TL;DR: In this article, a detailed three-dimensional continuous energy MCNP4B model of the LWR-PROTEUS critical facility has been developed for the analysis of whole-reactor characteristics using ENDF/B-V, ENDF-B-VI and JEF-2.2 cross-section sets.

TL;DR: In this article, high-resolution gamma spectroscopy was performed on individual fuel rods of a fresh, highly heterogeneous Boiling Water Reactor (BWR) fuel assembly, after irradiation at low power in the PROTEUS reactor at PSI, to determine the ratio of neutron captures in 238U (C8) to total fissions (Ftot).

TL;DR: In this article, the reaction rate distributions measured with a special gamma-scanning machine employing twin germanium detectors were validated using the experimental results of the LWR-PROTEUS Phase I project corresponding to full-density water moderation conditions (core 1 B).

TL;DR: In this paper, accurate critical experiments have been performed for the validation of total fission (Ftot) and 238U-capture (C8) reaction rate distributions obtained with CASMO-4, HELIOS, BOXER, and MCNP4B for the lower axial region of a real Westinghouse SVEA-96 + fuel assembly.

TL;DR: In this paper, a measurement station has been built for the non-destructive investigation of burnt fuel rod segments through high-resolution gamma spectrometry, and four UO2 pressurised water reactor fuel rod segment with different burnup levels between 50 and 100GWd/t and 10 year cooling time have been experimentally characterised using gamma-ray spectrometer to determine 134Cs, 137Cs and 154Eu and their corresponding concentration ratios.
