DR. HEDMAN: Could I get some idea of the volume that is 

 transported between a power reactor and a plant? 



DR. CULLER: Let's say the fuel elements are made out of a 

 metal like zirconium, and zirconium slag or stainless steel built in 

 a similar manner. It might be necessary to transport an element 15 

 feet long and 5 inches in diameter. In order to shield this after a rea- 

 sonable cooling period it would require about 8 or 10 inches of lead. 



DR. HEDMAN: That is within the realm of being practical. I 

 thought maybe you would have to transport large volumes of liquid be- 

 sides . 



DR. CULLER: No. If you shipped the fuel element within thirty 

 days after it comes out the reactor you would have to provide cooling 

 water to take out the fission products. You can put a number of such 

 fuel elements in the cask, and I suspect the size of the cask is deter- 

 mined by the limits of the carrier. If you have an 80,000 pound flat 

 car you make the cask 80,000 pounds. 



There is another factor that enters into it. If the fuel elements 

 are highly enriched you have to limit the number that go into the cask. 

 But I suspect if you have more cylinders of shielded lead on a flat car 

 you could transport a reasonable number of fuel elements at one time. 



The transportation is going to become a business like the power 

 business, I suspect, and it has never been looked at in this light. Reg- 

 ulations may have to be changed to take care of it. Right now it is a 

 big hazard and we are doing everything we can to make sure there is no 

 danger. 



DR. L. MacMURRAY: Dr. Morgan at Johns Hopkins has some 

 specifications on this question of transporting liquid wastes. Would you 

 like to have him present it? 



CHAIRMAN HESS: Yes. 



DR. J. N. MORGAN: After the first Woods Hole meeting, at 

 Johns Hopkins we made a few observations based on Dr. Culler's paper 

 concerning the transportation of liquid wastes. These figures are based 

 upon the information concerning shipment of slugs throughout the United 

 States. The cost of the cask, the transportation cost, the carrier cost, 

 the salaries, and amortization of the cask, total 9 cents per ton mile to
