Abstract

Results are presented for the ZPPR-15B, 15C and 15D assemblies. These assemblies were part of the IFR Physics Test Program to provide modern integral physics data for metallic-fuelled LMRs. The ZPPR-15B assembly had a ternary fuel alloy of plutonium, depleted uranium and zirconium. In ZPPR-15C, about half of the fuel elements were converted to {sup 235}U fuel, while in ZPPR-15D about 90% of the fuel was {sup 235}U. Results from ZPPR-15D include foil reaction rates, control rod worths, sodium void worths, gamma ray dose distributions and noise coherence measurements. Multigroup cross section data processing and calculation models are presented for the assemblies containing {sup 235}U fuel.
