One of Rosatom's subsidiaries, Atomflot, formally took control over nuclear icebreaker fleet (and auxiliary ships) from the Murmansk Shipping Company. This is probably a positive development - refueling of icebreaker reactors require regular shipments of fresh HEU fuel (see discussion of the icebreaker fleet in Oleg Bukharin's paper). Now that the entire operation is under Rosatom control, it could (in theory at least) make it safer.
