Due to a lack of transparency surrounding the project, this progress is ringing alarm bells anew among nuclear watchdogs. The most immediate concern is the vessel's movement once fueled. Akademik Lomonosov is not considered a nuclear installation under Russian law until it's actually moored and made operational in Pevek, says Haverkamp. As a result, Russia's nuclear regulator has not overseen construction, testing, fueling, or transport of the ship from its home port to its final destination. "Insufficient regulatory oversight plays a role in most severe nuclear incidents," he said, noting that Greenpeace has "demanded" that Rosatom, the ship's manufacturer, and the Russian government allow the nuclear supervisory body, Rostechnadzor, access to the project. It has also requested peer review from international organizations.
