N2 - This summary details the feasibility of placing a conceptual fast spectrum test loop within the Advanced Test Reactor (ATR) at Idaho National Laboratory (INL) that would allow for preliminary Versatile Test Reactor (VTR)-condition testing. This experimental loop - the ATR Fast Spectrum Test Loop (FSTL) - has been designed, based on benchmarking, against predicted in-reactor conditions that the VTR will produce, including the use of molten sodium as a reactor coolant. A discussion of the mechanical design of the in-pile vehicle, along with the material delineation of primary components, is included. Furthermore, a general physical arrangement of the hardware necessary to compliment the FSTL in-pile vehicle to provide a sodium-cooled environment within the ATR, passing through the Large-I position, is discussed in detail.
