Where Does U Go? AEC isn't stockpiling uranium raw materials, but it does have a lot in process

I s AEC STOCKPILING uranium? Not intentionally, says David F. Shaw, Atomic Energy Commission's assistant general manager for manufacturing. However, he adds, all uranium winds up in stockpiles of either plutonium, enriched uranium, or depleted ura­nium. These stockpiles, created in the process of meeting defense needs, will probably turn out to be the source of future atomic energy.

Rumor has it, Shaw says, that the Government will continue to stockpile uranium until 1966, and some call this program "overextended." They think AEC should curtail uranium purchases to help reduce government expense for the next few years. This is a false im­pression of the situation, Shaw points out. AEC buys uranium currently only for process feed in its plants; it has no objective so far for building a stockpile of uranium raw materials.

To understand where AEC's ura­nium really is, the processes taking place as the metal approaches ultimate use in the fission process must be recog­nized. These processes, Shaw told the Uranium Institute of America, meet­ing in Denver, constitute the produc­tion part of the atomic energy pro­gram. They also indicate the where­abouts of the uranium owned by AEC. Shaw accounts for it in:

• Plutonium, created a t the expense of some U2 3 5 , delivered t o the weapons stockpile.

• Highly enriched U 2 3 5 also de­livered to the weapons stockpile.

• Uranium of various enrichments of XJ235 withdrawn from diffusion plants for research, for reactor fuel, and for use under the atoms-for-peace pro­gram.

• Depleted, uranium, low in U2 3 5 , from diffusion plants which accounts

for the largest part of the uranium processed.

• In-process inventories of consider­able size.

Uranium "in process" at AEC plants includes the concentrates awaiting solu­tion at refineries and varying amounts of orange oxide ( U 0 3 ) , green salt ( UF 4 ) , and metal in process or in transit between feed material plants.

Several thousand tons of the ura­nium are always being irradiated at AEC's 13 large production reactors. A charge for one of these reactors, Shaw says, is several thousand fuel elements. Each element contains pounds of uranium.

More tons of uranium are in storage awaiting chemical separation, Shaw says. The waiting period allows highly radioactive products in the irradiated metal to decay before further process­ing.

At gaseous diffusion plants, hun­dreds of tons of uranium are in equip­ment and piping. Each of these three plants involves about 300,000 miles of piping, a large part of which is filled with gaseous uranium hexafluoride at all times.

Shaw says AEC constantly reviews the uranium stockpile question. The commission now has firm commit­ments that will supply all present plant feed requirements. Therefore, he says, the time is approaching when it will be feasible to buy for a raw materials stockpile if it is deemed important to national interest.

G-E silicone Anti-foam 60 disperses faster, controls foam more economically

Rapid dispersion of small, uniform particles o f anti-foam material is the key to fast, low-cost foam con­trol. Here the performance of General Electric sil icone Anti-foam 60 is outstanding. Anti-foam 60 dispersées almost instantly into minute, uniform particles tixat destroy foam bubbles fast.

And with G-E Anti-foam 60 you get maximum benef i t from s i l i c o n e ' s i nhe ren t foam-des t roying action, and get it more economically because only a few parts per million are needed in most foaming systems.

If defoaming can reduce your processing and fill­ing time, eliminate costly boil-overs or i ncreas^e yomir batch capacity (in aqueous systems), get a free test sample of General Electric Anti-foam 6(0 by mai l ing the coupon below. We think you will find, a s many

For n o n - a q u e o u s sys tems—

G-E silicone fluids and compounds are also avail­able for efficient low-cost defoaming of non-aqueous systems. Ask for free samples of SS-66 or SF-96.

SS-66 is a low-viscosity silicone anti-foam com­pound. Typical uses include defoaming during esteri-fication of vegetable oils—as well as in paints, inks, antibiotic fermentation and phenolic resin cooking.

SF-96 fluids are available in standard viscosities from 40 to 100,000 centistokes for defoaming all hydrocarbons from light-end gasolines to heavy-end asphalts.

WÏÏVÉMKIQ lUJ Rfl drastically cuts anodizing rack replacement

Titanium has proved to be an excep­tional material for anodizing rack construction. In typical cases, tita­nium racks have outlasted conven­tional materials by as much as 30 tim es. This far outweighs the increased original cost.

Titanium forms a thin, stable protec­tive oxide film when exposed to air. Likewise, titanium polarizes readily and forms a protective film when ano-dized by a direct current in an elec­trolyte.

In addition to offering exceptional corrosion resistance to electrolytic solutions, titanium retains its current-conducting ability, This saves time and labor ordinarily required for strip­ping the rack after each use.

Mallory-Sharon produces high quality titanium in standard shapes—rod, bar, sheet, strip, wire, etc. This mate­rial is being used by several anodizing rack fabricators. We'll gladly supply information that can help you reduce anodizing costs. Please write Dept.N 11.
