Current State of the Design Engineering of the Versatile Test Reactor Plant

With the Nuclear Energy Innovation Capabilities Act of 2018, launched in March 2019, the Congress of the United States authorized funding to design and build a Versatile Test Reactor (VTR). This paper describes the current state of the design, a snapshot, of the key systems that the VTR will rely upon to achieve its mission of irradiating a wide variety of fuels, materials, instruments, and sensors with fast neutrons at a high neutron flux.
