Riepilogo

The U.S. Nuclear Regulatory Commission (NRC) is issuing a revised environmental assessment (EA) and finding of no significant impact (FONSI) for an exemption request submitted by Louisiana Energy Services, LLC (LES) also doing business as (dba) Urenco USA (UUSA), that would allow UUSA, a general licensee and certificate of compliance (CoC) user, to use a vendor's transportation package design (CoC No. 9362) for transport of certain limited shipments of uranium hexafluoride (UF 6 ) up to 10 weight (wt.) percent enrichment of uranium-235 (U-235), a higher enrichment than authorized in CoC No. 9362, Revision No. 5. This EA includes revisions to account for a change in the proposed exemption that would not result in changes to the potential environmental impacts.
