    Ignition does not require any battery on a scale that would cause a fire or even the "small" amount of radiation released.
    All it takes is a single tiny spark. So this theory is not credible. Keeping things dry and functional does not require active
    power but hermetic seals. The seabed "SLBM" concept is wonky.

    Given the profile of the isotope fallout, the test involved something more than a nuclear battery or spark generator.

    Yes, a tiny spark. Dozens of times. And you still need a battery to deliver the energy for that.

    Search the article in english and read it.

    Articles are misinformation when it comes to top secret military projects.

    Where do you get the notion that rockets require continuous ignition? I won't bother asking for citations since what you say
    is simple nonsense. We are not talking about orbital maneuvering thrusters. Gravity acts continuously so no ballistic missile
    turns off its motors and burns through its fuel stock basically as fast as it can.

    A single detonation spark can be produced by a microgram or smaller isotope particle housed in a metal container measuring
    hundreds of a millimeter. Such a microscopic spark source is clearly reusable. If you plan to have it sitting around for
    several isotope half-lives (i.e. decades) you need to scale up this microscopic battery but it will never reach a size to
    produce measurable fallout in case of fire or explosion of the rocket.

    Whatever article you read is spewing obvious nonsense.

    BTW, the technology of small fluid driven turbines is not developed and is not deployed anywhere even though nuclear power plants
    are old news. The accident in question did not involve an isotope battery and it did not have anything to do with some
    ridiculous spark generator. Scaling a nuclear reactor to the isotope battery scale is not a trivial task. At the size of
    an isotope battery it is likely that some hybrid variant emerges which is neither a full blown nuclear reactor burning
    enriched uranium or MOX and not an simple isotope decay device.

    US intel report says mysterious Russian explosion was triggered by recovery mission of nuclear-powered missile, not a test

    A U.S. intelligence report says the mysterious explosion off Russia’s northern coast occurred during a recovery mission to salvage the Kremlin’s nuclear-powered missile from the ocean floor.

    The mysterious explosion sparked fears that Russia had tested its nuclear-powered Burevestnik missile, also known as Skyfall.

    CNBC learned last year of similar plans Moscow made to try to recover a nuclear-powered missile lost at sea.

    WASHINGTON — A U.S. intelligence assessment found that the mysterious explosion off of Russia’s northern coast occurred during a recovery mission to salvage a nuclear-powered missile from the ocean floor, according to people with direct knowledge of the report.

    The mysterious explosion on Aug. 8 killed five scientists and sparked fears that Russia had tested its new nuclear-powered Burevestnik missile, also known as Skyfall.

    “This was not a new launch of the weapon, instead it was a recovery mission to salvage a lost missile from a previous test,” said a person with direct knowledge of the U.S. intelligence assessment. “There was an explosion on one of the vessels involved in the recovery and that caused a reaction in the missile’s nuclear core which lead to the radiation leak,” said another person, who spoke to CNBC on the condition of anonymity.

    The U.S. intelligence report did not mention potential health or environmental risks posed by damage to the missile’s nuclear reactor.

    Makes no sense.

    First thing they would be doing with flying prototype of something like this would be to install landing gear

    Who the hell would want to chase nuclear device across the Arctic instead of landing it on the runway?

    Not to mention that whole thing would have disintegrated on impact with water surface and/or ice

    Total Bullshit.

    The Burevestnik engine is essentially a ramjet wher the air is heated by a nuclear reactor rather than combustion of a fuel. Follwoing burnout (and ejection?) of its solid boosters, there are no combustibles onboard, so no source of explosion. Reactor malfunction might cause it to overheat (and maybe even meltdown) but explode? No, not gonna happen.

    This is simply a pack of stupid lies from the Pentagram and their enablers in corporate lamestream media.

    And once things go underwater they can become rather hard to find.

    Equally when hit at speed water is no softer than rock so why bother?

    Of course the US traditionally landed their spacecraft in water so they wouldn't appreciate the error.

    The Burevestnik engine is essentially a ramjet wher the air is heated by a nuclear reactor rather than combustion of a fuel.  Follwoing burnout (and ejection?) of its solid boosters, there are no combustibles onboard, so no source of explosion.  Reactor malfunction might cause it to overheat (and maybe even meltdown) but explode?  No, not gonna happen.

    This is simply a pack of stupid lies from the Pentagram and their enablers in corporate lamestream media.

    The ramjet/scramjet aspect is likely 100% correct. It would also produce a hot exhaust which would look like flame at some angles.
    Russian developers must have achieve power densities from the "nuclear battery" in excess of fuel allowing a total replacement.
    This is a rather spectacular technological achievement. But I am certain it is not based around an isotope generator so all the talk
    about electrical turbines and Cs-137 is BS diversion.

    A nuclear reactor cannot be scaled arbitrarily since the neutron flux does not vary in a manner to compensate for the scale. Small
    reactors generate fewer neutrons so it becomes nonlinearly more difficult to sustain nuclear reactions at small volumes. Obviously,
    isotope generators do not have this issue since all they do is exploit some decaying isotope and deplete with time. In order to drive
    a ramjet via air heating, this approach cannot be used since it is not indefinite by construction. So a small species of nuclear reactor
    with actual nuclear reactions needed to be developed. Nobody can fob off Russian science as second rate. It is world leading.

    I suspect that the neutron flux density problem is addressed by increasing the energy of the neutrons. So this small reactor is a
    type of breeder reactor with a harder neutron energy spectrum.

    Do you think that Scott Ritter got it right in calling this a test of a RTG for powering the electrics and command electronics of seabed-installed missile canisters? The RTG apparently tested OK but the missile somehow leaked propellents and an explosion resulted.

    The size of a "nuclear battery" for such tasks can be very small. So the amount of radiation released would be tiny and blow detection
    thresholds of instruments that registered a radiation spike (small one) for half an hour. I don't think Ritter thought the fallout aspect through
    enough.

    Also, to me it looks like the explosion was all about the "nuclear battery" since a missile's propellant blowing up would have incinerated the
    floating platform. Everybody in proximity would have died quickly. Even the people blown into the water would have experienced heavy
    burns and likely drowned. They managed to save some of the people thrown into the water. From what I can tell the burns are radiation
    burns. This ain't no isotope generator. Rocket and missile accidents are very ugly.

    We are in a new area of technology and applied science with the nuclear reactor being developed. I am not surprised that they had such an
    accident since they do not have a perfectly working model living inside a computer. The problem is that they were too sloppy with handling
    this device. There should have been no people exposed to danger until some metrics of the reactor were determined. That is, they needed
    to monitor at the very least its heat generation continuously. Neutron flux monitors should have been installed as well. I guess the Soviet
    era sloppiness has not worked itself out of the culture...

    One of the two Project 114 lighters from LASH Sevmorput beached after what was likely a failed attempt at recovering the reactor of a 9M730 Burevestnik missile; note container in Rosatom corporate blue; radiation from where this was shot is 750 µR/h

    Russian nuclear missile with ‘unlimited’ range to be ready by 2025, US intelligence says

    KEY POINTS
    Russia’s nuclear-powered missile with so-called unlimited range will be ready for war within the next six years, a slightly accelerated timeline than previously reported, according to a U.S. intelligence assessment.

    The revelation of the new, more ambitious timeline for the missile comes even though the Kremlin has yet to secure a successful test over multiple attempts, according to sources with knowledge of a U.S. intelligence report.

    The rest is all the same

    Sitting in the launch tube of a SSBN for 20 years. Which ist like sitting in the ocean depths. Even less need for maintenance then with previous missiles.

    SLBMs don't need an independent long-life power source - they have the submarines power grid to draw upon. Most likely this RTG-like device (if thats in fact what it is) would intended for containerised missiles installed to seabed without any connections to energy infrastructure.

    I mean when attacked by Saudi and Pakistani nationals during 11/9, the US invaded Afghanistan and Iraq, and eventually got their man... in Pakistan.

    Wouldn't believe US Intel if they said up was up and down was down.
