Greetings again,


     From:  jpreisig@aol.com


     Thanks to Jim Dukelow for his appropriate comments.  I'm all for fission

when it is cold and dark outside (i.e. winter) and I need to get warm.

Curious how fission goes back to 1938 or so (or about 1945 for Fermi's first

reactor), and fusion dates back to about 1950.  Fission has come so far.

Fission was understood and promoted by industry.


     Clearly, the deuterium on tritium reaction makes 14 MeV neutrons.

Great stuff, for a guy like me who sometimes does Bonner Multisphere

Spectrometry of neutrons.  I know of some research, back in the 1970's or so,

to study fusion reactions which might not produce neutrons (i.e. 

aneutronic reactions).  Haven't heard much about it lately.


    As for what is going on with fusion lately, I refer Jim Dukelow (and 

others)

to the Princeton Plasma Physics Lab. Web pages (PPPL) for recent 

information on the NSTX (National Spherical Torous Experiment) fusion

reactor.  The TFTR (an old style Torous) has been shrunken down to a

spherical fusion reactor, which is considerably smaller than the original

TFTR.  PPPL researchers continue to make progress with the NSTX.

Yeah, it has been 50 years or so, and I'm sure fusion reactor designs 

for industrial power use are still a few years off.  Oh well.


     Hope all is well at PNL!!!!
