How VTR is Fueled
Fuel to Power Innovation
The Versatile Test Reactor (VTR) will be the nation’s only large-scale, advanced fast-neutron source for endurance testing of nuclear fuels, sensors and materials. The 300-megawatt (thermal) reactor will produce roughly 100 times the neutron flux and 20 times the neutron damage rate of current water-cooled research/test reactors. To produce these fast neutrons, VTR will require special fuel designed to meet research specifications while also operating safely and efficiently. VTR will not produce electricity.

The “driver fuel” (the fuel that powers the reactor) is a metallic fuel alloy of uranium, plutonium and zirconium (U-20Pu-10Zr) — a combination necessary to generate large numbers of fast neutrons.
