Rosatomflot’s nuclear icebreaker Sibir completed flood control work on the Yenisei River. The crew of the nuclear-powered ship had a task to make additional ice channels and cuts in the riverbed to prevent possible ice jams.
“For the first time, the universal nuclear icebreaker of project 22220 was used for these types of work,” said Leonid Irlitsa, Acting Director General of Atomflot FSUE.
The anti-jamming measures have been taken since May 22 at the request of the administration of the Taimyrsky Dolgano-Nenetsky municipal district of the Krasnoyarsk Territory. According to hydrometeorologists, ice drift on the Yenisei is expected with a rupture wave and jam.
On the Yenisei, the technique of anti-jamming operations with the use of nuclear-powered icebreakers of the Taimyr type has been proven for years. The first thing is the close of the port of Dudinka. After that, all ships are removed from the river. When the water level reaches 7.5-8 meters, the nuclear-powered icebreaker starts making additional channels and cuts with the destruction of the snow-ice road. These works allow avoiding ice jams and water rise above the dangerous levels.
