VT Nuclear Education: LENR Neutron Distribution




Neutron energy distribution ranges for Low Energy Nuclear Reactions in Deuterium. Cold Fusion / Fission Velocities.

… by  Jeff Smith


NASA Cold Fusion Project

NASA Cold Fusion Project

In the cold Fission or Fusion process, the key element in it’s successful operation involves the velocity of the Neutrons used in creating the low energy nuclear reactions.

If the velocity of the neutrons is to fast or too slow, the nuclear chain reaction will fail and it will not be efficient enough to produce excess energy from either the splitting or fusing of the nuclear fuel used, usually Uranium or Deuterium.

For fusion, it is usually a form of deuterium either in a liquid or gas form. In Low energy nuclear reaction fission, usually a form of uranium in liquid form is used. The first very low powered nuclear reactors used uranium dissolved in a liquid form. However it was determined that any form of uranium in a liquid form greater than one pound or two would form a critical mass limiting its effective size to very small reactor designs.

But for very small low powered reactors that produce less than 50KW to 100KW thermal; this is the easiest  form of Low Energy Nuclear Reaction to go with, as currently undergoing development in Japan for mass commercial marketing world wide.

Cold Fission is much easier to produce than cold Fusion. A very small amount of uranium, about 3 grams, dissolved in sulfuric battery acid will produce a small continuous nuclear chain reaction for years simply by using the Townsend electron avalanche process to trigger and drive a low level neutron chain reaction.

The chain reaction can easily be controlled electrically and is safe. Thermal cut off switches can be added as a safety device. By simply turning off the electrical power to the fuel cell it will shut down on its own (scram). No China syndrome to worry about or run away chain reaction to deal with.

The Uranium fuel is cheaper than Deuterium and will last for years. This is a much better concept than using Deuterium due to its high cost per kilowatt output. The other problem with using Deuterium or heavy water as a fuel is that it simply boils away and you cannot recover it.

Watt per watt, gasoline or diesel fuel is much cheaper to use per kilowatt of energy produced. Cold Fusion is a loser compared to a Low level nuclear chain reaction device (Fission Reactor).

Very small fission reactors don’t have all of the problems and complexities of its bigger brothers. They are safe, simple, cheep and clean with no moving parts or control rods to deal with.

Using one as a nuclear heat source to drive a simple Sterling heat engine is already under way in both Germany and Norway with their Dolphin submarines. The US Navy already uses a low energy liquid fuel nuclear reactor to drive their stealth mini subs. (which don’t exist)

In cold fusion, the Deuterium fuel known as heavy water is forced by electron current flow into the center electrode and magnetically compressed producing  low energy nuclear fusion (the Townsend electron avalanche process) so we are told. The problem with this scheme is three fold.

  • One; The voltage and current requirements are all wrong based on the required velocity of the neutrons in order to form a fusion event and
  • Two; The center electrode would have to be made of Cadmium in order to absorb all of the incoming neutrons and properly compress them by low level magnetic fusion confinement.
  • Third; If the fuel cell is used in the neutron resonance capture mode then the applied electrical charge would have to be pulsating DC operating at the correct resonate frequency.


Fission chain reaction

Ponds, Fleishmann and Jones all used less than 33 volts DC, the minimum voltage that can be used to properly electrolyze Deuterium or heavy water.

They also used a palladium electrode. The Palladium electrode requires a much higher electron voltage level in order to create a catalytic reaction in Deuterium. No pulsating DC is used, therefore the neutron resonance mode can’t be used with a palladium electrode only cadmium works at this voltage level.

In both Pond’s, Fleishmann’s and Jones’ theories, the mechanisms of operation and lab results never added up to a working model, basically all bad science. This is why all so called cold fusion experiments are nothing but very expensive catalytic converters just like in your car exhaust system. See the below listed neutron velocity charts for further information on the subject matter.

The Japanese government spent over 50 million dollars and over 15 years on experimenting with cold fusion using the help of Jones, Ponds and Fleishmann without a single positive reaction that was provable. In the end they gave up resorting to designing cheaper low energy nuclear fission reactors based on liquid uranium as a fuel.

If SANDIA, Phillips, MBB, Daimler Benz, Toyota, Honda, Sony, and Fujitsu couldn’t get it to work after wasting over 100 million dollars on this then you know its a scam. How many very small personal low level nuclear reactors could you have built and run for that much money?

All cold fission that occurs with less than 300 volts applied is just simply a fancy catalytic converter. You can get more energy out of your car exhaust system than you can from one of Steven Jones cold fusion reactors.

A chart displaying the speed probability density functions of the speeds of a few noble gases at a temperature of 298.15 K (25 C). An explanation of the vertical axis label appears on the image page (click to see). Similar speed distributions are obtained for neutrons upon moderation.

Thermal neutrons

thermal neutron is a free neutron with a kinetic energy of about 0.025 eV (about 4.0×10−21 J or 2.4 MJ/kg, hence a speed of 2.2 km/s), which is the energy corresponding to the most probable velocity at a temperature of 290 K (17 °C or 62 °F).

After a number of collisions with nuclei in a medium (neutron moderator) at this temperature, neutrons arrive at about this energy level, provided that they are not absorbed.

Thermal neutrons have a different and often much larger effective neutron absorption cross-section for a given nuclide than fast neutrons, and can therefore often be absorbed more easily by an atomic nucleus, creating a heavier, often unstable isotope of the chemical element as a result (neutron activation).

Fast neutrons

fast neutron is a free neutron with a kinetic energy level close to 1 MeV (100 TJ/kg), hence a speed of 14,000 km/s, or higher. They are named fast neutrons to distinguish them from lower-energy thermal neutrons, and high-energy neutrons produced in cosmic showers or accelerators.

Fast neutrons are produced by nuclear processes:

Fast neutrons can be made into thermal neutrons via a process called moderation. This is done with a neutron moderator. In reactors, typically heavy waterlight water, or graphite are used to moderate neutrons.


Fast reactors and thermal reactors


Who will contol where mass application of nuclear power will go?

Who will contol where mass application of nuclear power will go?

Most fission reactors are thermal reactors that use a neutron moderator to slow down (“thermalize“) the neutrons produced by nuclear fission. Moderation substantially increases the fission cross section for fissile nuclei such as uranium-235 or plutonium-239.

In addition, uranium-238 has a much lower capture cross section for thermal neutrons, allowing more neutrons to cause fission of fissile nuclei and propagate the chain reaction, rather than being captured by 238U.

The combination of these effects allows light water reactors to use low-enriched uraniumHeavy water reactors and graphite-moderated reactors can even use natural uranium as these moderators have much lower neutron capture cross sections than light water.

An increase in fuel temperature also raises U-238’s thermal neutron absorption by Doppler broadening, providing negative feedback to help control the reactor. Also, when the moderator is also a circulating coolant (light water or heavy water), boiling of the coolant will reduce the moderator density and provide negative feedback (a negative void coefficient).

Intermediate-energy neutrons have poorer fission/capture ratios than either fast or thermal neutrons for most fuels. An exception is the uranium-233 of the thorium cycle, which has a good fission/capture ratio at all neutron energies.

Fast reactors use un-moderated fast neutrons to sustain the reaction and require the fuel to contain a higher concentration of fissile material relative to fertile material U-238. However, fast neutrons have a better fission/capture ratio for many nuclides, and each fast fission releases a larger number of neutrons, so a fast breeder reactor can potentially “breed” more fissile fuel than it consumes.

    There isa great need of some majoe update/correction of some fundamental scientific frauds, which were at the roots of our “modern times”. Feudalists, or should I better say “true british aristocrats” knew very well, how to bring this fradulent system of “natural sciences” into the world.

    Their methods were very sophisticated, though even many of their representatives were too dumb to understand “real science”. As Newton was a well known black magician at his time, together with so many other fraudsters like Bacon, Galilei, Descartes, even Voltaire, Bentham, Malthus, Darwin and so many others of those “enlightened freethinkers” in their aristicratic circles.

    The play was rigged from the beginning to a great extend and this went on rill today. Inbetween, there were some “disruptions”, done by scientists/engineers like Tesla, Franklin, Faraday, Maxwell and other geniusses. Beginning with the 20th century, we find the new phenomenon of science going “black” or hidden from the public as well as rewriting some fundamentals to distract from deeper insights in the nature of matter, space and time.

    Black magic like gravitation as all form of black energy and black matter should have been thrown in the waste basket long ago, because the true nature could have been found by correctly applying Maxwells laws in it’s full and correct forms. Einstein would never have any chance for his great media spectacle and fradulent “scientific revolution”.

    • Detlef Reimers  September 16, 2014 at 12:37 pm

      The real meaning of “german science” and his astounding dominance throughout the frist hlave of the past century was not to be “anti-jewish”, it really meant to be “not corrupted” – the rest was media propaganda. Therefore, especially as the project more and more touched deep nuclear former secrets, this also went black as did many of the really fundamental workings on early plasma physics, the relationsship between gravitation and magnetism and some deeper insights about quantum mechanics and effects in physics.

      This was all collected and brought to the US and the UDSSR after WWII. What the americans didn’t realized was the fact, that one of the most “enlightened one”, Manfred von Ardenne, slipped through their fingers and instead landed in Russia. This might have been one of the most important counter events, because he quasi knew about everything and he could invent new things that worked in series, totally astonishing up to this day. He hold something like 900 “real” patents.

      Lets go on and unearth those “gone black science” part by part, it’s long overdue. There is no such thing as “national interest in hiding real science”, it’s – in itself – a total fraud and a real crime and threat against humanity. Only think about the medical “science” then and now, and you know why.

    • Jack Heart  September 16, 2014 at 2:05 pm

      If von Ardenne had ended up here Detlef the human race would have ceased to exist before 1950. He knew that, so did Hitler and Bormann. As it is now the whole world ought to praying to their plastic Jesus that Mr. Duff and company stay healthy.

    Outstanding article. Mind-blowing in its implications for much cheaper energy for everyone. This kind of information is available no where else but at Veterans Today. A whole new energy future for most may be right around the corner.

    The excitement this could bring for the future could be the greatest stimulation in a long time for the masses to get involved in building a better future for all. This is the kind of information that can take the masses from a beat-down depressed state to excitement and involvement in determining a positive future for their nations and for their peoples. Highest commendations for this kind of article and the breaking news it contains, never before available.

    The nuclear “waste” being buried now could be used for cheap (free?) district heating schemes.

    • Gordon Duff  September 16, 2014 at 6:41 am

      Yes. Nuclear power has always been free, depending on what you mean by that. The primary excuse for charging for power has been bad reactor design and the myth of nuclear waste.
      If power is free, water is free and everyone can own an electric car that runs off free power.
      Then, of course, food would cost half and we would stop poisoning the environment.
      I am beginning to sound like a socialist, I will stop.

    • drbhelthi  September 17, 2014 at 12:26 am

      Is being accurate necessarily socialistic?
      Dr. Carol Rosin reported that Dr. Werner von Braun told her in the early 1970s that we could already be riding in wheeless autos that did not run on oil products. The bit of info that is available about Nicola Tesla´s electricity collector, with which he powered the electric-motor in the Pierce-Arrow, is fascinating.

    We’re considering selling fission reactors as “survivalist” gear. We can be like Infowars.
