Baltic Shipyard (USC) has completed a key stage of the mooring trials of the universal nuclear icebreaker "Chukotka": specialists launched two of the three emergency diesel generators (ADG). The test was carried out as normal, confirming the readiness of autonomous power supply systems for emergency situations.
Each of the three emergency diesel generators installed on the vessel weighs 980 kg and produces a nominal power of 250 kW. The units are activated automatically when the reactor emergency protection is triggered. Their tasks are reduced to three key functions: sending a signal to start the backup diesel generators, providing power to emergency lighting, and supporting the operation of critical pumping groups.
Backup diesel generators, which are part of the icebreaker's main power system, take over the full power supply of the vessel in the event of a reactor shutdown. This multi-level scheme guarantees the safety of the crew and the safety of equipment even in abnormal operating modes.
"Chukotka" is the fifth universal nuclear icebreaker of the 22220 project series, being built at the Baltic Shipyard. The vessel was laid down in December 2020, and launched in November 2024. Icebreakers of this project are capable of overcoming solid ice up to three meters thick and provide year-round navigation in the western sector of the Arctic, including the key routes of the Northern Sea Route.
