Section 161(v) of the Atomic Energy Act of 1954 authorizes the
Department of Energy (DOE) to offer its services, for a fee, to
convert natural uranium into the enriched uranium used for fuel in
commercial reactors, and provides that DOE "shall" restrict its
enrichment of foreign-source uranium intended for use in domestic
facilities "to the extent necessary to assure the maintenance of a
viable domestic uranium industry." DOE has determined that the
domestic uranium industry has not been "viable" since 1983, and
that the imposition of restrictions on DOE's enrichment of foreign
uranium would not assure viability. Respondent domestic uranium
mining and milling companies filed suit against petitioners (DOE
and some of its officers and employees) in Federal District Court,
alleging that DOE's failure to impose restrictions on the
enrichment of foreign uranium for use in domestic facilities
constituted a violation of § 161(v). Respondents moved for summary
judgment based on this claim, arguing that two facts -- that the
domestic industry was not viable and that DOE imposed no
restrictions on enrichment of foreign uranium -- established their
entitlement to judgment as a matter of law under § 161(v).
Petitioners filed a cross-motion for summary judgment, contending
that § 161(v) did not require restrictions when those restrictions
would not serve the statutory goal of assuring the maintenance of a
viable domestic industry. The court entered summary judgment for
respondents, holding that the statute gave DOE no discretion to
determine not to impose restrictions if the domestic industry was
not viable. The Court of Appeals affirmed the judgment in relevant
part.
Held: Section 161(v) does not require DOE to restrict
the enrichment of foreign uranium where such restriction would not
achieve the statutory goal of "assur[ing] the maintenance of a
viable domestic uranium industry," for the statute ties the amount
of restriction to be imposed to the achievement of that goal. Pp.

JUSTICE BLACKMUN delivered the opinion of the Court.
Section 161(v) of the Atomic Energy Act of 1954,
as
amended, 78 Stat. 606, 42 U.S.C. § 2201(v), provides that the
Department of Energy (DOE) shall restrict its enrichment of
foreign-source uranium intended for use in domestic facilities "to
the extent necessary to assure the maintenance of a viable domestic
uranium industry." DOE has determined that the domestic uranium
industry has not been "viable" [
Footnote 1] since 1983, and that the imposition of
restrictions on the enrichment of foreign uranium would not assure
viability. In this case, we consider whether § 161(v) requires DOE
to restrict the enrichment of foreign uranium, irrespective of
Page 486 U. S. 665
whether such restriction would make the domestic industry
viable. We conclude that it does not.
I
In 1964, as part of its efforts to move the nuclear power
industry into the private sector, Congress enacted the Private
Ownership of Special Nuclear Materials Act (Act), Pub.L. 88-489, 78
Stat. 602, which amended the Atomic Energy Act of 1954 to permit
privately owned utilities operating nuclear reactors also to own,
for the first time, the uranium used for fuel in their reactors. At
the time of the statute's enactment, DOE's predecessor, the Atomic
Energy Commission (AEC), was the only entity in the world with the
facilities to convert natural uranium into the enriched uranium
used for fuel in commercial reactors. [
Footnote 2] In § 161(v), Congress accounted for this
de facto monopoly by authorizing the AEC to offer "toll
enrichment" services whereby utilities could obtain unenriched
uranium on the open market and have it enriched by the AEC for a
fee. It was to protect the uranium mining and milling industry from
foreign competition during the period of transition from a
Government-controlled market to an open one that Congress included
in § 161(v) the requirement that the AEC, in written "criteria,"
restrict its enrichment of foreign-source uranium for domestic use
"to the extent necessary to assure the maintenance of a viable
domestic uranium industry." [
Footnote 3]
Page 486 U. S. 666
The criteria initially established by the AEC provided that it
would enrich no foreign-source uranium for domestic use.
See 31 Fed.Reg. 16479 (1966). In 1974, expecting an
increase in the demand for uranium to match the anticipated
expansion in the commercial use of nuclear power, the AEC amended
the criteria and provided for the gradual elimination by the end of
1983 of restrictions on its enrichment of foreign-source uranium
for domestic use.
See 39 Fed.Reg. 38016 (1974). The
phase-out took place according to schedule, and DOE, which has
replaced AEC for these purposes, [
Footnote 4] has not reimposed restrictions on the
enrichment of foreign uranium.
The early optimistic forecast for the commercial use of nuclear
power turned gloomy in the late 1970's and early 1980's, and the
economic condition of the domestic uranium industry deteriorated.
Cancellations and delays in the construction of nuclear reactors
led to a drop in the demand for uranium, which, in turn, brought
about a precipitous decline in the
Page 486 U. S. 667
price of uranium ore. [
Footnote
5] The decline of the domestic uranium industry has also been
attributed to other developments in the national and international
markets. DOE lost its enrichment monopoly when two European
consortia and the Soviet Union began to supply enriched uranium
produced from foreign-source ore.
See 51 Fed.Reg. 3625
(1986). This allowed foreign uranium suppliers, who offered lower
prices, to compete successfully with domestic suppliers for the
business of the domestic utilities. Another competitive alternative
was the emergence of a secondary market in which domestic
utilities, bound by long-term contracts to purchase enrichment
services in excess of their needs, sold their enriched uranium to
other utilities at substantial discounts.
Ibid.
In 1983, § 170B was added to the Atomic Energy Act of 1954 to
improve Congress' ability to monitor the domestic uranium
industry's condition. 96 Stat. 2081, 42 U.S.C. § 2210b. This new
provision required the Secretary of Energy to promulgate criteria
for assessing the viability of the industry and to report to the
President and the Congress annually on the industry's viability.
DOE accordingly issued criteria, still in effect,
see 10
CFR pt. 761 (1988), which define viability largely in terms of
"the extent to which the domestic mining and milling uranium
industry will be capable, at any particular time, of supplying the
needs of the domestic nuclear power industry under a variety of
hypothetical conditions."
48 Fed.Reg. 45747 (1983). Applying
Page 486 U. S. 668
these criteria, DOE reported that the industry was viable in
1983, but that one year later it was no longer viable.
See
S.Rep. No. 100-214, p. 9 (1987) (noting no change in viability in
1985 and no change in prospect for industry's viability in
1986).
Shortly after the Secretary first reported that the industry was
not viable, he initiated a rulemaking to consider revising the
criteria governing DOE's restriction of enrichment services. 51
Fed.Reg. 3624-3632 (1986). In his notice of proposed rulemaking,
the Secretary specifically stated that, despite the depressed
condition of the domestic industry, he proposed not to restrict the
enrichment of foreign uranium because
"[i]mport restrictions on foreign uranium would not assure the
viability of the domestic mining
Page 486 U. S. 669
and milling industry."
Id. at 3627.
After receiving extensive comments, the Secretary adopted final
revised criteria that again did not include any restrictions on
enrichment.
See 10 CFR pt. 762 (1988). In response to
critical comments from the domestic uranium industry, the Secretary
explained:
"The plain language of the statute makes clear that restrictions
are not to be imposed automatically if the domestic industry is
non-viable, but only if they are needed to, and in fact, will
assure the maintenance of a viable domestic uranium industry."
51 Fed.Reg. 27134 (1986). Finding that the domestic industry's
problems were due to "[s]tructural weaknesses," particularly the
collapse in demand and the consequent inability of the market to
sustain a price for uranium that enabled the industry to recover
its cost of production, the Secretary concluded that restrictions
on enrichment would do nothing to cure those ills.
Id. at
27135. Moreover, the Secretary found that, because DOE had no
market power with respect to the provision of enrichment services,
it could not force its enrichment customers to use domestic
uranium.
Id. at 27138. The Secretary repeated his earlier
conclusion that restrictions on enrichment services "would not
assure the viability of the domestic mining and milling industry,"
id. at 27135, and, if anything, would be
"counterproductive," because such restrictions would send some
customers away, requiring DOE to impose heavier costs on the
remaining domestic suppliers.
Id. at 27136.
Before the Secretary had concluded that the industry was not
viable, and before he had initiated this latest rulemaking,
respondents, three domestic uranium mining and milling companies,
filed suit in the United States District Court for the District of
Colorado against DOE and some of its officers and employees,
petitioners here. [
Footnote 6]
Respondents alleged, among other things, that DOE's failure to
impose restrictions on the enrichment of foreign uranium for use in
domestic facilities constituted a violation of § 161(v). App.
10-15. Respondents moved for summary judgment based on this claim,
[
Footnote 7] arguing that two
facts -- that the domestic industry was not viable and that DOE
imposed no restrictions on enrichment of foreign uranium --
sufficed to establish their entitlement to judgment as a matter of
law under § 161(v). App. 27-28. Accepting respondents' two facts,
DOE submitted a cross-motion for summary judgment, arguing that §
161(v) did not require restrictions when those restrictions would
not serve the statutory goal of assuring the maintenance of a
viable domestic industry. App. 39.
The District Court entered summary judgment for respondents.
App. to Pet. for Cert. 22a. According to the court, the statute
gave DOE no discretion to determine not
Page 486 U. S. 670
to impose restrictions if the domestic industry was not viable.
In view of its determination that immediate injunctive relief was
necessary to remedy DOE's "continuing refusal to recognize its
obligations under 42 U.S.C. § 2201(v),"
id. at 22a-23a,
the District Court entered an order requiring DOE to limit its
enrichment of foreign uranium for domestic use to 25% of all
material enriched between June 6 and December 31, 1986; imposing a
total ban on enrichment of foreign uranium beginning January 1,
1987, and "continuing until the viability of the domestic uranium
industry is assured"; and calling for a rulemaking to be commenced
to determine whether "criteria less restrictive than those imposed
by this order would assure the maintenance of a viable domestic
uranium industry."
Id. at 23a.
DOE appealed to the United States Court of Appeals for the Tenth
Circuit. [
Footnote 8] That
court affirmed the District Court's judgment in relevant part. 825
F.2d 1430 (1987). The Court of Appeals found the language of §
161(v) unambiguous: the term "shall" indicated that the
restrictions were mandatory, and the phrase "to the extent
necessary to assure the maintenance of a viable domestic uranium
industry" indicated that DOE had discretion to
"determine how much restriction is required to assure viability,
but it cannot decide not to impose restrictions when the industry
is not viable."
825 F.2d at 1439. According to the Court of Appeals, the statute
clearly instructs that
"when domestic nonviability is determined, restrictions on
enrichment of foreign-source uranium must be imposed, and must
become increasingly aggressive, to the point of 10O% restriction,
until the domestic industry is rejuvenated and becomes viable."
Ibid.
Page 486 U. S. 671
At DOE's request, the Court of Appeals stayed its mandate
pending this Court's final disposition of DOE's petition for
certiorari. App. 4. We granted the writ. 484 U.S. 1003 (1988).
II
We begin by emphasizing that the question presented here is a
narrow one which comes to us as a challenge to the entry of summary
judgment. That judgment rests on a legal conclusion drawn from two
uncontested facts: that the domestic uranium industry was not
viable, and that DOE was imposing no restrictions on the enrichment
of foreign-source uranium for use in domestic facilities. On the
basis of these facts alone, the courts below determined that DOE
was violating the law, for they read § 161(v)
"to require the DOE to restrict enrichment of foreign uranium
whenever the domestic industry is not viable -- whether or not such
restriction would result in successful resuscitation of the uranium
industry."
825 F.2d at 1437. Therefore, neither DOE's underlying assessment
that the industry was not viable, nor its assessment that no amount
of restriction would assure the industry's viability, nor, indeed,
what it means to "assure the maintenance of a viable . . .
industry" are before us at this time for review. The only question
presented is whether, regardless of the effects restrictions would
have on the viability of the domestic industry, DOE
must
impose restrictions on the enrichment of foreign-source uranium
whenever the domestic industry is determined not to be viable.
In considering this narrow question of statutory interpretation,
we cannot agree with the Court of Appeals' conclusion that the
relevant language in § 161(v) is unambiguous. While respondents'
reading of the statute is not implausible, it is by no means the
only reading the language can bear. The statute requires DOE to
impose restrictions "to the extent necessary to assure the
maintenance of a viable domestic uranium industry." If some amount
of restriction would assure a viable domestic industry, there can
be no doubt that DOE is
required to impose restrictions.
The term "shall"
Page 486 U. S. 672
makes clear that, in such circumstances, DOE has no discretion
to decline to impose restrictions. But whether that mandate applies
when restrictions would not assure viability is not directly
addressed by the language of the statute. Indeed, we well might
infer from the language that the particular issue presented by this
case was not the focus of Congress' concern at the time the
relevant provision was enacted. We therefore look to Congress'
express purpose in imposing restriction requirements to determine
whether they apply here.
The purpose of the relevant provision could not be articulated
more clearly in the statutory language.
See United States v.
American Trucking Assns., Inc., 310 U.
S. 534,
310 U. S. 543
(1940) ("There is, of course, no more persuasive evidence of the
purpose of a statute than the words by which the legislature
undertook to give expression to its wishes"). Congress imposed
restriction obligations on DOE to satisfy a single goal: "to assure
the maintenance of a viable domestic uranium industry."
Both parties agree that this is the clear purpose behind the
provision, but they put it to different uses. Respondents contend
that the statute reveals that Congress made a policy determination
that imposing restrictions on the enrichment of foreign-source
uranium could
always assure the viability of the domestic
industry, and therefore commanded DOE to impose some restrictions
whenever the industry's viability was threatened or destroyed.
Respondents suggest that DOE's refusal to impose restrictions under
the circumstances presented in this case simply reflects DOE's
disagreement with Congress' policy judgment.
See also 825
F.2d at 1439 ("DOE's argument that this policy is not wise in the
present uranium market should be made to Congress, and not to the
courts").
DOE, in contrast, asserts that the clear congressional purpose
defines the proper limit of DOE's obligation: DOE is required to
impose restrictions to the extent necessary to serve
Page 486 U. S. 673
a particular goal, and if
no extent will serve that
goal, then DOE does not violate the statute by declining to impose
restrictions. Indeed, DOE suggests, to impose restrictions it knew
were incapable of serving the statutory goal would, in fact, be to
act outside its authority.
DOE's reading strikes us as the more natural one. [
Footnote 9] While the parties, on remand, can
argue over whether DOE properly determined that no amount of
restriction would assure viability, and, indeed, what it means to
assure viability, it seems strained to assert that, even if DOE
properly determined that no amount of restriction would assure the
viability of the industry, Congress nevertheless intended DOE to
impose restrictions that were somehow calculated to serve that
unattainable goal. [
Footnote
10] Indeed, it is impossible to ascertain
Page 486 U. S. 674
from the statute how DOE would calculate the extent of
restriction to be imposed under respondents' interpretation of the
statute. The only guidepost DOE has is the amount necessary to
assure the viability of the domestic industry.
See 825
F.2d at 1438 (interpreting the phrase "to the extent necessary to
assure the maintenance of a viable domestic industry" as
"inform[ing] the DOE of the
amount of restriction
required") (emphasis in original). Where DOE determines that no
such amount exists, it is without guidance in setting restrictions.
The determination of the courts below that DOE was barred from
enriching
any foreign-source uranium rests on the
assumption that the greater the restrictions, the more assured is
the domestic industry's viability. This assumption cannot be
grounded in the statutory language and, indeed, for the purpose of
this case's summary judgment status, we must accept DOE's assertion
that the assumption is false.
III
Because we conclude that Congress did not intend to force DOE to
impose enrichment restrictions where such restrictions would not
achieve the statutory goal they were intended to achieve, the
judgment of the Court of Appeals is reversed and the case is
remanded for further proceedings consistent with this opinion.
[
Footnote 11]
It is so ordered.
[
Footnote 1]
A purist might regard the word "viable" as misused in this
context. It nevertheless appears in the statute, and therefore,
inescapably, it and its variants are used throughout this opinion.
See H. Fowler, Modern English Usage 679 (2d ed.1965); W.
Follett, Modern American Usage 344-345 (1966).
[
Footnote 2]
"Enrichment," in this context, refers to the process whereby the
proportion of the fissionable isotope U-235 is increased from
approximately 1% to approximately 3%. Natural, unenriched, uranium
cannot be used to produce commercial electric power.
[
Footnote 3]
The relevant portion of § 161(v) states that the AEC is
authorized to offer toll enrichment services provided:
"That the Commission, to the extent necessary to assure the
maintenance of a viable domestic uranium industry, shall not offer
such services for source or special nuclear materials of foreign
origin intended for use in a utilization facility within or under
the jurisdiction of the United States. The Commission shall
establish criteria in writing setting forth the terms and
conditions under which services provided under this subsection
shall be made available including the extent to which such services
will be made available for source or special nuclear material of
foreign origin intended for use in a utilization facility within or
under the jurisdiction of the United States:
Provided,
That before the Commission establishes such criteria, the proposed
criteria shall be submitted to the Joint Committee [on Atomic
Energy], and a period of forty-five days shall elapse while
Congress is in session . . . unless the Joint Committee by
resolution in writing waives the conditions of, or all or any
portion of, such forty-five-day period."
42 U.S.C. §§ 2201(v).
[
Footnote 4]
In 1974, Congress enacted the Energy Reorganization Act of 1974,
88 Stat. 1233,
as amended, 42 U.S.C. § 5801
et
seq., which abolished the AEC.
See § 5814(a). The
functions of the AEC were divided between two regulatory bodies.
Its "licensing and related regulatory functions" were transferred
to the Nuclear Regulatory Commission. § 5841(f). All other
functions, including the enrichment services program, were
transferred to the Energy and Research and Development
Administration, § 5814(c), which later became DOE,
see §§
301 and 703 of Department of Energy Organization Act, 91 Stat. 577,
606, 42 U.S.C. §§ 7151(a) and 7293.
[
Footnote 5]
Between 1979 and 1986, the market price of uranium dropped from
$43.25 per pound to $17.00 per pound, which an industry report
suggests is well below the conventional United States producers'
average cost of production.
See Status of the Domestic
Uranium Mining and Milling Industry: The Effects of Imports,
Hearing before the Subcommittee on Energy Research and Development
of the Senate Committee on Energy and Natural Resources, 97th
Cong., 1st Sess., 148 (1981) (statement of Edison Electric
Institute reporting drop from 1979 to 1981); 51 Fed.Reg. 27136, n.
12 (1986) (reporting 1986 price). Apparently the market price has
remained low.
See Weekly Metals Prices, Financial Times,
June 8, 1988, p. 34, col. 1 (London ed.) (reporting price of $15.75
per pound).
[
Footnote 6]
Petitioners are John S. Herrington, the Secretary of Energy; F.
Clark Huffman, Sherry E. Peske, Philip G. Sewell, James W. Vaughn,
and Joseph F. Salgado, officers or employees of DOE sued in their
official capacities; and DOE itself. For convenience, petitioners
are referred to collectively as DOE.
[
Footnote 7]
In this motion, respondents also sought summary judgment on
their claim that the criteria that DOE promulgated pursuant to §
170B to assess viability were "fatally flawed." App. 27.
Petitioners later sought leave to withdraw this portion of their
motion without prejudice. This request was granted by the District
Court. App. to Pet. for Cert. 24a.
[
Footnote 8]
While the appeal was pending, Congress adopted a joint
resolution for continuing appropriations to provide funding for DOE
and other agencies. 100 Stat. 1783. Section 305 of the resolution
expressly authorizes DOE to enrich foreign uranium until the
present litigation is brought to final judgment. 100 Stat.
1783-210.
[
Footnote 9]
In addition to arguing that its interpretation of § 161(v) is
more reasonable, DOE maintains that, even if the two
interpretations are equally reasonable, its interpretation is
entitled to deference as a "permissible construction" of a statute
by the agency charged with the statute's administration.
See
Young v. Community Nutrition Institute, 476 U.
S. 974,
476 U. S. 980
(1986), quoting
Chevron U.S.A. Inc. v.
Natural Resources Defense Council, Inc.,
467 U. S. 837,
467 U. S. 843
(1984). Although respondents contend that DOE's interpretation of §
161(v) has not been consistent over the years, and is therefore not
entitled to deference,
see Brief for Respondents 34, it is
unclear whether DOE articulated, in advance of this litigation,
any interpretation of the statute's application to the
facts presented here. On July 29, 1986, more than one month after
the District Court had issued its order granting summary judgment,
DOE issued a final rulemaking, stating that it would continue to
refuse to impose enrichment restrictions "in order [in part] to
formally record DOE's interpretation of section 161(v)." 51
Fed.Reg. 27134, n. 4 (1986). Because we agree that DOE's reading of
§ 161(v) is the more plausible one, we need not consider whether
the manner in which DOE has articulated its interpretation should
affect the degree of deference it warrants.

S. 137,

[
Footnote 10]
Of course, DOE would be in a different position if Congress
expressly had required that restrictions be imposed whenever the
industry was not viable without tying the extent of restrictions to
be imposed to the achievement of a stated purpose. Were DOE
governed by such a statute, its disagreement with the wisdom of the
requirement would not give DOE the discretion to ignore it.
[
Footnote 11]
While DOE styled its response to respondents' motion for summary
judgment as a cross-motion for summary judgment as well as a
memorandum in opposition,
see App. 39, DOE's successful
opposition to respondents' motion is insufficient to establish that
it is entitled to summary judgment in its favor. All we have
resolved here is that the industry's nonviability does not
necessarily trigger an obligation to impose enrichment
restrictions. Whether DOE, in fact, has violated § 161(v) by
failing to impose restrictions is a question to be addressed, in
the first instance, on remand after an opportunity for presentation
of further evidence and further briefing.
