REFERENCE:
U.S.N.R.C. " Environmental Review" Dated October 25, 1979 W
Westinghouse Electric Corporation Commercial Nuclear Fuel Division hereby submits an amendment request to License SNM-1107 to authorize the free release of industrial products (specifically hydrofluoric, HF, acid solutions) in which the conditions specified in the enclosed new Section 4.8 are met.
The proposed use of HF at Western Zirconium is similar to that at Brush-Wellman in that the HF remains in aqueous form throughout the process, and the uranium is eventually precipitated in a lagoon with zero discharge except for evaporation.
Attached is a letter dated April 15, 1987 from Dr. Donald Kaczynski of Brush Wellman affirming that their process has not changed since the above referenced NRC " Environmental Review" was performed.
Note that t
this letter references a maximum enrichment of 5% in U-235.
We believe that the higher enrichment does not modify the environmental analysis as l
documented in the October 25, 1979 NRC Environmental Review.
Westinghouse believes that this industrial use will have no significant adverse effects on members of the public or the environment since there are no pathways for the uranium to be introduced into a human ingestion
\\
chain.
The above referenced NRC " Environmental Review" is site specific to Brush-Wellman and indicates that "it is not expected that the proposed program has significant impact on the environment."
A check for $150 is included to cover the costs of this application. #

Hydrofluoric (HF) Acid Solutions Pursuant.to 10CFR20.302, authorization to transfer aqueous HF-acid solutions containing trace quantities of uranium to nonlicensed (NRC or Agreement State) facilities specified in 4.8.1.1 is granted provided the conditions in 4.8.1.2 through

The HF acid is transferred and used in such a manner that the minute quantity of uranium does not enter into any human
]
ingestion chain.
Prior to such
- transfer, each shipment will be representatively sampled and analyzed and the following maximum permissible concentrations shall not be exceeded:
Uranium:
less than or equal to 3 PPM (by weight)
Uranium-235:
less than or equal to 5% U-235 (by weight)
HF:
less than or equal to 50%
(by weight) 4.8.1.3 Quantities The estimated volume of this aqueous hydrogen fluoride solution is less than 50,000 gallons per year.
With a maximum. permissible uranium concentration of 3 ppm and a maximum enrichment of 5% in U-235, the maximum quantities of uranium and.U-235 in the 50,000 gallons that would be transferred would be approximately 334 grams uranium and 17 grams U-235 based upon the following:
Density 9.8 pounds per gallon Concentration 50% HF, 3' ppm U Enrichment 5% U-235 These quantities are insignificant, especially since the uranium and U-235 are not removed from the solution during l

4.8.1.4 Brush-Wellman_
See: attached letter dated April 15, 1987 from. Dr. Donald Kaczynski to Mr.
Edward Reitler and previous NRC
" Environmental Review" dated October 25, 1979.
4.8.1.5 Western Zirconium Dilute HF is used to pickle zirconium products in aqueous baths where.the HF is diluted' by approximately 9 to 1 with nitric acid (i.e., nine parts nitric acid to one part HF).
Following the pickling step, the zirconium products are rinsed with deionized water.
It is expected that the uranium will remain in the aqueous phase'. to the next step in the process (neutralization) 'where slaked lime is added to the.
aqueous waste.
Other Western Zirconium aqueous wastes are.
added to this stream' prior to neutralization, resulting in a total dilution of approximately 1,000 to 1.
Neutralized wastes are transferred. to ' evaporation - only lagoons for. long term storage.
These lagoons are currently licensed with the State of Utah.
A composite sludge sample from the lagoons shall be collected on a. quarterly basis and analyzed for isotopic uranium with an action level of 15 pCi (total uranium) per gram of dry sludge.
If the. total uranium in the sludge sample exceeds 30 pCi/ gram, the NRC Regional Office shall be notified within 30 days of the completion of the analysis-There are no pathways for the uranium to be introduced into a human ingestion chain.
The zirconium products are used in the nuclear fuel cycle or in the chemical processing industry.

Dear Mr. Reitler:
1 The extraction plant owned and operated by Brush Wellman Inc. in Elmore, Ohio consumes large quantities of aqueous hydrogen fluoride each year.
In June of 1979, Brush.Wellman's Dr. Ken Walsh, Asso-ciate Director of Technology, assisted General Electric in obtain-ing a NRC license to transfer about 100,000 gallons of dilute hydrogen fluoride for exclusive use by Brush in the production of beryllium pebbles. The maximum permissible concentration of l
uranium in this aqueous hydrogen fluoride was set at 3 ppm with a maximum enrichment of 5% in U-235.
1 i
The extraction process for beryllium used by Brush Wellman is i
identical to that used in 1979. We do not foresee this process 1
changing in the future. The reduction process converts metal fluo-rides produced from the aqueous hydrogen fluoride to pebbles or metal. Uranium is co-reduced along with the beryllium in this process and ends up in the final metal product. The fluorine is converted to magnesium fluoride, an insoluble solid waste which is disposed in waste treatment lagoons. All lagoons are maintained at a pH of greater than 8 such that metals present in aqueous wastes I
are precipitated.
As beryllium is a toxic substance, all extraction processes are carefully controlled such that airborne contaminants from the peb-i ble making process are eliminated.
In addition, as long as the concentration of uranium in the aqueous hydrogen fluoride is kept below 3 ppm, 7 ppm based on HF, the uranium which ends up in our beryllium metal oroducts will not pose any problems.

The use of dil'ute (less' than 70%)- hydrogen fluoride in our beryllium-making operation causes us to. incur higher costs than'if l
we'were.to'use concentrated hydrogen fluoride,iThi g in turn,
