The CIELO collaboration has studied neutron cross sections on nuclides that significantly impact criticality in nuclear technologies - 235,238U, 239Pu, 56Fe, 16O and 1H with the aim of improving accuracy data resolving previous discrepancies our understanding. This multi-laboratory pilot project, coordinated via OECD/NEA Working Party Evaluation Cooperation (WPEC) Subgroup 40 support also from IAEA, motivated experimental theoretical work led to suites new evaluated libraries accurately...
The neutron microscopic capture cross section for 235U is a critical parameter the design and operation of nuclear reactors. evaluated data libraries ENDF/B-VII.1 JENDL-4.0 have nearly identical values energies below 0.5 keV. In most recent release JENDL library onset unresolved resonance region was changed from 2.25 keV to energy 1.5 average about 10% higher than that JENDL-4.0. an attempt address discrepancies between libraries, measurement conducted at Gaerttner LINAC Center located...
A new array of four Deuterated Benzene (${\mathrm{C}}_{6}{\mathrm{D}}_{6}$) detectors has been installed at the Gaerttner Linear Accelerator Center Rensselaer Polytechnic Institute for purpose measuring neutron capture cross sections in keV region. Measurements were performed on samples $^{181}\mathrm{Ta}$ unresolved resonance region (URR) using a filtered-beam technique, by which 30 cm iron filter was placed white-spectrum beam to remove all time-dependent $\ensuremath{\gamma}$-ray...
Accurate isotopic molybdenum nuclear data are important because can exist in reactor components including fuel, cladding, or as a high yield fission product. High-resolution time-of-flight neutron transmission measurements on highly enriched metallic samples of $^{95}\mathrm{Mo}$, $^{96}\mathrm{Mo}$, $^{98}\mathrm{Mo}$, and $^{100}\mathrm{Mo}$ were performed the resonance energy range from 1 to $620\phantom{\rule{0.16em}{0ex}}\mathrm{keV}$. The taken with newly developed modular...
A new array of C6D6 detectors installed at the RPI LINAC Center has enabled capability to measure neutron capture cross sections above 847 keV inelastic scattering threshold 56Fe through use digital post-processing filters and pulse-integral discriminators, without sacrificing statistical quality data lower incident energies where such filtering is unnecessary. The were used perform time-of-flight section measurements on a sample 99.87% enriched iron-56. total-energy method, combined with...
The Gaerttner LINAC Center at RPI uses a 60 MeV electron linear accelerator to produce short pulses of neutrons with duration 5-5000 ns. main research thrust the is nuclear data for reactors and criticality safety applications. includes several setups time-of-flight measurements including neutron transmission, capture scattering detectors, lead slowing-down spectrometer. Experiments were designed interaction cross sections that cover energy range 0.01 eV 20 MeV. Recently added experiments...
