The buildings
The plant is built one building at a time. This release has the whole plant site, the containment and shield building (in cutaway), the turbine building and the 500 kV and 230 kV switchyard. Each opens in 3D with linked drawings, a guided tour and a safety view.
Open the trainerThe whole plant at once: the nuclear island, the turbine building, the switchyard and the cooling tower, with the support buildings, tanks, roads and the river intake around them. Turn on X-ray to see inside the containment and turbine building. Each building also has its own tab with more detail.
Reactor and passive safetyContainment and shield buildingThe heart of the plant. Inside the concrete shield building, a steel containment vessel holds the reactor, two steam generators, four canned-motor pumps and the pressurizer, plus the tanks and valves that cool the core and the containment with gravity and natural circulation instead of pumps and AC power. Open in cutaway: the near half is cut away so you can see in.
Turbine-generator and feedwaterTurbine buildingWhere the steam does its work. One high-pressure and three low-pressure turbines spin a 1,375 MVA generator at 1,800 rpm. Below them, the condenser turns the exhaust back to water, and the heaters, deaerator and feedwater pumps send it back to the steam generators. Turn on X-ray to hide the walls and roof.
500 / 230 kVSwitchyard and offsite powerWhere the plant meets the grid. The generator's power goes up through a bank of three single-phase step-up transformers into a 500 kV breaker-and-a-half yard and out on three lines. The same connection, and a separate 230 kV reserve line, bring power back in to run the plant.
