Thank you for the article. I have read it, and here is the problem. A TBR of 1.14 for the blanket is a problem because that is an ideal breeding ratio before you account for loses in the process of actually extracting the tritium from the blanket and using it some time in the future. Remember tritium is a form of hydrogen which diffuses wonderfully through most materials. Losing >>10% in pumps, vacuum walls etc. is expected. While it is unclear, it seems that the author has also imposed an unphysical boundary condition on his presumed neutron reflectors at each boundary.
But fundamentally, the problem is that a theoretical ideal breeding ratio of 1.14 is woefully insufficient when real world practicalities of losses in processing, transfer and Tritium decay are accounted for.
” TBR of 1.14 for the blanket is a problem because that is an ideal breeding ratio before you account for loses in the process of actually extracting the tritium from the blanket and using it some time in the future.”
You claimed less than 1.0
Due to supply. problems, tritium will be extracted and used in very short times.
” Losing >>10% in pumps,”
I would expect that the tritium would be extracted BEFORE reaching the pumps.
“Remember tritium is a form of hydrogen which diffuses wonderfully through most materials.”
How is Canada storing their tritium?
How does the tritium stay in H-bombs?
