Boris Korchilov

Boris Alexandrovich Korchilov (; November 17, 1937, Leningrad, USSR – July 10, 1961, Moscow, USSR) was a Soviet naval officer, engineer-lieutenant, and commander of the remote-control group of the submarine K-19. He died during the liquidation of a nuclear reactor accident in July 1961, preventing a technological catastrophe.

Biography Boris Korchilov was born in 1937 in Leningrad and spent his early years in the besieged city during World War II. He attended the 5th High School in Leningrad.

In 1960, he successfully graduated from the Dzerzhinsky Naval Academy. Following the completion of his studies, Boris Korchilov assumed the role of the remote-control group commander on the submarine K-19.

Nuclear accident

The K-19 submarine accident occurred on July 4, 1961, at 4:07. A crack appeared in the pipeline leading from the first circuit of the nuclear reactor to the pressure sensor, causing a rapid rise in reactor temperature. The crew attempted to increase pressure, but the reactor's temperature continued to rise. During a meeting with the commander of the K-19 submarine, Captain 2nd Rank Nikolay Zateyev, the decision was made to manually create a cooling system to prevent a meltdown. Lieutenant Korchilov volunteered to enter the reactor compartment to conduct welding work.

At 6:50, Boris Korchilov's emergency group descended into the compartment. When they entered the compartment, they saw a blue glow emanating from the pipes of the damaged reactor. They thought a fire had started, but it was shining from the ionized hydrogen radiation. The crew faced lethal radiation doses, but Korchilov, as the senior officer, provided moral support to the sailors installing the emergency cooling system. After hours of strenuous efforts, the temperature was stabilized. Korchilov's actions in averting a nuclear disaster were crucial during this critical operation.

The accident on board the submarine K-19 was classified as a top secret. The irradiated sailors were buried in lead coffins, secretly, without disclosing the burial location even to their relatives. One of the surviving crew members accidentally discovered the burial site (he came to bury a relative and stumbled upon inconspicuous graves). Boris Korchilov was reburied at Krasnenky Cemetery in Saint Petersburg.

Academician A. P. Alexandrov recognized the actions of the crew and Korchilov's group in creating the emergency reactor cooling system as correct and selfless. The system, installed by Boris Korchilov's group on July 4, 1961, in the damaged reactor compartment, was subsequently implemented in the design of all nuclear reactors on navy ships, as well as at nuclear power plants. In the city of Zaozyorsk, one of the streets is named after Boris Korchilov.

In popular culture "K-19: The Widowmaker" is a 2002 historical submarine film directed by Kathryn Bigelow. Actor Peter Sarsgaard played the role of reactor compartment commander engineer-lieutenant Vadim Radchenko, a prototype of Boris Korchilov. // History Channel, December 21, 2016.
