I haven't done it, but Tony Appelo describes how to set up radial problems for PHREEQM in his book, Geochemistry groundwater and pollution (Balkema, he is working on a second edition). The same approach applies to PHREEQC. I think all you really have to do is define cell lengths that decrease with distance by the appropriate amount. From p. 423: length(1) = R/ncell^.5, where length(1) is the length of the first cell, ncell is the number of cells you want to use, and R is the maximum radial distance. length(n) = length(1)(n^.5 - (n-1)^.5), for cell n. He gives an example on pager 437. If you have problems, he can probably help you better than I (appt@xxxxxxxxx).
