NUCLEAR REGULATORY COMMISSION
[Docket No. 70-1257]
Finding of No Significant Impact and Notice of Opportunity for a
Hearing Amendment of Materials License SNM-1227, Siemen's Power
Corporation Richland, WA
The U.S. Nuclear Regulatory Commission is considering the amendment
of Special Nuclear License SNM-1227 for the Siemen's Power Corporation
(SPC) facility located in Richland, Washington, to authorize the
release of hydrofluoric (HF) acid containing less than 3 picocuries per
milliliter (pCi/ml) of uranium for unrestricted use.
Summary of the Environmental Assessment
Identification of the Proposed Action: The proposed action is to
amend SPC's license to allow the sale of hydrofluoric (HF) acid
containing less than 3 pCi/ml of enriched uranium for use in the metal
treating and chemical compounding industries. The acid is a co-product
of the dry conversion process used by SPC to convert uranium
hexafluoride (UF6) to uranium dioxide (UO2) for the
fabrication of nuclear fuel. This amendment and assessment address only
the sale of the HF acid co-product.
SPC is planning a major expansion of the dry conversion process and
expects to increase the generation of HF acid as a result of this
future expansion. SPC will apply for an amendment to expand the dry
conversion process in the near future. This expansion amendment will be
the subject of a future environmental assessment.
Need for the Proposed Action: SPC is authorized to store liquid
process wastes in on-site lagoons and to dispose of the treated liquid
wastes via the sanitary sewer to the Richland Wastewater Treatment
facility. SPC currently discharges 45-50 metric tons of fluoride
annually to the sewer, generated from the currently-operating ammonium
diuranate (ADU) conversion lines and the prototype dry conversion line.
SPC plans to expand the dry conversion process capacity and to shut
down most of the ADU conversion process. This expanded dry conversion
process will generate HF acid as a co-product. Sale and reuse of the HF
acid from the expanded dry conversion facility will allow SPC to reduce
significantly the amount of fluoride sent to the sewer.
Environmental Impacts of the Proposed Action: SPC performed a
pathway analysis to estimate the total doses to an individual resulting
from the sale and reuse of the HF acid and to demonstrate that these
doses will not exceed the standards for protection against radiation
set forth in 10 CFR Part 20 and that they are as low as reasonably
achievable.
SPC estimated radiation doses to a maximally exposed individual,
identified as a worker handling the HF acid in processes, including
chemical milling and passivating, and in the manufacturer of cleaning
solutions. The analysis considers that HF acid is highly toxic and
corrosive. Doses to members of the public will be much lower than doses
to individuals working with the material in an occupational capacity.
The results of the analyses demonstrate that doses to a maximally
exposed individual are less than 0.4 millirem per year internal dose
and less than 0.02 millirem per year external dose.
The potential for public exposure to radiation from transportation
accidents was also considered. The HF acid will be transported by truck
in 320-gallon tanks from the Richland facility to a buyer, following
Department of Transportation regulations (49 CFR Parts 173 and 178) for
the transport of HF acid. In the event of a transportation accident
involving the spill or release of the acid, fumes could be released. In
that case, radiation exposures, to an individual member of the public
could occur. However, the exposures would be of short duration, because
of the toxicity and corrosivity of the HF acid, and would be
considerably less than the worker dose estimate analyzed above.
Emergency response actions would be carried out based upon the chemical
hazards of the materials, not the radiological hazards.
Following start-up of the expanded dry conversion facility,
approximately 90 percent of the liquid wastes currently being generated
by the manufacturing facility will be eliminated as the dry conversion
process is brought on-line and the ADU conversion process for UF6
is closed down.
Conclusion: The dose assessment performed for the proposed action
demonstrates that the doses received by members of the critical group
and the exposed general population are well below the dose limits of
100 mrem/year and 25 mrem/year, as specified in 10 CFR Part 20 and 40
CFR Part 190, respectively, and are as low as reasonably achievable. To
ensure that these dose limits are not exceeded, the staff recommends
that the uranium concentration in the HF acid not exceed 3 pCi/ml in
any batch of 20,000 liters.
Consultations with other agencies and interested persons have
demonstrated that approval of this amendment will not violate any other
federal, state, or local laws or regulations.
The staff concludes that there will be no significant environmental
impact associated with the licensee's sale of the co-product HF acid.
Alternatives to the Proposed Action: The alternative to the
proposed action is for NRC not to amend the license to allow the sale
of HF acid. If the amendment is not approved, SPC would not be able to
sell the HF acid co-product. In that case, SPC would continue to
discharge fluoride to the Richland sewer. While this would eliminate
any potential risk to human health and safety, due to the trace amount
of uranium in the HF acid, there would be a continued burden on the
environment because of the disposal of the fluoride via the sewer, and
it would delay SPC's schedule for ultimate closure of the on0site
lagoons.
SPC could use alternative management methods for the HF acid,
including storage, treatment, and/or disposal. However, due to its
corrosive liquid nature, the acid is not suitable for disposal without
treatment. If the HF acid was considered to be a waste product, it
would be a dangerous waste as defined by the Washington Dangerous Waste
Regulations. However, HF acid is a commercial chemical product, and the
HF acid co-product from SPC's dry conversion process is suitable for
reuse as a substitute for virgin HF acid.

Finding of No Significant Impact: The NRC has prepared an
Environmental Assessment related to the amendment of Special Nuclear
Material License SNM-1227 to allow the sale of HF acid meeting the 3
pCi/ml limit. On the basis of this assessment, NRC has concluded that
environmental impacts that would result from the proposed licensing
action would not be significant and do not warrant the preparation of
an Environmentally Impact Statement. Accordingly, it has been
determined that a Finding of No Significant Impact is appropriate.
The Environmental Assessment and the documents related to this
proposed action are available for public inspection and copying at
NRC's Public Document Room at the Gelman Building, 2120 L Street NW,
