1. Short title This Act may be cited as the Nuclear Energy Research Infrastructure Act of 2017 . 2. Versatile neutron source (a) In general The Secretary of Energy shall provide for a versatile reactor-based fast neutron source, which shall operate as a national user facility. The Secretary shall consult with the private sector, universities, National Laboratories, and relevant Federal agencies to ensure that the versatile neutron source is capable of meeting Federal research needs for neutron irradiation services. (b) Facility capabilities (1) Capabilities The Secretary shall ensure that the facility described in subsection (a) will provide, at a minimum, the following capabilities: (A) Fast neutron spectrum irradiation capability. (B) Capacity for upgrades to accommodate new or expanded research needs. (2) Considerations In carrying out paragraph (1), the Secretary shall consider the following: (A) Capabilities that support experimental high-temperature testing. (B) Providing a source of fast neutrons at a neutron flux higher than that at which existing research facilities operate, sufficient to enable research for an optimal base of prospective users. (C) Maximizing irradiation flexibility and irradiation volume to accommodate as many concurrent users as possible. (D) Capabilities for irradiation with neutrons of a lower energy spectrum. (E) Multiple loops for fuels and materials testing of different coolants. (F) Capabilities that support irradiating and processing targets for isotope production. (G) Additional pre-irradiation and post-irradiation examination capabilities. (H) Lifetime operating costs and lifecycle costs. (c) Start of operations The Secretary shall, to the maximum extent practicable, ensure that the start of full operations of the facility under this section occurs before December 31, 2025. (d) Funding Out of funds appropriated to the Office of Nuclear Energy, there shall be made available to the Secretary to carry out activities, including design and construction of the facility, under this
