‘‘(5) ADJUSTMENTS TO IMPORT LIMITATIONS.— 
‘‘(A) IN
GENERAL.—The import limitations described 
in paragraph (2)(A) are based on the reference data in 
the 2005 Market Report on the Global Nuclear Fuel Market 
Supply and Demand 2005–2030 of the World Nuclear 
Association. In each of calendar years 2016 and 2019, the
H. R. 2638—77 
Secretary of Commerce shall review the projected demand 
for uranium for nuclear reactors in the United States and 
adjust the import limitations described in paragraph (2)(A) 
to account for changes in such demand in years after the 
year in which that report or a subsequent report is pub-
lished. 
‘‘(B) INCENTIVE ADJUSTMENT.—Beginning in the second 
calendar year after the calendar year of the completion 
of the Russian HEU Agreement, the Secretary of Energy 
shall increase or decrease the amount of low-enriched ura-
nium that may be imported in a calendar year under para-
graph (2)(B) (including the amount of low-enriched uranium 
that may be imported for each kilogram of highly enriched 
uranium downblended under paragraph (2)(B)(i)) by a 
percentage equal to the percentage increase or decrease, 
as the case may be, in the average amount of uranium 
loaded into nuclear power reactors in the United States 
in the most recent 3-calendar-year period for which data 
are available, as reported by the Energy Information 
Administration of the Department of Energy, compared 
to the average amount of uranium loaded into such reactors 
during the 3-calendar-year period beginning on January 
1, 2011, as reported by the Energy Information Administra-
tion. 
‘‘(C) PUBLICATION OF ADJUSTMENTS.—As soon as prac-
ticable, but not later than July 31 of each calendar year, 
the Secretary of Energy shall publish in the Federal Reg-
ister the amount of low-enriched uranium that may be 
imported in the current calendar year after the adjustments 
under subparagraph (B). 
‘‘(6) AUTHORITY FOR ADDITIONAL ADJUSTMENT.—In addition 
to the adjustment under paragraph (5)(A), the Secretary of 
Commerce may adjust the import limitations under paragraph 
(2)(A) for a calendar year if the Secretary— 
‘‘(A) in consultation with the Secretary of Energy, 
determines that the available supply of low-enriched ura-
nium and the available stockpiles of uranium of the Depart-
ment of Energy are insufficient to meet demand in the 
United States in the following calendar year; and 
‘‘(B) notifies Congress of the adjustment not less than 
45 days before making the adjustment. 
‘‘(7) EQUIVALENT QUANTITIES OF LOW-ENRICHED URANIUM 
IMPORTS.— 
‘‘(A) IN
GENERAL.—The import limitations described 
in paragraphs (1) and (2) are expressed in terms of uranium 
containing 4.4 percent uranium-235 and a tails assay of 
0.3 percent. 
‘‘(B) ADJUSTMENT
FOR
OTHER
URANIUM.—Imports of 
low-enriched uranium under paragraphs (1) and (2), 
including low-enriched uranium obtained under contracts 
for separative work units, shall count against the import 
limitations described in such paragraphs in amounts cal-
culated as the quantity of low-enriched uranium containing 
4.4 percent uranium-235 necessary to equal the total 
amount of uranium-235 contained in such imports.

NIUM.—For purposes of determining the additional low- 
enriched uranium imports allowed under paragraph (2)(B), 
highly 
enriched 
uranium 
not 
of 
weapons 
origin 
downblended pursuant to subparagraph (A) shall count 
as downblended highly enriched uranium of weapons origin 
in amounts calculated as the quantity of highly enriched 
uranium containing 90 percent uranium-235 necessary to 
equal the total amount of uranium-235 contained in the 
highly 
enriched 
uranium 
not 
of 
weapons 
origin 
downblended pursuant to subparagraph (A).

shall be construed to modify the terms of the Russian 
HEU Agreement, including the provisions of the Agreement 
relating to the amount of low-enriched uranium that may 
be imported into the United States. 
‘‘(B) OTHER AGREEMENTS.—If a provision of any agree-
ment between the United States and the Russian Federa-
tion, other than the Russian HEU Agreement, relating 
to the importation of low-enriched uranium, including low- 
enriched uranium obtained under contracts for separative 
work units, into the United States conflicts with a provision 
of this section, the provision of this section shall supersede 
the provision of the agreement to the extent of the conflict.’’.
