Nuclear Industrial Base Act This bill requires the Department of Energy (DOE) to establish the Nuclear Industrial Base Analysis and Sustainment Program. A nuclear industrial base means the persons or organizations within the federal government and the private sector that are engaged in designing, producing, maintaining, developing, or integrating nuclear energy systems, components, parts, or other assets. In carrying out the program, DOE must monitor and assess the needs of the nuclear industrial base, support partnerships to develop and deploy new nuclear power assets, and make recommendations to address supply chain vulnerabilities of such base.
