,j SUaJECTt Special Nuclear Fatoriala Licensg No. Sh33 bear Mr, Johnsm:
In answer to your letter of March n requesting additimal information on cur applications for amendment of our Special Nuc2aar Materials License No SNM-33, we are pleased to nply an follows:
I, Pe11 sting Procos_s, 1.
High assay mterial (above approximtely 10%) has a " limited safe" batch site too omu to be adequately blended in the large mechanical open pot blander. For those materials, blending with the lubricant and moisture necessary for proper pellet manufacture will be accomplimbed in a sman household blonder with similar =4ving action. 'this blender has been found quita satisfactory for experimental blending at 3/2 pond batch size, The blender will be housed in the dust hood and operated at not l
mare than a " limited safe" batch.
2.,
Two types of granulating equipment have been found entirely satisfactay for our purpose., One is a sisp3a screen in which the blamied powder con-taining lubricant and moisture is' forced through a proper size scamen for sising. The other type of equipment is an approzisately 3" diasster j
"mes.t grindor". In au c:.ees, the " limited sofo" batch used in the blend-j ing operation win be processed as a singla batch through.the granulating i
equiposat to insure nuolaar omfets e

The ;tostion on this application has reference to tho hydrolysin equip:: ant, Two hydrolysic and precipitation tanks will bo used - ona for low accay mterial and one for high assay sterisl, A singlo cylindor heating station on an accurate scale win be avaihble. A singh punp for circuls-tico cf the water and slurry win be installod, Fhnged pipo connectieno have boon designed to connect the cylindor heating station to either the Ica or high assay hydrolyais unit. Fhnged pipe connections have been decigned to connect the single pump to either the high or low assay hydro 2yais tank, Defore a cylinder can be removed from the locked position in the warehouse, the lianager and Foreman n:aks an inspection of the piping arrangement in the hydrolysis hood to determine that the proper fhnge connections are inst 2ned and that the unused connections are romoved from the system and the unused flange blankad off.

uranyl The shipping omtainer for colutions or crystals of uranyl nitrate, h-1/2" fluoride, and uranyl sulfate win be polyethylene bottles made from i
I.D. polyethylene pipe with suitable top and bottom pieces welded thereto, he wan thickness of the polyethylene is 3/16", B e maximum outsido N
dimension of the bottle and its fittings (at the top and bottomweld junction) ish-15/16". We have designed ' stainless steel muisters 5" I.D. with f3anged tops to receive these polyethylene bottles' We anticipato using two sises of po3pethy3sne bottles - ene approximate 2y 35" high and.the other 13" high.
Nee bottles and the stainlass steel f3anged container will be firm 3y placed inside birdcages which maintain 2h" spacing between adjacent containers. In all cases the salt or solutions win have a U888 density not to exceed 3<3 g/ce.
If wa interpret criticality data publinhad by tho AEC and its cca-tractcys proper 3y, theno dimnciens and theco concentratiens give us nn 4
