RE: nuke navy - HMS Tireless - probes

You're kind of comparing apples and oranges.  An RTG operates from decay

heat, not fission.  Different isotope, and probably much greater macroscopic

concentration, since the radioactive material is in a 'chunk', rather than

being dispersed in fuel rods separated by moderator, etc.

This thread brings up an interesting question to me.



The thermocoupler reactors in the voyager and pioneer

exploration of space have easily lasted 20 years.  Is

there a similar concentration in nuclear submarines -

as there is in these space probes?



Please note the operative word is "concentration".  



Thanks to everyone for allowing me to ask this - Tom
