; and (B) establish a program to demonstrate not fewer than 2, and not more than 4 additional operational advanced reactor designs by not later than December 31, 2035. (2) Requirements In carrying out demonstration projects under paragraph (1), the Secretary shall— (A) include diversity in designs for the advanced nuclear reactors demonstrated under this section, including designs using various— (i) primary coolants; (ii) fuel types and compositions; and (iii) neutron spectra; (B) seek to ensure that— (i) the long-term cost of electricity or heat for each design to be demonstrated under this subsection is cost-competitive in the applicable market; and (ii) selected projects can meet the deadline established in paragraph (1) to demonstrate first-of-a-kind advanced nuclear reactor technologies, for which additional information shall be considered, including— (I) the technology readiness level of a proposed advanced nuclear reactor technology; (II) the technical abilities and qualifications of a team desiring to partner with the Department to demonstrate a proposed advanced nuclear reactor technology; and (III) the capacity to meet cost-share requirements of the Department; (C) ensure that each evaluation of candidate technologies for the demonstration project is completed through an external review of the proposed design, which shall be conducted by a panel that includes not fewer than 1 representative of each of— (i) an electric utility relevant to the intended initial deployment market; (ii) the local government of the intended initial deployment market; and (iii) an entity that uses high-temperature process heat for manufacturing or industrial processing, such as a petrochemical company, a manufacturer of metals, or a manufacturer of concrete, if applicable; (D) when applicable, enter into cost-sharing agreements with partners in accordance with section 988 for the conduct of activities relating to the research, development, and demonstration of private sector advanced nuclear reactor designs under the program
