Barents Sea
Remember those helicopter groups we signed up for? Well, these groups weren’t used just for heli ops, but for other events and activities as well.
One such activity was a tour of 50 Let Pobedy’s engine room, including a peek into the reactor compartment and a visit to the control room. These tours have been taking place since our first day at sea. Our turn to travel into the deep recesses of the ship finally came today.
Vladimir Judin — Chief Engineer — speaks to us about the technical aspects of
the ship before taking us down to see the inner-workings of 50 Let Pobedy.
The tour started in a conference room where Chief Engineer Vladimir Judin spoke to us — through Irina, the translator. Funny coincidence — the suite we’re staying in is normally where he is quartered … we assured him we would be leaving it in good shape for him to take up residence again after we disembark tomorrow.
Vladimir covered some of the technical aspects of the ship and answered our questions before leading us down to and around areas of the ship that are normally off-limits to passengers. The high level of noise from the machinery made it impossible to speak or hear anything once we began the tour. No worries … Vladimir had covered the essential points during the presentation … and Irina was on hand to hold up informational placards to advise us of where we were and what we were seeing.
We were allowed to — in fact, encouraged to — take photos throughout the tour … with two exceptions. To comply with international regulations, no photography was allowed of (1) the reactor compartment, which we viewed through windows in the central maintenance room; and (2) the state-of-the-art central control room, which we were allowed to enter for an up-close-look at the wall-to-wall equipment used to monitor the reactors and other machinery essential to the operation of the ship.
This post is going to consist of some of the points covered by Vladimir in the conference room — in no specific order — with series of photos from the tour interspersed throughout. For additional information about the nuclear power plant, click here for information from the RosAtomFlot website.

Steering Gear Compartment |
- Keel laid in October 1989 at the Baltic Shipyards in Leningrad; construction completed in 2006 … by then the city had reverted to its original name of St Petersburg; went into service in 2007.
- 160m long, 30m wide, 11m draft (525/98/36 feet); 23,439 registered tons; 75,000 horsepower.
- Top speed in open waters: 22 knots (25 mph/50kph); continuous speed through 2m thick ice: 2 knots (2.3 mph/3.7 kph).
- Main principle behind building nuclear-powered icebreakers: reliability — at least one back-up for every system; 2 reactors, 2 turbines, 6 electric engines, 3 propulsion motors, 3 propellers.
- Double-hulled; inner hull — 35mm (1.4 inches) thick at the bow and the stem; 55mm (2.17 inches) thick amidships; outer hull — 48 mm thick (1.9 inches) argon welded armor steel overlaid with 5-7mm (.2 to .3 inch) plating of stainless steel where the ship meets the ice (ice-belt); 4m (13 feet) wide ice-belt all the way around.
- Spoon-shaped bow has a 48cm (19-inch) thick cast iron prow.
- Can remain afloat even if two adjacent compartments are flooded.
- Large number of ballast tanks provide additional protection for the interior of the ship.
- Reactors engineered to withstand collision with another ship of similar type up to speeds of 15 knots (17 mph/28 kph).
- Reactor rods replaced every 5-7 years.
- Used nuclear fuel stored aboard a special holding vessel for 2 years; discharged and stored ashore at a special facility for another 3 years; then transported to a plant in the Urals for recycling.
- Used reactor water kept in special tanks aboard the ship; discharged and stored in port.
- The amount of time the ship can remain at sea limited only by the food supply — usually 7 months when not in passenger service.
- Two desalination plants capable of generating 100 tons of fresh water daily; as of the time of the tour, still consuming what is left of the 680 tons of fresh water taken on in Murmansk on 1 July.
- 70 people work for the chief engineer; 3 watches of 4 hours each; 8 hours of rest. Education requirements: 5 years of university; 1 year of specialized training; refresher courses every 5 years.
- Use about 1 kilo (2.2 pounds) of uranium per reactor/per voyage; both reactors in operation at all times at approximately 25% capacity going through open water and 100% capacity in thick ice.
The tour was very interesting; I just wish they had been conducted in single groups of ten, instead of merging two groups for double that number. I can understand, however, the reason for combining groups — multiple tours daily would be a bigger burden on the crew of this working vessel. Also, the pace was necessarily fast, so I was unable to take detail shots and had to be satisfied with general ones.
Regardless, I am grateful we were given the opportunity to see the inner workings of 50 Let Pobedy. It really was fascinating to see all this.
