Norilsk Nickel to help predict behavior of permafrost in the Arctic

11 october 2023

Norilsk Nickel will help predict the behavior of permafrost in the Arctic, said Anton Pryamitsky, Deputy Chief Engineer of the Polar Branch of Norilsk Nickel.

"The company monitors permafrost soils and conducts serious scientific research. These measures will further make it possible to predict how the permafrost will degrade or, conversely, freeze under the influence of climate change," he said.

According to him, Norilsk Nickel experts are actively monitoring how well the permafrost is being restored.

"We use the latest equipment, completely Russian–made – this applies to temperature control systems, predictive analysis, calculation complexes, thermal stabilization systems," Pryamitsky said.

Specialists of the Norilsk Nickel's buildings and structures monitoring center provide all available archival information collected since the 1940s.

Often, Norilsk Nickel experts advise builders right on the site, helping to draw up technical specifications and checking reports on engineering and geological surveys, which allows for high-quality and efficient renovation, Pryamitsky said.
