تاريخ كسارات الجليد النووية

Nuclear-powered icebreaker Lenin

The first nuclear icebreaker was the Soviet vessel Lenin, which was launched in 1957 as the world’s first nuclear-powered surface vessel and the first civilian-operated nuclear vessel.[1] An experimental nuclear-powered vessel, Lenin began icebreaking service along the Northern Sea Route in 1959 and continued to do so until 1989.[2] From 1967 to 1971 Lenin was refurbished, with new capabilities developed in the process.[3]

The second-generation nuclear-powered icebreakers, Arktika class (Project 10520 and 10521), utilized an improved reactor design and turbo-electric propulsion train to deliver significantly improved icebreaking performance, allowing the vessels to provide year-round icebreaking service along the Northern Sea Route and conduct voyages into the Arctic Ocean.[بحاجة لمصدر]

As natural gas exploration increased along the Siberian coast, the Murmansk Shipping Company (MSCO) found that the existing Arktika-class were challenging to operate within the shallow coastal deltas. To fill this capability gap, they ordered two slightly smaller shallow-draught icebreakers from Wärtsilä Marine Helsinki Shipyard in Finland and installed their nuclear powerplants at Baltic Shipbuilding in Leningrad (today St. Petersburg).[بحاجة لمصدر]

In the late 1980s, the Central Design Bureau "Iceberg" began designing a replacement for the Arktika- and Taymyr classes. The program called for a series of icebreaker designs ranging from smaller diesel-powered auxiliary icebreakers to two nuclear-powered icebreaker types, 60-megawatt "line icebreaker" (LK-60Ya) and 110-megawatt "icebreaker-leader" (LK-110Ya).[4]

Project 22220 icebreaker, Ural, under construction

The LK-60Ya was realized as Project 22220, the first of which was laid down in 2013 and commissioned in 2020. Although similar in size and propulsion power to the preceding Arktika-class, Project 22220 is a dual-draft vessel capable of operating at 2 metres (6.6 ft) shallower draft, allowing it to perform roles of both Arktika- and Taymyr classes.[5] The first LK-110Ya-type icebreaker, realized as Project 10510, was laid down in 2021. When completed, the lead vessel Rossiya will be the largest nuclear icebreaker in the world.[6]

Although Russia has historically been the only country to build and operate nuclear-powered icebreakers, several other countries have expressed interest in doing so. In 2019, China announced plans that it would build a nuclear-powered icebreaker similar to the Russian Project 22220.[7] As of 2023, construction on this proposed nuclear icebreaker has not commenced.[8]

The Northern Sea Route runs along the Siberian coast from the principal ports of Murmansk to Petropavlovsk and Vladivostok. The route includes sections of the Barents Sea, the Pechora Sea, the Kara Sea, the Laptev Sea, and the Eastern Siberian Sea to the Bering Strait. It provides the only feasible means to deliver heavy equipment, such as natural gas production modules or military vehicles, to communities along the Siberian coast and the Russian Arctic islands. Key ports served along the Siberian coast are Dikson, Tiksi, Pevekوشبه جزيرة يامال.[بحاجة لمصدر]

During the winter, the ice along the Northern Sea Route varies in thickness from 1.2 to 2.0 metres (3.9 to 6.6 ft). The ice in central parts of the Arctic Ocean is on average 2.5 metres (8.2 ft) thick. Nuclear-powered icebreakers can force through this ice at speeds up to 3 knots (5.6 km/h; 3.5 mph). In ice-free waters, the maximum speed of the nuclear-powered icebreakers is as much as 22 knots (41 km/h; 25 mph).[بحاجة لمصدر]

Two types of nuclear-powered icebreakers are used along the Northern Sea Route: the heavy Arktika-class and shallow draft Taymyr-class.[needs update] With a draft of 11 metres (36 ft) the Arktika-class vessels are unable to navigate the shallow river deltas leading to several key Siberian ports. The smaller Taymyr-class provides icebreaking service in these regions, particularly the Yenisei River to Dikson.[بحاجة لمصدر]

الاستكشاف العلمي

The icebreakers have also been used for a number of scientific expeditions in the Arctic. On August 17, 1977, Arktika was the first surface vessel in the world to reach the North Pole.

Since 1989 the Arktika-class nuclear-powered icebreakers have also been used to ferry tourists to the North Pole. Each participant pays up to US$25,000 for a cruise lasting three weeks. Sibir was used for the first two tourist cruises in 1989 and 1990. In 1991 and 1992, the tourist trips to the North Pole were undertaken by Sovetskiy Soyuz. During the summer of 1993, Yamal was used for three tourist expeditions in the Arctic. The last two vessel of the Arktika-class (Yamal and 50 Let Pobedy) contain a separate accommodation section for tourists.

Quark Expeditions chartered 50 Let Pobedy for expeditions to the North Pole in 2008. The vessel's maiden voyage to the North Pole embarked in Murmansk, on June 24, 2008. The ship carried 128 guests in 64 cabins in five categories. 50 Let Pobedy completed a total of three expeditions to the North Pole in 2008 for the polar adventure company. As of February 2013, Quark Expeditions was listing 50 Let Pobedy in the company fleet[9] and offering it for a North Pole cruise.[10]

Russia's nuclear-powered icebreaking fleet is owned by the federal government. Initially, the icebreakers were operated by the Murmansk Shipping Company (MSCO); however, in 2008 they were transferred to the state-owned corporation Rosatom and operated by the subsidiary Atomflot.[11] Rosatom is also responsible for the safe navigation of vessels along the Northern Sea Route.[12]
