I don't think so. The fisson products would all be relatively short
lived isoptopes, and teh main product is helieum. Non radioactve helieum


Its only the vast amounts of radiation intereacting with the shielding
that would cause some radioactive compounds to be generated.


No. In the reactions which are presently considered, there will be a lot of
tritium around. Tritium is a gas and it has a long half life. It scares
the pants off me.


Tritium isn't all that bad. Its half life of about 12 years is short
compared to millenia for fission waste. Tritium is a beta emitter with
18keV electron decay and there is quite a market in tritiated plastics
for permanent glow in the dark (and still some requirement for H-bomb
initiators). Emergency lighting in some applications is based on it.

Fission power is the cleanest and least polluting energy source ever
produced on earth.


Yes, I tend to agree with you.


You have to get the whole life cycle right though. And they still
haven't an adequate solution for long term storage of high level waste.
