DEPARTMENT OF ENERGY


Proposed Subsequent Arrangement

AGENCY: National Nuclear Security Administration, Department of Energy.

ACTION: Proposed subsequent arrangement.

-----------------------------------------------------------------------

SUMMARY: This document is being issued under the authority of the 
Atomic Energy Act of 1954, as amended. The Department is providing 
notice of a proposed subsequent arrangement under Article 6 paragraph 2 
of the Agreement for Cooperation Between the Government of the United 
States of America and the Government of the Kingdom of Norway 
Concerning Peaceful Uses of Nuclear Energy.

DATES: This subsequent arrangement will take effect no sooner than 
January 9, 2023.

FOR FURTHER INFORMATION CONTACT: Ms. Andrea Ferkile, Office of 
Nonproliferation and Arms Control, National Nuclear Security 
Administration, Department of Energy. Telephone: 202-586-8868 or email: 
[email protected].

SUPPLEMENTARY INFORMATION: This subsequent arrangement concerns the 
alteration in form or content of U.S.-obligated nuclear material: (A) 
unirradiated uranium in the form of fuel pellets and grinding 
discharges in the amount and composition of 321.5 grams of U-235 in 
unirradiated highly enriched uranium (HEU) between 90-93 percent 
enrichment, and 143.8 grams of plutonium; and (B) irradiated uranium in 
the form of spent fuel rods in the amount and composition of 2,935 
grams irradiated HEU (containing a total of 1,838.4 grams of U-235 and 
625.2 grams of U-233 and whose pre-irradiation U-235 enrichments were 
between 90-93 percent) that is combined with 98,371 grams of thorium 
and 0.5 grams of plutonium. The Institute for Energy Technology (IFE), 
located in Kjeller, Norway, will downblend the irradiated HEU-
containing material identified above so as to result in an enrichment 
level of 3.5% in the isotope U-235 and in the combined isotopes U-235 
plus U-233. The remainder of the HEU (along with other U.S.-obligated 
nuclear materials, including 9,809 grams of unirradiated low-enriched 
uranium, 256 grams of natural uranium, 77 grams of depleted uranium, 
7,886 grams of thorium, and the 143.8 g of unirradiated plutonium) 
contained in unirradiated scrap material and grinding discards also 
will be processed in the same manner. The final form of the U.S.-
obligated nuclear material will be a metallic alloy, comprising the 
uranium, plutonium, and thorium together with additives such as 
stainless steel, depleted uranium, and reductants, in the form of 
cylindrical ingots, and will be stored at IFE. The processed U.S.-
obligated nuclear material will remain subject to the Agreement for 
Cooperation Between the Government of

the United States of America and the Government of the Kingdom of 
Norway Concerning Peaceful Uses of Nuclear Energy until Norway and the 
United States have agreed it is no longer useable for any nuclear 
activity relevant from the point of view of safeguards and it is 
finally disposed at a national disposal facility for radioactive waste.
    Pursuant to the authority in section 131a. of the Atomic Energy Act 
of 1954, as delegated, I have determined that this proposed subsequent 
arrangement concerning the alteration in form or content of the U.S.-
obligated nuclear material will not be inimical to the common defense 
and security.

Signing Authority

    This document of the Department of Energy was signed on December 
19, 2022, by Corey Hinderstein, Deputy Administrator for Defense 
Nuclear Nonproliferation, pursuant to delegated authority from the
