A capsule certified to held for over 10 years pressure 5 atmospheres
should be able to hold some radiation as well.
I'm interested in.
1. Mass of fuel.
2. Mass of reactor.
3. Mass of ****eld per 1 m^2.

Is something wrong with saying, an industry standard material for
gamma ****elding has "a" reduction of neutrons per 10 mm, 1 m^3 weights
"b"? For data, or theoretical materials look at http://xxxx.pdf
and
prepare yourself to vomit.
Group for these questions was abandoned few years ago, and I wondered
if someone from here doesn't have real live data. People that like NEP
frequent NASA boards, so I might find someone who recal some sensible
materials on theirs boards, however I don't like NASA boards.
