Sergey Preminin

In Vologda in 2004 named a street in south part of city in memory of Sergei. In Vologda Oblast there are 2 schools named in memory of Sergei (including one school in his hometown, Krasavino). In 2015, in a letter to the Naming and Recognition Committee for National Heroes Day Preminin was also nominated as a national hero of Bermuda.

On 3 October 1986, while on patrol 680 miles (1,090 km) northeast of Bermuda, the K-219 suffered an explosion and fire in missile compartment VI. Three sailors were killed outright in the explosion. The vessel surfaced to permit its twin nuclear reactors to be shut down.

On 23 October 1984, Preminin started to serve in the Soviet Navy. Preminin initially underwent a training in a special group in Severodvinsk, after which he started to serve aboard the K-219.

Sergey Anatolievich Preminin (Russian: Сергей Анатольевич Преминин; 18 October 1965 – 3 October 1986) was a Soviet Russian sailor who, after an explosion aboard nuclear submarine K-219, prevented an impending nuclear meltdown by manually forcing damaged control rods into place. He was, however, unable to exit the reactor compartment because the hatch had jammed due to increased pressure, and died.

Preminin was born on 18 October 1965 in the village of Skornyakovo in Vologda Oblast, then in the Russian SFSR of the Soviet Union. Preminin's father Anatoly was an electrician and his mother Valentina worked in a flax factory. The couple had three sons. Sergei attended school in the city of Krasavino and decided to follow in the footsteps of his older brother Nikolai by graduating from engineering school in Veliky Ustyug in the Vologda Oblast.
