A giant artificial forest west of Odessa Remnants of anti-aircraft missile bases and WW2-era trenches can be seen. A walk around this forest is about 15km.

K-147 and K-438 were fitted with SOKS system in late 1970s; K-438 also featured an "Akula-style" sail after modernization.
The SOKS array position on K-438 was higher than that on K-147.

I heard a rumor a long time ago that "the algae-rich (or other plankton-rich) seawater in the three-coolant loop is beneficial for reactors during their first startup or after refueling" , or that "the algae content in the seawater affects reactor activity output (not referring to the risk of pipe blockage)."
This seems counterintuitive to me. Logically, PWR, unlike BWR, cooling water should receive very little radiation from the primary loop they absorb. Conversely, as long as algae don't clog pipes and machinery, they shouldn't theoretically affect the operation of the reactor.
I found this on Google Earth in Zviozdotchka in Severodvinsk. Judging from the aspect ratio, it appears to be an Akula. Its sail has been removed.
Next to it seems to be a submarine overhaul facility. Is it K391 or K295?
Furthermore, I also found a Victor (671RTMK?) near two typhoons.
Looking at photos of the 499P (2027 version) reminded me that prior to 2017, sidepods on LMP cars generally weren't visible from top-down view. Then, suddenly in 2017, the sidepods of TS050, 919, and R18 (which never raced) shifted to a design resembling the front section of Formula 1 sidepods; the R18 and TS050 even adopted the "coke-bottle" shape, a trend that persists today.
I looked up more photos and noticed that the intakes on early 2010s cars like the R18 and 908 don't seem significantly different from those on modern LMDh&LMP cars; rather, it appears they were intentionally coverd by bodywork, only the front diffuser outlet's turning vanes visible from the side and above.
Oreca 07 (2017) removed turn vane
Was this a regulatory requirement? Or are there specific aerodynamic advantages that lead manufacturers like Ferrari(until 2026) BMW Alpine to use hidden sidepod intakes instead of the exaggerated "Formula-style" intakes seen on the Porsche 963?

I watched a video of a nuclear power plant's PWR refueling, it's vessel is installed at the bottom of a large pool. During refueling, it's filled with water to shield radiation.
Considering the small space inside the reactor compartment, how would the same scenario be handled on a nuclear-powered ship? Filling the reactor compartment with water seems unacceptable. Would the entire vessel be moved out of the submarine and refueled in a dedicated workshop? Or would a robotic arm be used throughout the process?
This mummy seems quite unique. Is there any more information about her? Was she well preserved?

If Google Translate is correct, this is may what the OK650 (VM-11?)series reactor looks like.

Does it have a common name?
I didn't see this part in the official 3D model. Some youtubers' rule box models have a box in this place.
Judging from photos of various teams, the rules seem to require it to be aerodynamically neutral, but there are exceptions like Red Bull. Or perhaps it's just a thin plate, like the iconic parts on side of the nose cone on the 2016 Audi R18. Will this part become more complex in the future?
This test took place near Yasny ,Orenburg region, the site of last year's accident, should using a Dnepr rocket silo (in Yasny, Dnepr rocket only used two silos).
Sarmat's first-stage tank appears to be longer, while the second-stage tank is smaller (considering the angle, the difference is still significant).
The layout of the Sarmat's interstage and second-stage may differ from the R-36Ms (a new second-stage engine was used? The sarmat's interstage has no openings, while R-36Ms normally has four openings.).
The fuel tank manufacturing process is different (refer to R-36M2 in Ukraine rocket museum and "combat approved" TV show ).
Sarmat has FOBS capability (hello ,R-36orb).
A new gray coating was used, but the fairing was not coated with this layer (the fairings of Russia's current Topol-M series and Sarmat seem to lack this coating You can see a texture similar to carbon fiber).
The command center footage used by TASS is likely from a training facility in RVSN's Military Academy.
It consists of three 130-meter-high concrete towers and was completed in 1922.
The tower used to have a triangular metal structure at the top, which was removed after its retirement.

I consulted Wikipedia. Similar to the Soviet Annushka and Hanford Sites, these LWGR reactors used river water for cooling, so their process tubes were not pressurized, allowing uranium fuel to be added to the reactor at any time.
Later, the situation changed. The Soviet EI-2 ADE series reactors could used steam for power generation, but I didn't find the fuel reloading machines used in the reactor halls, similar to that used in the RBMK reactors; there were only simple cranes. How did they change fuels?
The RBMK fuel reloading machines' chambers appear to be pressurized, and after connecting to the process tubes, they change fuel like a revolver, without requiring reactor shutdown.
Do ADE and EI-2 only using valves or similar structures to isolate the process tubes preparing for refueling from the operating reactor?
I found this picture on a blog by Russians visiting it. It appears to be the interior of the DON2N radar transmitter (the square antenna to the right of the circular antenna).
Does each box represent a transmitting antenna, or does each box "drive" multiple antennas like a mini-led display(a led backlight bulb "drive" multiple pixels)?
The Untold Story of China's Nuclear Weapon Development and Testing
It seems to contain a large amount of information from Chinese sources. Can anyone fact-check it? Or are there any works on similar themes?
I bought this band around early 2024. Besides the nylon band, it's the one I wear most often, to the point that I can feel some wear on the parts that touch my skin. The color flakes became more pronounced with use like the rocks exposed by the tide on the coast.. A few days ago, I noticed a crack of about 1 mm appeared on it.; it seems the color flakes design make the band become alittle more fragile.
Compared to the currently available Veiled Grey, I much prefer its rich color flake design. I should have bought one earlier!
Are both the silver and green structures waveguides?
