Correction: not necessary Burevestneg, any craft with nuke propulsion.

Maybe it didn't fall, but couldn't surface.

Sutton claims Sarov, currently the only Poseidon carrier, was out at sea in June.

No-one in the right mind would come close to... oh

Soon.

The jist: Burevestnik is too long to fit into those 20-foot containers, so they'd have to partly dismantle it right there.

Apologies for derailing post.

The god emperor of all mankind, without a doubt

The emperor of course. Not that I'd like, but everything else is heresy :-)

Seriously though, there is one thing I don't understand. If this was really open cycle nuclear thermal propulsion, wouldn't successful test firing be even less inconspicuous then failure?

Therein lies the rub. Open cycle is hardly required. Here's a scheme for four engines fed by one reactor:

Yes, but that aircraft is manned. Crew is certainly a good reason to bother with complexity of closed loop. So, was this "Burevestnik" crewed? Or are there other reasons for unmanned misile to go for closed cycle?

Depends; the claims that Poseidon torpedoes have a tactical anti-ship application make me suspect that not all Burevestniks may turn out to be missiles. The idea of a nuclear Global Hawk had been entertained previously.

Actually, it's not a factor in closed versus open loop. This only affects the exhaust, which generally goes behind the aircraft, while the crew sits in the front. Closed loop is generally safer for people on the ground, which is an important concern with both manned and unmanned aircraft. That said, I'm not sure if open cycle nuclear jet is really as much of a radiation hazard as they claim. There might be other, more complicated engineering reasons to go with closed cycle, though.

It is also the only real way to power propellers with a nuclear reactor. In some flight regimes, this might actually be superior to jet engines.

And when it's not, the kerosene injectors kick in.

Something in Russian on nuka-cruise-missile topic. Not sure how much relevant.

Somebody at least bothered with the math.

Ot's also quite interesting that tad-hardened electronics have been a noticeable vulnerability of the Russian space industry.

Rosatom found a contractor who's going to tow the barges to the nuclear submarine disposal site at Saida-Guba.

(A little offtopic)

The radiation spike up to 0.3 mkSv/h on this Tuesday  _{("today" or "last"? it's Tuesday now)} in Severodvinsk, previously reported by the city administration, was actually caused by a serviced sensor malfunction.

Currently all is normal, 0.11..0.14 mkSv/h.
