ferroycanide? Does that just accumulate in the bottom of the tank? 



DR. CHRISTY: That is correct. 



DR. R. H. WILHEL.M: On self-evaporation what type of waste 

 do you get in the distillate, the "overhead?" 



DR. CHRISTY: It is essentially water. 



DR. T. P. KOHMAN: Does the uranium get into one of those 

 three wastes? 



DR. CHRISTY: An insignificant amount. 



DR. KOHMAN: But not the bulk of the uranium? 



DR. CHRISTY: No, not the bulk. 



DR. KOHMAN: Is the amount of nickel ferrocyanide sufficient 

 to carry out all of the strontium? 



DR. CHRISTY: I would say, essentially all. Nickel ferrocya- 

 nide is a highly efficient scavenging agent. 



DR. KOHMAN: There is always aluminum. 



DR. CHRISTY: This is something I didn't mention. Coating 

 wastes in the early days used to be added to the intermediate wastes. 

 When this process was developed, the coating wastes were diverted 

 into separate tanks so that it wouldn't interfere with the chemistry 

 which makes this process possible. Today there is no alternative 

 but to store the coating wastes. 



DR. KOHMAN: Fission products too? 



DR. CHRISTY: Fission products too. So we have to store all 

 our jackets or coating wastes. 



DR. H. C. THOMAS: Isn't it like the Irishman building a hole 

 to put the dirt into . Now what are you going to do with all the nickel 

 ferrocyanide ? 



DR. CHRISTY: That is a part of the problem being considered 

 by this group, I understand.
