Naturally-occurring chemical analogues for repository-derived radionuclides
- QuantiSci Ltd., Melton Mowbray (United Kingdom)
Studies of natural systems are a valuable means of gaining information on the behavior of elements and radionuclides in the geosphere or biosphere that may be used to support performance assessments for radioactive waste repositories. However, these natural system studies face the problem that some of the chemical and isotopic species that occur in radioactive wastes do not occur naturally. Therefore, when attempting to study transport processes for these species other, naturally-occurring species must be examined as {open_quote}chemical analogues{close_quote} for the waste species. Chemical analogues are chosen on the basis of some similarity with the chemical behavior of the waste species in relevant physico-chemical environments. This is a tricky procedure and each system must be considered on a case-by-case basis, although some guidelines can be established and these are given here.
