The Electric Power Research Institute (EPRI) Advanced Recycle Methodology Program (ARMP) has been validated against Cycle 1 measurements made on Commonwealth Edison Company's Zion Unit 2 PWR core. In addition to the usual reaction rate and axial trace measurements for determining power distributions, gamma-scan measurements were available to provide additional data to validate the ARMP model power shapes. Availability of the new ENDF/B-5 library, restricted here to beginning-of-life (BoL), provided this library's first integral reactor test. The EPRI ARMP PWR code sequence closely predicted measured fission detector reaction rate data and La140 gamma-scan data applicable to first cycle power distribution predictability. This code sequence was less successful in modeling power distributions near the reflector boundary than in the core interior. Use of the ENDF/B-5 library in ARMP at BoL resulted in a considerable improvement in reactivity prediction. 8 refs., 159 figs., 21 tabs.
