Robin—
I agree with Jones. Neutron activation of reactor internal thermal shields intended to substantially protect reactor vessels from embrittlement results in a long term gamma source regarding waste disposal. It is second biggest issue next to the main issue associated with spent fuel remediation/disposal. The third issue is neutron activation of wear products produced during reactor operations and which get deposited outside the reactor vessel resulting in problems with maintenance and disposal of reactor system components. These products are called CRUD (Chalk River Unidentified Deposits) after the reactor where they were first observed. IMHO radioactive Nb with a 10,000 year half life is the worst problem associated with thermal shield activation. Co is a bad actor when it comes to CRUD, but is relatively short lived compared to Nb. Ni isotopes are also a long lived problem when it comes to disposal of reactor components.

But are you sure? Do you know what reaction it >is? Where does it say that? The neutrons from a DT or DD reaction are going to "activate" everything in sight. That's bound to result in at least some long(er) lived radioisotopes, although, it doesn't appear to be a major problem in nuclear subs. Perhaps it's just a matter of the right shielding?
