  • People in Ontario, Canada woke up to the public alert about an accident on Pickering nuclear plant. It said there was no leak but public within 10km should remain alert.


    The radio is saying the alert was sent out by mistake. They don't say whether an incident actually occurred, however..

  • From Rob Woudenberg 's link above...


    Additionally, there’s also low-energy nuclear reactions (LENR), which we’re working on here. We’ve got 22 years and hundreds of experiments now on low-energy nuclear reactions which indicate that this is real. Plus, we now have a theory that indicates that it’s condensed-matter nuclear physics.

    So LENR appears to be collective effects, not particle physics. It seems that you can get around Coloumb barrier by forming ultra weak neutrons using heavy electrons. This not only enables you to form the neutrons, but also convert the gamma radiation from beta-decay into thermal energy so that you don’t need as much radiation protection. LENR is expected to be anywhere from 20,000 to 3 million times chemical efficiency, and if we can get that in place it will truly revolutionize space. 1*URxRnxUmK7KRckCC5JoRdA.png The VASIMR is a high-thrust magnetohydrodynamic engine for spaceflight.

    I didn’t realize the LENR was being investigated that heavily by NASA.

    Well, it’s not heavily, I mean we have a $200,000 to $300,000 a year effort. We’re also cooperating with people on this, but I can’t divulge details under cooperative agreements.

    LENR purportedly also produces transmutations, which is quite interesting. For in-situ resource utilization, if LENR works, perhaps we can take elements on the planet and possibly transmute them into something we need.

    What about something like the IEC Polywell reactor that Dr Robert Bussard was working on for the Navy? Is that worth pursuing?

    Yeah, I’m very familiar with the Bussard stuff. That’s aneutronic fusion, using pB¹¹ or D-³He, and it may be possible. It’s yet another of five or six very advanced energetics technologies that we need to study more heavily than we are now.

    I just read about the 100 Year Starship program, so hearing you discuss MHD, LENR, anti-matter and other advanced propulsion makes me wonder if NASA isn’t going back to the drawing board in some ways.

    Well, if you look at space access, it’s essentially done today the way it was done in the ’50s. These are basically ICBMs — modernized versions of German V2 rockets. It’s chemical propulsion, and we’re out at the ragged edge of the performance of chemical rockets. We need something a lot better than that if we’re going to make spaceflight safe and affordable.

    What we’ve realized at NASA is that if you’re going to do safe and affordable manned space exploration, then you’re going to need another whole level, another whole generation of the technology.

    Back in the Bush-era space program when 100 YSS was launched, this vision was put in place with essentially conventional technology. Over the years and in many, many projects, NASA has warned that if you want revolutionary goals like humans in deep space you need revolutionary technologies. These aren’t cheap to develop, and we had to divert resources into developing them, which we’re doing.

    Researcher is another French guy, intense light pulses and management/cleaning of waste in shorter times! Must have some relation to what happens in some condensed matter reaction experiments. Also shows how the reaction doesn't have to be nuclear to stimulate a stabilisation, though certainly doesnt hurt if it is! Just needs intense light pulses or some electromagnetic fluctuations to flick the atom to decay into a more life friendly state. Absorb the research, helps me to support my Hope and Belief there is something mindblowingly practical talked about on this website! A partner to processing for a MSR plant at least.

  • Signals from inside the Earth: Borexino experiment releases new data on geoneutrinos

    a Borexino Collaboration


    Scientists involved in the Borexino collaboration have presented new results for the measurement of neutrinos originating from the interior of the Earth. The elusive "ghost particles" rarely interact with matter, making their detection difficult. With this update, the researchers have now been able to access 53 events—almost twice as many as in the previous analysis of the data from the Borexino detector, which is located 1,400 metres below the Earth's surface in the Gran Sasso massif near Rome. The results provide an exclusive insight into processes and conditions in the earth's interior that remain puzzling to this day.

    The earth is shining, even if it is not at all visible to the naked eye. The reason for this is geoneutrinos, which are produced in radioactive decay processes in the interior of the Earth. Every second, about one million of these elusive particles penetrate every square centimetre of our planet's surface.

    The Borexino detector, located in the world's largest underground laboratory, the Laboratori Nazionali del Gran Sasso in Italy, is one of the few detectors in the world capable of observing these ghostly particles. Researchers have been using it to collect data on neutrinos since 2007, i.e. for over ten years. By 2019, they were able to register twice as many events as at the time of the last analysis in 2015—and reduce the uncertainty of the measurements from 27 to 18 percent, which is also due to new analysis methods.

    "Geoneutrinos are the only direct traces of the radioactive decay that occur inside the Earth, and which produce an as yet unknown portion of the energy driving all the dynamics of our planet," explains Livia Ludhova, one of the two current scientific coordinators of Borexino and head of the neutrino group at the Nuclear Physics Institute (IKP) at Forschungszentrum Jülich.

    The researchers in the Borexino collaboration have extracted, with an improved statistical significance, the signal of geoneutrinos coming from the Earth's mantle which lies below the Earth crust by exploiting the well-known contribution from the Earth's uppermost mantle and crust—the so called lithosphere.

    The intense magnetic field, the unceasing volcanic activity, the movement of the tectonic plates, and mantle convection: The conditions inside the Earth are in many ways unique in the entire solar system. Scientists have been discussing the question of where the Earth's internal heat comes from for over 200 years.

    "The hypothesis that there is no longer any radioactivity at depth in the mantle can now be excluded at the 99% confidence level for the first time. This makes it possible to establish lower limits for uranium and thorium abundances in the Earth's mantle," says Livia Ludhova.

  • ZenoOfElea - Very relevant indeed. I like this...


    'In their paper in ACS Central Science, the Leiden physics-chemistry cooperation charts the mound evolution atom by atom. Starting out with an initially flat platinum surface in a solution of perchloric acid (HClO4) in water, they oxidized and reduced the platinum 170 times, by varying the electrical potential over the surface, while imaging the characteristic pockmarks caused by the mounds. By measuring the electrochemical current, and connecting that to the images, the researchers could specify the contributions of different features of the crystal plane.

    But the exact shape and size of the mounds could only be explained after a conceptual leap. It is not only adatoms that can wander around, but vacancies can do the exact same thing. An atom next to the vacancy moves over to fill it, and thus the vacancy has moved one atom. Similarly, vacancies can meet other vacancies to cling together. Just as adatoms form islands, vacancies can cling together to form growing holes.'
