Explanation:
The world’s first floating nuclear reactor Akademik Lomonosov was launched on August 23, 2019, and had set up on a 5000 km journey to northeastern Siberia from Arctic port of Murmansk (north Arctic region), and the trip is expected to last between 4-6 weeks depending on the ice amounts and weather. Despite warnings by environmentalists the journey was started as the reactor is vulnerable to storms and could also produce radioactive wastes.
