RE: Decision on nuclear fusion reactor site put off again



RE: Decision on nuclear fusion reactor site put off againNo.

The first reaction in the sun is the proton-proton or p-p fusion reaction

which produces deuterium by way of the weak nuclear force interaction.

Nothing else would happen without this first reaction.

This is what is meant by the statement that the sun's energy depends on the

weak nuclear force rather than the strong nuclear force.

By contrast, fusion reactions in ITER-type reactors and in H-bombs never

involve the weak nuclear force, because they use heavy hydrogen isotopes

like deuterium and tritium.

If you put ordinary hydrogen into either of these, nothing happens.

  Hi Jaro,



      Solar nuclear reactions consist of both strong and weak interactions.

  The basic fusion reactions that combine hydrogen isotopes to istotopes

  of helium are governed by the strong interaction forces, usually followed

  by a beta decay (either positron or electron) which are governed by the

  weak interaction forces.  In mature stars and particularly in supernova

  explosions, nucleosynthesis (involving both s- and r-processes) also

involve strong interactions, again followed by many beta-decays that

  are weak interactions.  So take your pick.



  Have a nice day,



  Fritz

    The ITER project is aimed at creating the world's first sustained

    nuclear fusion reaction, similar to the energy-producing process

    taking place constantly in the sun.

    Comment :



    Reactions in the sun depend on the weak nuclear force, whereas D-T

fusion in ITER-type reactors depends on the strong nuclear force : the two

are not at all "similar," except for promotional propaganda purposes.
