USSR ICEBREAKER

The atomic powered icebreaker Sibir was recently launched at Leningrad's Baltic shipyard. The Sibir is the second atomic powered icebreaker in the series started by the shipyard in the past five years and is being built to the same plans and specifications as the Arktika, which has already been in operation in the Arctic Ocean this winter. Tests are currently under way at the Arctic Insitute in Leningrad for operational laboratory simulation of 120,000 to 140,000 hp icebreakers. It has recently been revealed that the Arctic Institute carries out model tests of all icebreakers built in the USSR and abroad. The icebreakers currently under construction for the USSR in Finland, having 36,000 hp diesel electric engines, were tested at this Institute and earlier vessels in the same series called the Yurmak, the Admiral Makirov and the Krasin were also subjected to model tests before they were built. The model is capable of generating different types of ice which can simulate very open pack conditions and can also range to simulated old ice packs of many years. The temperature in the laboratory can, reportedly, reach 40 degrees below zero.
