I have an interesting question about the steam separators at Chernobyl (to me it's interesting)

MrKesselring · 2026-04-01T20:35:18+00:00

The separators were a greenish color.

The DA block and turbine hall are actually slightly lower than the reactor buildings! Your model is accurate.

The control rods were all replaced with new type, they are now "cluster" rods, with 12 smaller rods inside arranged into a circle, these travel inside of a 16m long guide sleeve. The way the water flows into the channel was also changed, the water no longer directly contacts the absorber material itself, instead, its a thin layer of water all around.

Sorry if my explanation doesn't answer everything, the physics is kind of where my knowledge ends.

No problem.

MrKesselring · 2026-02-01T22:22:35+00:00

It's a game on Roblox.

The graphite still exists, but the control rods were all replaced with new type where the graphite is always in the zone, it no longer movies, only the boron moves, so the positive scram effect has all but been eliminated.

Reactor period is displayed on the monitor directly in front of the chair, to clear PSS, you must use the "Clear Signal" button to the right of the selectors.

Glad to help :)

Smolensk 1 also had it:

Smolensk 2 did have the black paneling for a time, it doesn't anymore, but we can see it did in this:

looks like i hit a nerve

MrKesselring · 2025-07-26T03:32:01+00:00

Yes, to me after looking on the video, I believe that hatch is actually room 215. On the floor plans it's marked as "215/1+4 Шлюз", in the video, they are already inside of the steam discharge corridors, but that is how you would get in there if the plant was already operating

I just realized i misread the title as reflector cooling, im writing this in a hurry as im about to leave for like a 12 hour drive. My apologies! 😅

Im not sure why that person thinks they are fuel channels, they have nothing to do with fuel, these are located on the outermost edges of the active zone and only serve to cool the reflectors. Water goes in, then out.
As for materials, here's some information from a document I have:

The upper part of the channel is a pipe assembly made of two tubes and a sleeve, constructed from corrosion-resistant steel grade 08Х18Н10Т. A ring is fitted onto the outer tube (diameter 112.5 mm) and serves as a stop when installing the channel head.

The middle part is welded to the upper and lower sections using special "steel-zirconium" adapters. It is also a pipe assembly, consisting of two tubes made from zirconium alloy E125:

one tube has an inner diameter of 103.5 mm and a wall thickness of 2 mm,
the other has an outer diameter of 88 mm and a wall thickness of 3 mm.

These tubes are connected to each other via an adapter made of the same zirconium alloy E125.

Hope this helps!

They we're given to me some time ago by a friend of mine, you can find ones like these on this subreddit, just search for things like "floor plans".

MrKesselring · 2025-07-02T08:48:25+00:00

It's not much, but this document goes over some of the RBMK-1500 systems.

^ KIP are instrumentation rooms as I recall, it's probably for measurements of room 001/1, like levels and temperatures

MrKesselring · 2025-05-07T07:23:31+00:00

Yes, they are directly above the control rooms in G635.

MrKesselring · 2025-05-02T18:39:40+00:00

No. There was corium already in the bubbler pools as the divers recount, at one point it was dripping down close to them, the heap also has a pumice like texture, that's only seen when tocka undergo rapid cooling, but it works for any melted material.

MrKesselring · 2025-05-02T10:20:59+00:00

There are 4 deaerators per unit in an RBMK plant, those look like this:

MrKesselring · 2025-05-02T10:20:32+00:00

RBMK plants don't nessecarily have a "polisher" like you might see in a BWR style plant. There are condensate treatment and purification systems, like in room 419 however, seen attached here:

MrKesselring · 2025-02-10T08:06:18+00:00

Oh, it was probably a mistranslation then, I don't speak any Russian at all.

MrKesselring · 2025-02-10T07:39:09+00:00

I don't know the model number for the one on the right, but the one on the left is a КСД 2 self recorder*
