From the Executive Summary: "Under the Atomic Energy Act of 1954, as amended, the Defense Nuclear Facilities Safety Board (DNFSB or Board) is charged with providing independent safety oversight of the Department of Energy's (DOE) defense nuclear facilities complex--a complex with the mission to design, manufacture, test, maintain, and decommission nuclear weapons, as well as other national security priorities. The act mandates that the Board review the content and implementation of DOE standards, facility and system designs, and events and practices at DOE defense nuclear facilities to provide independent analysis, advice, and recommendations to inform the Secretary of Energy regarding issues of adequate protection of public health and safety at DOE defense nuclear facilities. The Board prioritizes its safety oversight activities based on risk to the public and workers, types and quantities of nuclear and hazardous material at hand, and hazards of the operations involved. This annual report summarizes the Board's significant safety oversight initiatives and some high-priority safety issues at defense nuclear facilities subject to the Board's oversight during 2021."
