#OTD in 1982, while on duty in the Barents Sea, the Soviet Navy's Northern Fleet Project 705K/Alfa-class interceptor SSN K-123 suffered a release of approx. 2 tonnes of a liquid metal coolant from the reactor into the reactor compartment, leading to a deterioration of the radiation situation.

As a result of the coolant loss she immediately lost the power, surfaced, the power plant was switched into a cooldown mode, power consumption was transferred to the battery & diesel generator, and the accident was reported to the HQ via radio. K-123 was towed to her home base by the rescue ship Altai.

The accident irreparably damaged the reactor so that it had to be replaced & it took nine years to finish the repairs. The cause of the accident was later defined as a clogging of the steam generator tubes with sludge & corrosion damage.
