The Zero Power Physics Reactor (ZPPR) fast critical facility at the Argonne National Laboratory-West site in Idaho was built in 1969 to obtain neutron physics information necessary for the design of fast breeder reactors. The ZPPR-15 phases A through D were intended to model a 330 MWt Integral Fast Reactor (IFR) concept. This work focuses on foil measurements in the shielding regions of ZPPR-15B. The ZPPR-15B core simulated an equilibrium cycle U-Pu-Zr fuel core where plutonium created in the blankets was sufficient to negate the need for enriched {sup 235}U feedstock. ZPPR-15B consisted of an inner core zone, an outer core zone of higher fissile content, a thin radial blanket and a thick steel reflector. The inner and outer core zones were of approximately equal volumes and were designed to simulate a sodium-cooled, metal-fueled fast reactor with approximately 10 wt.% zirconium in the target fuel composition. Consistent with the IFR program, ZPPR-15B had Zr plates in the inner core region to simulate a Zr alloyed fuel composition. The outer core had no Zr plates due to the limited inventory of Zr plates and thus consisted of drawers which had stainless steel plates rather than Zr. (authors)
