The Versatile Test Reactor (VTR) program is aiming at designing and building an advanced test reactor in the U.S. within 10 years. This reactor will bridge the current capability gap in irradiation capabilities, effectively supporting development of all types of advanced reactors through enabling accelerated material and fuel testing. At this stage, the VTR is a 300 MWth sodium-cooled fast reactor using metallic fuel bearing plutonium. It allows achieving fast flux in excess of 4x1015 n/cm2, offers very large irradiation volumes, and permit concurrent use of up to four coolant types through the cartridge loops. The state of the project, its origin, and an overview of the design activities will be discussed.
Dr. Florent Heidet is a principal nuclear engineer and manager of the Advanced Nuclear Energy Systems group at Argonne National Laboratory. Florent’s interest is in development of advanced nuclear reactors and enabling their construction. He is the manager for the core design activities of the Versatile Test Reactor, and the Argonne program manager for the Transformational Challenge Reactor. Florent has also initiated the modeling & simulation and analysis activities related to Molten Salt Reactor at Argonne. He obtained his Ph.D. from UC Berkeley in 2010.
