boris Gryzlov previously served as interior minister from 2001 to 2003 and Duma speaker from 2003 to 2011.
