SUPPLEMENTARY INFORMATION:

This subsequent arrangement concerns the alteration in form or content of 1.3 kg of U.S.-origin highly enriched uranium (HEU), 1.21 kg of which is in the isotope of U-235 (93 percent enrichment) and currently located at PT Industri Nuklir (PT INUKI) in Serpong, Indonesia, through down-blending to reduce its enrichment to less than 20 percent U-235. The purpose of the down-blending of the HEU is to achieve permanent threat reduction by eliminating HEU from Indonesia. PT INUKI will down-blend the HEU contained in 514 bottles of irradiated HEU targets in liquid form and 14 containers of un-irradiated liquid HEU used in the plating process for medical isotope production, on-site at the Pusat Penelitian Ilmu Pengetahuan dan Teknologi facility in Serpong. The quantity of uranium will increase from 1.3 kg to 6.72 kg while the U-235 enrichment will decrease from 93 percent to 18 percent. The down-blend operation is scheduled to last for approximately three months.

In accordance with section 131a. of the Atomic Energy Act of 1954, as amended, it has been determined that this subsequent arrangement concerning the alteration in form or content of nuclear material of United States origin will not be inimical to the common defense and security of the United States of America.
