Status report of the WPEC/Subgroup-22
نویسنده
چکیده
The subgroup-22 was formed 4 years ago to investigate nuclear data to improve the keff prediction of thermal benchmarks which are significantly underestimated by the most recent nuclear data libraries. This paper summarizes the evaluation work performed at several laboratories [Oak Ridge National Laboratory (ORNL), Los Alamos National Laboratory (LANL), Commissariat a l’énergie atomique de Bruyeres-Le-Chatel (CEABRC), International Atomic Energy Agency (IAEA)] as well as the integral tests (mainly at LANL, Knoll Atomic Power Laboratory (KAPL), Bettis Atomic Power Laboratory (BAPL), Nuclear Research and Consultancy Group NRG-Petten, CEA and IAEA) of the successive versions of the new evaluated files. The mandate of the subgroup-22 is ending this year and a final report is in preparation.

Review of capture cross section data in support to WPEC Subgroup 31
This report is the result of the EC-JRC-IRMM support to the OECD-NEA WPEC Subgroup 31, " Meeting Nuclear Data Needs for Advanced Reactor Systems ". It summarizes the contribution that is related to capture cross section data. The status of capture cross section measurements based on the detection of prompt γ-rays is discussed and experimental data that are available to evaluate the capture cros...
متن کاملStatus Report on the WPEC / Subgroup A Activities in 2004 - 2005
The primary goal of the long-term Subgroup A is to promote collaboration and exchange among nuclear reaction code developers internationally. This document reports on the Subgroup A activities in 2004-2005, both in view of individual codes (TALYS, EMPIRE, GNASH/McGNASH) development, and in regard to the common development of the ModLib library. Notably, several important new code releases were ...
متن کاملWPEC Subgroup Proposal
The cross sections of 235U were examined by WPEC Subgroup 18 focusing on the thermal and epithermal energy region. As a result, the ORNL group evaluated resolved resonance parameters of 235U up to 2.25 keV, which are currently used for all major libraries. Using the resolved resonance parameters, prediction accuracy of neutronic characteristics is satisfactory for thermal reactors. However, rec...

We sought to characterize WPEC by quantifying per-hour log-fold change. To do so, we regressed the log gene expression on time (hour) and extracted the linear slope. For genes with monotonically increasing or decreasing expression trajectories, the utility of our WPEC measure to discriminate is obvious. Our WPEC measure can also discriminate with more complex trajectories which may be reflectiv...
متن کاملDetection of avian leukosis virus subgroup J in albumen of commercial and native fowl eggs using RT-PCR in Fars province of Iran
The subgroup J of ALV (ALV-J) has emerged as an important pathogen of meat-type chickens since1989. This virus is responsible for economic losses due to both mortality and depressed performance inchickens. So, the objective of this study is the detection of ALV-J in the albumen of commercial and nativefowl eggs using RT-PCR. Three hundred and seventy egg albumens were randomly selected from dif...
