The ZPPR-17 assembly was part of the JUPITER-III cooperative program between the US DOE and PNC of Japan. The assembly was designed to study the neutronic behavior of a large, axially heterogeneous, liquid-metal-cooled reactor. The unique feature of the assembly was an internal blanket region in the axial center of the core extending two-thirds of the core radius. Assembly variants with 25 control rod positions and with 13 half-inserted control rods were built. This report describes in detail the results of measurements and analyses of ZPPR-17. The measurements emphasized reaction rate distributions, and gamma dose measurements were included. Additional measurements were control worth, sodium void worth, and reactivity coefficients associated with small material motions in assembly expansion and bowing
