H.R. 8159 proposed to create greater DOE authority over the NNSA
"The bill clarifies that NNSA officers and employees shall be responsible to and subject to the authority, direction and control of the Secretary of Energy. It further strikes a provision from Section 3220 barring DOE personnel other than the Secretary from exercising authority, direction, or control over personnel employed by or contracting with NNSA."
