This report documents the verification of EPRI's ARROTTA space-time kinetics computer program against a similar industry code. A three-dimensional space-time kinetics calculation of a PWR rod ejection transient was run using the ARROTTA code. The results were compared against those of Combustion Engineering's HERMITE code. The transient used an initial zero power condition and ejected a rod worth of $1.16. Additionally, steady state cases were compared in support of the transient analysis problem definition. Excellent agreement was obtained in all phases of the comparison including steady state and transient total core power, peak assembly power, core average fuel temperature, and maximum fuel temperature. A complete problem description, including all of the input, is contained in an appendix.
