Dear Mr. Johnson:
In carrying on our work of processing UF6 to UO2 or in recovering uranium-values from scrap, we have a need to conduct studies on small lots of various types of naterial. For exarple, we need to examine representative samples of scrap to deternine anticipated recovery costs. We request that our license application for handling special nuclear material, dated September 15, 1957, be amended to permit handling of these snall lots containing less than 1 Kg of uranium 235; also, a license to process and conduct studies on thorium in amounts up to 10 Kg is requested.
I Specifically, we have an imnediate need to handle the following:
(1) Uranium containing 21% U-235.. We understand this material
,y]
-is a slurry of uranium exide, grinding oil and various con-b ta:-inants resulting from grinding UO2 pellets.
A Th0 UO3 mixture consisting of natural uranium. We under-(2) 2 et:nd thib naterial has been used in a pumping locp.
Cur aim in exarining each of these materials will be to stuRr the processing necessary to recovering the uranium and thorium values in order that we night provice cost estinctes on this. He expect the processing steps to include dissolution of valuable caterials, purification by required solids separation, for exaq.le filtration and solvent extraction, precipitation and/or reduction o; oxidation to the required product.
The processing studies involved will be conducted apart from the equipment described in our reference application because the quantities under considera-tion will be less than suitable for handling therein. The processing will be 8301200059 821214 PDR FOIA DARNES82-562 PDR i.

r Decenbar 19, 1957 USAEC essentially batch type operation in which container sizes up to h liters are used. Only one batch containing no nore than 1 pound of U-236 will be in pro-cess at one time, and interaction of these :.aterials with other naterials will, be prevented by maintaining a distance of at least 10 feet between possible interacting materials.
In storage, where interaction is possible, " bird cages",
as described in our main application, will be used.
Very truly yours,
