![]() The new evaluation results in a slight decrease of the effective capture resonance integral and improves the prediction of integral thermal benchmarks by 70 pcm to 200 pcm.Ī special 360° deflection magnet has been installed at the exit of the 150 MeV Geel Electron Linear Accelerator (GELINA). ![]() ![]() A description is given of the statistical properties of the resonance parameters and of the recommended values of the average parameters. ![]() The neutron transmissions and the capture cross sections calculated with the resonance parameters are compared with the experimental data. The experimental database and the method of analysis are described in this report. Compared with previous evaluations, the energy range for this resonance analysis was extended from 10 to 20 keV, taking advantage of the high resolution of the most recent ORELA transmission measurements. The neutron resonance parameters of ²³â¸U were obtained from a SAMMY analysis of high-resolution neutron transmission measurements and high-resolution capture cross section measurements performed at the Oak Ridge Electron Linear Accelerator (ORELA) in the years 1970-1990, and from more recent transmission and capture cross section measurements performed at the Geel Linear Accelerator (GELINA).
