I don't think there would be any problem setting up a manufacturing system for making dry ice on site, other than the site radiation levels. If the dry ice were manufactured in pellet form it could be distributed more easily via some kind of pumping system. However, there might be a problem with the dry ice being so cold that coming in contact with very hot fuel rods might induce cracks, but that's just a guess on my part.
