Atomic energy as well as atomic power plants themselves are undoubtedly hot issues today. This post is going to be about the Kola APS, its structure and operating priciple.

The basic operating principle of an atomic power station is very simple: a power station has two contours both filled with water. The first contour is radioactive. It consists of VVER-440 reactor, a volume compensator, a main circulating pump and 6 circulating loops. In the second contour there is a steam generator, turbines, an electro generator, a condenser and condensing pumps. This contour is not radioactive.

The reactor of the Kola atomic power station is water-moderated. It works on thermal neutrons. Desalinated water serves as a heat-carrier – it takes heat away from the active zone of the reactor. Thermal capacity of one reactor is 1375 MW which makes up 440 MW of electricity.

And this is a mockup of a fuel element.

These fuel elements made of zirconium contain uranium-235 in tabloid form. Tubes are collected in fuel assemblages of decagonal form. Assemblages with nuclear fuel are located in the active zone. There goes an operated chain reaction which heats the distilled water of the first contour to 572 F. To avoid boiling in a contour high pressure is retained. With the help of circulating pumps water goes to the steam generator.

The steam generator is a place where heat exchange between water of the first and second contours proceeds. Water of the second contour passes from one modular condition to another – steam, and water of the first contour goes back to the reactor.

Steam formed in the second contour rotates the turbine connected with the electro generator with high speed. The electric power goes to the transformer and then, via transmission line to consumers while the steam of the second contour turns to water again and goes back to the steam generator.

An amusing thing – there is life buoy fixed on the car which pulls out cores from the reactor.

To leave the reactor room you have to pass a radiation check.

    • F. Bunker here.

      Oh come on guys, nuke plants are cute and a great soviet invention…but only asians are stu/pid enough to build one in a earthquake risk region.

      • I would argue that they are an American invention, even though the Soviets built the first civilian power plant. But yes they are a great invention. The safest form of generating electricity.

  1. I have a cousin who works at a nuclear power station in Arizona. He seems to like it well enough, he’s been there forever it seems. They keep busy checking to see everything is as it should be.

    I don’t think it would be boring once you understood what everything on that control board is for and how it all works.

  2. Guy in the pic captioned “Nuclear waste disposal center.” : Wasn’t he the dude serving Karl “french fried tators” in Sling Blade?

  3. The location at the bottom of the post points to some backyard in the Polyarnye Zori town. The actual location is a few miles to the north:

  4. Very interesting article. And the explanations to the pictures are also better than most of the times. Thank you
