At thet time I read that Hanford was pumping liquid waste from below ground tanks into double walled above ground tanks with provision for sampling any leakage from the inner to outer shell. This is an expensive stopgap. It happens that the activated fly ash can make a suitable and cheap containment for locally stored rods and liquid waste, far better than the metal and portland cement containment design postulated for Yucca Mountain. The basic chemistry comes from Dr. Daviovits, a Frenchman, but getting the proper governmental attention, or even research grants, runs into the usual thicket familiar to CF. The Great Pyramids were built with limestone concrete using a related chemistry, but that is another story. Mike Carrell
