New Resolved Resonance Region Evaluation for 63,65Cu for Nuclear Criticality Safety Program
Vladimir Sobes,Vladimir Sobes,Luiz C Leal,Klaus H Guber,Benoit Forget,Stefan Kopecky,Peter Schillebeeckx,P. Siegler +7 more
TL;DR: In this paper, a new resolved resonance region evaluation of 63Cu and 65Cu was done in the energy region from 10-5 eV to 99.5 keV using the Reich-Moore approximation.
Comparative analysis of nuclear cross sections in monte carlo methods for medical physics applications
TL;DR: In this article, the authors compared the data used in two Monte Carlo (MC) codes (EGSnrc and MCNPX) and found that much less central processing unit (CPU) time is required by the EGSnrc code for simulations involving large numbers of particles, primarily electrons.
Journal ArticleDOI
Resonance structure in the fission of (235U + n)
TL;DR: In this paper, a multilevel reduced R-matrix analysis of the neutron-induced resonance cross sections of /sup 235/U has been carried out using the angular anisotropy measurements of Pattenden and Postma, obtaining a Bohr-channel representation of the resonances in a two-fission vector space for each spin state.

TL;DR: OECD Nuclear Energy Agency's working party assesses nuclear data improvement needs and addresses these needs by initiating joint activities in the framework of dedicated WPEC subgroups, which include two subgroups on improved fission product yield evaluation methodologies and on modern nuclear database structures.
Journal ArticleDOI
Parameterized representation of macroscopic cross section for PWR reactor
TL;DR: In this article, a parameterized representation of the homogenized macroscopic cross section for PWR fuel element as a function of soluble boron concentration, moderator temperature, fuel temperature, moderator density and U92235 enrichment is presented.
