Russia initially planned to reactivate and by 2020, but it was later indicated that the condition of the reactor cores of both ships was such that it would prove difficult, expensive and potentially dangerous to remove the spent nuclear fuel and repair the cores. As a consequence, it is likely that both ships will be scrapped. The modernization of "Admiral Ushakov" seems unlikely due to an alleged nuclear incident which may have left one of its reactors damaged with scrapping to start in 2016 or later. Other sources disagree, stating that all four ships will be modernized and returned to service. In 2014 some maintenance work was performed on "Admiral Lazarev" (the only cruiser located in the Pacific). Skepticism was expressed regarding the ability of Sevmash shipyard to simultaneously modernize two "Kirov"-class battlecruisers.
