SD 226.1-2, Defense Nuclear Security Governance, Cancellation Memo
In accordance with NNSA SD 251.1 B, Directives Management, all NNSA directives must be reviewed and recertified for relevancy every three years. NA-70 reviewed SD 226.1-2 and determined that its requirements, roles and responsibilities were implemented by the NNSA SD 226.1 C, NNSA Site Governance, and not needed. Cancellation of SD 226.1-2 would have no impact on Safeguards and Security oversight of NNSA laboratories, plants, and sites and would eliminate an unnecessary directive.
