Cancellation: SD 410.1A, Implementation of National Nuclear Security Administration Central Technical Authority Responsibilities Regarding Nuclear Safety Requirements
The responsibilities listed within SD 410.lA are now captured in other NNSA directives, including SD 450.2A, Functions, Responsibilities, and Authorities for Safety Management, and a recently developed Office of Safety, Infrastructure, and Operations (NA-50) standard operating procedure. Cancelling this directive eliminates potential confusion in implementing the CTA's nuclear safety responsibilities. Many of SD 410.lA's requirements are assigned to organizations that no longer exist and processes were written to support the Administrator or Principal Deputy Administrator when acting as the CTA.
