On 2 August 2013 the Department of Energy (DOE) published a supplemental notice of proposed rulemaking (SNOPR) in the Federal Register (78 Fed. Reg. 48629) to amend the Part 810 Regulations (10 C.F.R. Part 810), which govern the export and re-export of unclassified nuclear technology and assistance. This latest notice proposes, with some changes, a rule that DOE originally proposed almost two years ago (76 Fed. Reg. 55278, 7 September 2011).
