DR. A. RODGER DENISON: You mentioned solids in some of 

 these wastes. Do all the wastes have solids as they go into the tanks? 



DR. CHRISTY: Yes, they do. 



DR. MURRAY HAWKINS: Are these Type 1 wastes you are 

 talking about? 



DR. CHRISTY: Certain of these will be found in each of the 

 wastes that we have. For example, some will in the coating wastes, 

 some in the first cycle, second cycle, and third cycle and some in the 

 wastes from the new plants. 



CHAIRMAN HESS: Are there any further questions? 



DR. J. W. WATKINS: I would like to ask if you are not con- 

 cerned with technetium because of the low energy. 



MR. J. A. LIEBERMAN: I don't know that I can answer that 

 question specifically; maybe some of the other men can give a hand. 

 As a biological hazard it is of much lower magnitude than strontium 

 or cesium. Whether it has intrinsic value as an element I don't know; 

 I think there has been some mention of recovering it for its value. 

 But from the biological standpoint, to my knowledge it has never been 

 given as a neuclid to be concerned about. 



DR. H. C. THOMAS: I was just looking in the book to see if I 

 can find it. I don't believe that there is any biological hazard given 

 with it. 



DR. T. P. KOHMAN: Because of its long half- life , its activity 

 is quite low. It forms a minor fraction of the total fission product 

 activity . 



CHAIRMAN HESS: Are there any other questions? 



DR. L. B. RILEY: What is the rate of heat production from the 

 nickel sludge, the high level sludge? Is it 1 to 3 Btu/hr /gallon given
