  • OK, to sum up so I can stop wasting my time on you: Yes nuclear fission releases Tritium; a radioactive isotope of hydrogen,which therefore can be hydrogen gass. It can also be found in tritiated water instead of hydrogen.Yes tritium is somewhat harmfull to the body and can cause mutations in the DNA.But the video is about nuclear FUSION. Fusion USES tritium gass/atoms as a fuel, together with deuterium, and 'creates' helium as a waste --> Fusion = OK. Fission is not so great. You agree now?????

  • "Since tritium is a low energy beta emitter, it is not dangerous externally (its beta particles are unable to penetrate the skin), but it is a radiation hazard when inhaled, ingested via food or water, or absorbed through the skin. It has a short biological half-life in the human body of 7-14 days, which reduces the total effects of single-incident ingestion and precludes long-term bioaccumulation of tritium from the environment." TRITIUM IS NOT RELEASED IN FUSION, BUT IN FISSION<-- IMPORTANT!!

  • It is quite basic science that Fusion does NOT emit/excrete (whatever) Tritium. That's like saying a car spills petrol. Tritium is produced for fusion; D + T --> He-4 + n (T=tritium). All tritium is produced at the facility (from lithium-6) and used up inside the closed tokamak. The only waste of fusion is helium. Those are the facts on fusion. La Hague is not a fusion, but a fission reactor, so you're off topic (I agree that nuclear fission is bad).

  • Because reactors depend on heavy water as a moderator, they release larger amounts of tritium to the environment than light water reactors (…) Tritium is a carcinogen, mutagen, teratogen and developmental toxin. It becomes incorporated into DNA and disrupts the genetic code of men’s and women’s reproductive cells. current Guideline and Drinking Water Quality Standard for tritium is 7,000 Bq/L, which is based on the permissible ICRP dose limit of 1 mSv/year (lowered to 0.1 mSv in water).

  • This “standard” corresponds to a risk of 350 excess fatal cancers per million people from just one year’s consumption of drinking water, not a lifetime (70 years) 300 million people living in the US: 105,000 DEATHS PER YEAR x 30 years = 3,150,000 murdered people by the peaceful atom! Multiplied x global = weapons of mass destruction.

  • n the form of tritiated water, the isotope of hydrogen can enter the food chain and set in the body, leading to damage and mutations in DNA. ASN in its “White Paper Tritium” published on Aug 7th 2010, revealed that they had underestimated the possible consequences of this radionuclide on the environment and living organisms, the risk estimate was incorrect, that further research was needed. (PART 1)

  • (PART 2) The authors of this paper conclude that “the re-evaluation of the toxicity of tritium requires to revisit the practices on releases and storage of tritiated waste,” giving due warnings of long-standing Commission for Research and Information independent radioactivity CRIIRAD. Studies of the confinement and release of tritium in ITER have not been adequately carried out while the construction of ITER is already underway!

  • tekknorg, this comment does not make any sense. it is irresponsible to say that tritium will be released in substantial amounts. it's simply not true.

  • Tritium is a radioactive gas, highly toxic if inhaled. It falls to earth with precipitation in the form of tritiated water. The tritium atoms can replace hydrogen atoms (about half the atoms of the human body are composed of hydrogen) and in the form of tritiated water, the isotope of hydrogen can enter the food chain and set in the body, leading to damage and mutations in DNA. ITER / Fusion releases Tritium. ITER / Fusion consumes 100 billion € - missing in clean renewable energy.

  • @Tekknorg Tritium is not released in fusion... it is one of the fuels for fusion. It is easily produced in a fusion facility by shooting a beam of neutrons at lithium-6. That means that all (very small amounts) tritium is created and used up inside the facility. Even though inside a fusionreactor temperatures go up to 150 million degrees, when you pull the plug all processes stop, unlike a fissionreactor in which a chain reaction keeps on going for some time. What i'm saying is; fusion is safe!!

  • @topperboy94 First sentence, first lie. Tritium is waste and highly toxic. it is created by Fusion. Fusion energy was inventedy in 1954 by world's first hydrogen bomb explosion. Nuclear fission and nuclear fusion - both invented by the military. You are not informed about Fusion energy.

  • @Tekknorg You are incredibly stubborn and dumb. Tritium is a radioactive isotope of hydrogen, with one proton (like all hydrogen) and two neutrons. Because it is unstable it is not present in nature, so it has to be produced. It is true that if you drink water that has tritium instead of usual hydrogen, you will not be improving your health. I am not sure about the concequences but it could simply kill you by radiation poisening or cancer. Anyhow it will be out of you body in 12 years. not done

  • @topperboy94 To continue... this should actually be enough: 2H + 3H > 4He + n . This is the fusionreaction that is used (because it is easiest) in JET, predecessor of Iter and which will be used in probably all fusion. 2H is deuterium, a stable isotope of water which is about 0.015% of all hydrogen atoms. 3H is tritium, smartass. What you probably mean is that the one neutron (n) hits the walls of the reactor with a lot of energy. these walls are lithium-6 and so, tritium is formed.

  • @topperboy94 still not done; this is however very convenient as this Tritium can be then reused in the original reacton. Dont underestimate youtubers; I may be seventeen, but I know my sources. As a matter of fact, I have spent the last half year 'researching' fusion (apostrofes because it was a literary research) for my graduation essay. In dutch its called profielwerkstuk, hope to hand in the final version in 4 weeks. Check iter.org before saying anything more... xD

  • @topperboy94 Despite your insults: Tritium= GAS = can not be hold back. It is emitted as gas by chimneys of ALL nuclear plants and also ITER. First thing you have to learn. Maybe basics for you.

  • Comment removed

  • @topperboy94 And you didn't answer, but insult.

  • @topperboy94 Tritium is created by FUSION and FISSION. Learn basics. Fusion is the daughter of the hydrogen bomb.

  • @Tekknorg Wikipedia even says "Tritium is a radioactive isotope of hydrogen". In other words; tritium is hydrogen... but different. So yeah; it's a gass; hydrogen. And yeah, it can take the place of other hydrogen atoms in water, body, plants. but NO; fusion reactors do NOT emit Tritium. Perhaps fission reactors do, but for fusion Tritium is one of the fuels. Read description/view video: in a fusion reactor they "seek to create a deuterium-tritium plasma..." On the other hand; the hydrogen bomb.

  • @topperboy94 ... The hydrogen bomb does indeed rely on nuclear fusion, which does create an explosion MANY TIMES MORE POWERFULL than a traditional nuclear bomb. But there is one big difference, why the hydrogen bomb is much better than a nuclear bomb; radioactive pollution: The Hydrogen bomb, like other kinds of fission, DOES NOT create radioactive substances; it uses one (Tritium.. .duuuh). The worst thing in nuclear bombs is not the huge explosion, but the results of radioactivity. I'm DONE :P

  • @Tekknorg haha, I checked your channel... and you're just afraid of anything that harnesses and generate large amount of power. Please listen to reason: Even though Fusion power is, like nuclear fission, a Nuclear power (power gained from the Mass Defect of the nucleus (core) of an atom). On any other respect, Fusion is nothing like fission: because the traditional nuclear power (fission) is so awful, can cause such great disasters and creates radioactive waste, doesn't mean fusion is the same.

  • @topperboy94 Again, your answer is neither scientific nor ethic. Learn basics. tritium is highly toxic, is produced by fission and fusion and replaces H² of our body. It is indeed the cause for increased children cancer, such as leukemia.

  • @topperboy94 La Hague emits 1000,000 Curie of tritium each year. 1 Curie per km² = 37,000 Bequerel per m² soil. Means: 37,000 radioactive decays. No longer harmless.

  • @topperboy94 tritium emissions result in elevated nuclide concentrations

    in vegetation and foodstuffs near reactors. This tritium concentration/distance

    relationship is very similar to the risk/distance relationship of children's cancer.

    The test for nuclear fusion realisation on Tokamak's installations and with LASER cannot bring anything new for the energetics' future. I bind the thermonuclear controlled reactor schedule by the Sun model , by the reactive electromagnetic motor schedule from Palenque stone's tombe. You see the my project for thermonuclear controlled reactor.

  • • SandustanBrasov

    The spherical thermonuclear combustion chamber is formed from two joined semispherical parts. The feeding with fuel and electromagnetic filed flux it make through the oriffices from the central part of the semispheres, and the emergence in outside to the electromagnetic field flux it make through the maximum zone, where is joined the semispheres. The two high-speed motors are rotated in the same sense for to establishes a direct electric field between collectors.

  • @sandustanBrasov

    there are no two high-speed motors in ITER. you are completely wrong, and i dont think you understand the physics behind this device.

  • • SandustanBrasov

    This reactor has spherical combustion chamber, with inner magnetic trap, with the electromagnetic field realized outside and introduced inside the sphere with electromagnetic field and fuel introduction device, and direct colected possibilitys of electrcal energy, with semispherical collectors. The device of introduction is composed from: 1).-two high-speed motors with plasmatron in its central zone; 2).-two magnetic circuits for leading the electromagnetic field flux.

  • @sandustanBrasov

    the reactor is not spherical, its a toroid. a donut is not spherical, because of the hole, a donut is a toroid.

    when you leave comments saying this has a spherical reaction chamber, you are simply spreading wrong information and confusing people.

  • • SandustanBrasov

    Thus, with a sure magnetic trap, without switchs of heat and with the direct extraction to the electrical energy=to the particles of electrical ether, it can pass direct at the final phase of obtaining to the commercial controlled thermonuclear reactor. I consider that the price of research and realization in this case, can be of at least 10 times more small than the actual ITER project, and separated can be realized of many countries.

  • @sandustanBrasov

    electrical ether?

    you are one of these pseudoscience-fanatics that treat modern physics as if it were some new age spiritual stuff. nothing you say makes any sense, you just leave tons of comments that sound scientific, but most of it is wrong.

  • • SandustanBrasov

    I turn the globe of plasma for to realize the magnetohydrodynamic principle of directly extraction of the particles of current(electrical ether). The atoms of helium after formation can pass through the texture of the magnetic trap as residue. The electromagnetic field of the magnetic trap must let enter with power for to space out, to press, and turn with 800 m/s the globe of plasma and afterwards fastly let go outside.

  • • SandustanBrasov

    Feeding a superconductive coil with an electrical current it obtain in the her round only a magnetic field. But disposing in the round of the superconductive coil a certain magnetic and dielectric pieces, it obtain the variation of the electrical permitivity and of the magnetic permeability, which will transform the magnetic field of the superconductive coil in electromagnetic field, which can evolve(go) more faraway in space, without to close immediately the curl.

  • • SandustanBrasov

    In the magnetic trap of the tokamak installation it produce only magnetic field which it maintain in the round of the coil without to fulfil the role of magnetic trap. The electromagnetic field can evolve(go) in space and in the interior of one spherical chamber, can be weaved in order to form a stratified network, which let hold the particles of the thermonuclear plasma.

  • • SandustanBrasov

    • The texture of toroidal, poloidal or stellarator magnetic field is too rare for to form a magnetic trap. The magnetic trap must let be one electromagnetic stratified wall with weaved at entrance and with disweaved at emengence. The electromagnetic wall of the magnetic trap is a wall with formation and continuous displacement.

  • SandustanBrasov

    The Sun has two sorts of magnetic field: 1)-the principlal magnetic field of the solar magnetosphere which dress the solar mass; 2)-the secondary magnetic fields which pass through the whirligig tubes by one hemisphere in another. Because the rotation of the solar mass the lines of the secondary magnetic fields are not parallel with lines of the principal magnetic field, but are adjacent and thus it form at the surface of the Sun a texture of magnetic lines as a magnetic wall.

  • • SandustanBrasov

    The conditions of thermonuclear controlled fusion: temperature, concentration, confinement and duration - can not obtained never in a tokamak installation, because the her incapacity of the magnetic trap, which can not dress and sourround whole the thermonuclear plasma. The plasma can not be restrained, can not be maintained and thus can not be heating. Till now 2011 - was confined not the plasma on the tokamak installations.

  • • SandustanBrasov

    Through divertor it remove the impurities from the chamber of thermonuclear combustion and it consider the single zone where the plasma is leted free let touch the walls. Really is good? really is logical this construction? If will be not existed the solar magnetosphere with her magnetic trap as let dress complete the incandescent solar mass, then the our planet can burn and remain without water.

  • • SandustanBrasov

    The Sun shows us how it prepare and how it produce the thermonuclear reaction, and the resonant generator of the Tesla show us how it can extract the electricity= the particles of the electrical ether, without to utilize the switchs of heat. The ethereal explanation of phenomenon is necessary because in outside of electricity= electrical ether, all ethereal substances are: the electrons, the inductive magnetic field, as and the electrical field.

  • geo thermals have limits to efficiency

  • instead of underground housing for illuminati and elite for protection at armageddon how about working on geothermals? best episode yet!
