Radioactive-nuclide decay data in science and technology

Description: The scope of ENDF/B has recently been expanded to include radioactive- nuclide decay data. In this paper, the content and organization of the decay data which are included in ENDF/B are presented and discussed. The application of decay data in a wide variety of nuclear-related activities is illustrated by a number of examples. Two items pointed up by the ENDF/B decay-data compilation effort are treated: the identification of deficiencies in the data; and the importance of a radioactive-nuclide … more

Measured data used in the Watusi cross-section sets

Description: In this document we list the experimental data that were used to make up the major cross- section sets that we use in the Watusi code to calculate the amount of detector activation in device tests. In order to use experimental data to make up a cross-section set, it is often necessary to extrapolate the cross sections down to either the threshold energy or to 0.01 keV, and to extrapolate up to 20 MeV. We then fit the data to a function so that we can get a smoothed set of interpolated values at… more

A temperature dependent ENDF/B-VI, release 4: Cross Section Library

Description: The ENDF/B data library has recently been updated and is now available through the National Nuclear Data Center (NNDC), Brookhaven National Laboratory. This most recent library is identified as ENDF/B- VI, Release 4. This release completely supersedes the preceding release, Release 3, distributed in January 1996. As distributed the ENDF/B-VI, Release 4 data includes cross sections represented in the form of a combination of resonance parameters and/or tabulated energy dependent cross sections, … more

Status of Current Plutonium Evaluations And an Update Plan for ENDL99

Description: We review the current state of ENDL99, ENDF/B-VI.r8, JENDL-3.3, JEFF-3.0 and ENDF/B-VII.{beta}0 plutonium evaluations and lay out a tentative plan for updating all of the ENDL99 plutonium evaluations. In some specific cases, an evaluation for a particular isotope is of sufficient quality for us to adopt in ENDL99. More often, the quality of all evaluations for an isotope are low enough that we will need to perform a new evaluation.

Alternative Approach to Nuclear Data Representation: Building the infrastructure to support QMU and next-generation simulations

Description: The nuclear data infrastructure currently relies on punch-card era formats designed some five decades ago. Though this system has worked well, recent interest in non-traditional and complicated physics processes has demanded a change. Here we present an alternative approach under development at LLNL. In this approach data is described through collections of distinct and self-contained simple data structures. This structure-based format is compared with traditional ENDF and ENDL, which can rough… more
