    The estimated quantity needed is 4 grams (0.14 oz) per warhead. [11] To maintain constant levels of tritium, about 0.20 grams (0.0071 oz) per warhead per year must be supplied to the bomb. One mole of deuterium-tritium gas contains about 3.0

    [citation needed] In Australia products containing tritium are licence exempt if they contain less than 1 × 10 6 becquerels per gram (2.7 × 10 −5 Ci/g) tritium and have a total activity of less than 1 × 10 9 becquerels (0.027 Ci), except for in safety devices where the limit is 74 × 10 9 becquerels (2.0 Ci) total activity.

  6. Helium-3 - Wikipedia

    en.wikipedia.org/wiki/Helium-3

    The total amount of energy produced in the 2 D + 3 He reaction is 18.4 MeV, which corresponds to some 493 megawatt-hours (4.93×10 8 W·h) per three grams (one mole) of 3 He. If the total amount of energy could be converted to electrical power with 100% efficiency (a physical impossibility), it would correspond to about 30 minutes of output of ...

    The normal amount of oxygen-18 present in the natural form is 0.204% while that of oxygen-17 is 0.037%. The reduction of the oxygen-17 and oxygen-18 present in the plutonium dioxide will result in a much lower neutron emission rate for the oxide; this can be accomplished by a gas phase 16 O 2 exchange method.

  8. Tritiated water - Wikipedia

    en.wikipedia.org/wiki/Tritiated_water

    In one CEA study, relatively highly tritiated water at 1,800 Ci/L or 74 TBq/L (0.12% HTO, negligible T 2 O) was left to self-radiolyze for 56 days in three volumes. In the 300 mL volume, the primary gases collected were H 2 at 2.54 mmol , O 2 at 1.31 mmol, and 3 He at 0.13 mmol.

  9. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    The density values for chemical fuels do not include the weight of the oxygen required for combustion. The atomic weights of carbon and oxygen are similar, while hydrogen is much lighter. Figures are presented in this way for those fuels where in practice air would only be drawn in locally to the burner.
