icebreaker on Encyclopedia.com In 1959, the Soviet Union launched the first nuclear-powered icebreaker, the Lenin. Icebreakers have been widely used in the exploration of the Arctic and the Antarctic. When the icebreaker charges into the ice at full speed, its sharply inclined bow, meeting the edge of the ice, rises upon it, and the weight of the vessel causes the ice to collapse. www.encyclopedia.com /html/i1/icebreak.asp   (338 words)

Russia Russia's changing political and economic environment since the collapse of the Soviet Union has not left Russia's fleet of nuclear-powered vessels untouched. In the case of the nuclear icebreaker fleet, the shipyards producing these vessels are joint stock companies, with most of the stock state-owned. Stimulated by the US development of the Nautilus nuclear submarine (deployed in 1954), Soviet work on nuclear propulsion reactors began in the early 1950s at the Institute of Physics and Power Engineering (Obninsk) under Anatoliy P. Alexandrov, later to become head of the Kurchatov Institute. www.nti.org /db/nisprofs/russia/naval/overview.htm   (1651 words)

Ships of the World: An Historical Encyclopedia - - Arktika The second nuclear-powered icebreaker built by the Soviet Union after Lenin, Arktika was the first of five vessels in her class. Originally named for the General Secretary of the USSR, she was designed for the sea routes of the Northeast Passage across the top of the Soviet Union; in 1975 she became the first surface ship to reach the North Pole. Sponsored by T. Guzhenko, minister of the merchant fleet of the Soviet Union, the expedition was described simply as a "scientific-practical experimental voyage" intended to test the new icebreaker in more extreme conditions than the ship would ordinarily encounter. college.hmco.com /history/readerscomp/ships/html/sh_007500_arktika.htm   (213 words)

GRACE Nuclear Abolition Project - Star Wars The US and other nuclear powers had exaggerated the difficulty of building nuclear weapons and urgent steps must be taken to prevent terrorist groups getting hold of highly enriched uranium, a leading US nuclear security expert has warned. A nuclear catastrophe could occur if terrorists gained access to nuclear weapons or weapons-grade materials, and if regional conflicts or instability degenerated into wars in which nuclear weapons were used, said a report by researchers at the Carnegie Endowment for International Peace to a Nonproliferation Conference last week. Facing questions about whether terrorists could steal nuclear weapons material or technology, the secretary of energy said Friday that he was considering the creation of a federal police force to replace the private guards used by the weapons program for decades. www.gracelinks.org /nuke/terrorism/archives-2004.php   (2574 words)

The study found that nuclear industry discharges to sea are back at the same level as the early 1950s, and that naturally occurring radioactive materials (NORM) now dominate doses to the European Union (EU) population from industrial discharges, both in terms of alpha activity and collective dose. The strategic nuclear arms reduction treaty calls for the US and Russia to reduce their deployed strategic nuclear warheads by two-thirds down to 1700-2200 each over a ten-year period. www.world-nuclear.org /nb/nb03/nb0320.htm   (1637 words)

Civil Nuclear Powered Vessels The nuclear-powered icebreakers were constructed for the purpose of increasing the shipping along the northern coast of Siberia, in waters covered by ice for long periods of time. The ship was not fitted with a nuclear reactor for propulsion, due to lack of financing, as well as the negative attention that arose concerning nuclear-powered civil vessels in ports in the eastern part of Russia. Demands were raised by the employees that the nuclear-powered icebreakers were to be precipitated as a separate state-run company, economically independent of the MSC. www.bellona.no /imaker?id=7565&sub=1   (6898 words)
