Energy discretionary budget authority
From the OMB Public Budget Database — clean, summable, and the figure to cite for an agency total. It is the whole of Energy's discretionary request, not a total of the parsed lines above, and this page never adds the two together.
What this funds
Explores the nature of matter — how protons, neutrons, and nuclei form and interact — through theory and accelerator-based user facilities, and supports the nuclear science workforce and research infrastructure.
Extracted from Energy Programs, p. 17. Verbatim; nothing here is paraphrased.
Ask this budget line
Answers come from the figures on this page and nothing else. These dollars are parsed from Energy's Congressional Justification and are approximate — confirm anything that matters against the cited page.
