We have given thought to making pipe of carbon steel, but the 

 difficulties always seem to be resolved by using stainless steel. The 

 lines are built of about 3-inch pipe, but there is no reason they cannot 

 be made larger. 



DR. HUBBERT: How much does it cost per mile? 



DR. LINDSEY: I don't know the accurate figure, but it is some- 

 thing on the order of one hundred thousand dollars. 



DR. ROEDDER: If you have disposal at just a few places you 

 have to transport either the waste to those sites or you have to set up 

 your processing plants at disposal sites. I would imagine that the 

 cost of transporting slugs would be far less than the cost of transport- 

 ing waste. Is that not true? 



DR. LINDSEY: We have not transported liquid wastes. We are 

 afraid to. We have transported slugs on a large scale and for quite a 

 while. There is no reason why we couldn't work out a way to trans- 

 port liquids. It just doesn't seem as safe as transporting the slugs. 



DR. RUSSELL: May I remark that the A.E.C. can get away with 

 a great many things in this country that a private corporation operating 

 a power plant would not be permitted to do. 



DR. KOHMAN: With regard to transportation I think one would 

 have to consider the relative cost of transporting the materials and 

 transporting the power. In other words, whether the power plant is to 

 be near an area where the material is to be disposed of, or near the 

 area where the power is to be used, or not near either one. 



DR. HUBBERT: Mr. Chairman, I would like to make a further 

 comment on that. It is a truism of sorts that with any technology de- 

 velopment, you begin to tie on where you are now, but as time goes on 

 you sometimes abandon the initial premise. It seems to me this is a 

 strong possibility in the case at hand. At the moment, we are talking 

 about building atomic power plants for industrial power -where we al- 

 ready have coal power plants. The reason for that is perfectly obvious: 

 we use 60 cycle AC current and the economic transmission is about 400 

 miles. Many of you know that there have been theoretical discussions 

 and a fair amount of experimental work that dates back thirty or forty 

 years on high tension DC long distance transmission. It is physically 

 possible but it has never been done. In principle, you generate AC to 

 high voltage, rectify DC, and transmit it great distances; then convert
