"A spike in background radiation was recorded in the nearby city of Severodvinsk in the Arkhangelsk region"

Boy - that's BAD - most Russians who live/work up that way won't go near the place as is unless they absolutely have to - lots of Russian jokes about "glowing in the dark" on a normal day............. like Severomorsk near Murmansk..................

Not sure if these are current pictures but claimed to be some.

“The only known weapon systems with nuclear propulsion under development and testing are the Poseidon underwater drone and the Burevestnik cruise missile. Nyonoksa is located 25 kilometers west of Severodvinsk in Arkhangelsk region. The test site was established in 1965 and are mainly engaged in testing prototypes of different submarine missiles.”

‘weapon with nuclear propulsion’?

ORAC 9th Aug 2019 10:16


Weapon with nuclear propulsion?
The nuclear leak is puzzling. I can’t see a missile being tested with a fitted nuclear warhead, which would imply that either it was a missile with a direct nuclear drive (SSC-X-9 Skyfall) or a test launch from onboard a vessel where the reactor was breached. However the Skyfall test site is at Pankovo, nowhere near the accident site. So I doubt if a nuclear engine was involved, more likely an onboard ship/sub explosion which causes a rupture of the reactor and release of radiation before it was scrammed and contained.

Soviet Experimentation with Nuclear Powered Bombers

substitute oil for ammo and we are into the start of red storm rising. ..��

Going back to the Montgomery .. I think the big worry there now, is when the hull finally breaks up its quite a lively tide, and all that stuff is going to start washing up on both side of the estuary .. Probably better the bury the whole lot in a few billion tons of concrete and put an airport on it..

The Moscow Times seems to be more neutral and balanced in their reporting of the suspected nuclear-powered missile’s liquid launch-propellant explosion.

Seven people dead is the latest count unfortunately. Two military and five from nuclear authority Rosatom.

I assume gents here understand the difference between an isotope power source, reactor and N-warhead.
Seems to be a conventional tragic accident with liquid propulsion stage of a missile...
Radiation level around the site is normal, and it would be difficult to hide if it were not true: local greens and "liberals" would start crying all over RuNet.

This map seems to indicate some spike recently:

https://thebarentsobserver.com/en/se...-after-missile

While normal background in the town with a population of 190,000 is around 0.11 µSv/h (microsivert per hour), the levels measured at the monitor on the Lomonosov Street near Lake Teatralnoye peaked at 2 µSv/h, nearly 20 times higher gamma radiation than normal. That, though, is still way within permissible levels for population exposure.

https://thebarentsobserver.com/sites...verodvinsk.jpgThis map shows the maximum levels of radiation at the public monitors in Severodvinsk around noon on August 8th. Map by the Arkhangelsk branch of Ministry of Emergency Situations (EMERCOM).

Radiation increase peaked between 11.50 and 12.30 local time and was back at normal levels at all location by 14.00, head of the Civil Protection Department of the administration in Severodvinsk, Valentin Megomedov, told regional news agency in Arkhangelsk 29.ru on Thursday.

“The Burevestnik missile is equipped with a small nuclear reactor.If the missile fuel that exploded at Nenoksa site happened while testing a nuclear-powered cruise missile which uses a propellant engine in the start, radioactivity could have been released from possible damages of the small reactor.”

The administration has now deleted its statement online about the spike. The BBC asked officials there why, and they said "because this incident comes under the authority of the defence ministry".

Nothing to see here, move along, there is no problem with the Chernobyl reactor.

Do the Russians actually believe anybody believes a word they say?

Or is the western world so weak that we can't hold them to account for any of their actions in the Crimea, Syria, Iran, CAR?

What is an isotope powered liquid fuelled rocket engine? Not a nuclear direct cycle engine in a cruise missile - unless they mean a booster rocket used to launch and get the missile up to cruise speed before being discarded and the nuclear jet engine taking over?

In which case the booster explosion would have wrecked the jet engine and scattered the nuclear pebble bed around the local area? In which case there will be a wide area of heavy surface contamination.

https://www.theguardian.com/world/20...test-explosion

Russia’s nuclear energy agency has said an explosion that caused radiation levels to spike in the Arkhangelsk region was caused by an accident during a test of an “isotope power source for a liquid-fuelled rocket engine”.

In a statement released late on Friday, Rosatom said five of its employees had died as a result of the accident and three more were being treated for burns. The statement was the first confirmation that the agency was involved in the incident, which briefly drove radiation levels up to 20 times their normal levels in the nearby city of Severodvinsk.

Rosatom’s description of the incident could indicate it was testing the nuclear-powered cruise missile Burevestnik mentioned during a speech by Vladimir Putin last year.

Russia’s ministry of defence first confirmed the explosion on Thursday, saying two people had been killed and six injured in a botched test of a liquid-fueled rocket engine. The injured included ministry employees and civilian contractors. Rosatom’s statement may indicate that three of those first reported as injured had since died. Despite reports that the wounded had been transported to Moscow for medical care, neither their names nor locations had been confirmed.......

Nuclear energy for propulsion? That's quite a different idea to nukes like the Kiwi series, used in satellites or nuclear warheads.
What the heck are they producing that uses a nuclear engine?

Kinda reminds me of Project Pluto- and that was off the wrong end of the scariness scale.
