SUPPLEMENTARY INFORMATION:

This proposed subsequent arrangement concerns the granting of advance consent to Canada, pursuant to paragraph D of Article XII of the Agreement, to retransfer unirradiated source material, unirradiated uranium enriched to less than 20% in the isotope U-235, and moderator material to member states of the European Atomic Energy Community (EURATOM), and to the United Kingdom of Great Britain and Northern Ireland (UK). Any such material transferred from Canada to EURATOM would be made subject to the Agreement for Cooperation in the Peaceful Uses of Nuclear Energy between the United States of America and the European Atomic Energy Community (the U.S.-EURATOM 123 Agreement). Any such material transferred from Canada to the UK prior to the entry into force of the Agreement between the Government of the United States of America and the Government of the United Kingdom of Great Britain and Northern Ireland for Cooperation in Peaceful Uses of Nuclear Energy (the U.S.-UK 123 Agreement) would be made subject to the U.S.-EURATOM 123 Agreement, and any such material transferred from Canada to the UK following the entry into force of the U.S.-UK 123 Agreement would be made subject to the U.S.-UK 123 Agreement.

Pursuant to the authority in section 131 a. of the Atomic Energy Act of 1954, as delegated, I have determined that this proposed subsequent arrangement will not be inimical to the common defense and security of the United States of America.
