RSIC COMPUTER CODE PSR-015
1. NAME AND TITLE
UKE-III: Cross Section Format Translator - UKNDL to ENDF/B.
UKNDL Library for 241Am.
Computer Sciences Division at Oak Ridge National Laboratory, Oak Ridge, Tennessee.
3. CODING LANGUAGE AND COMPUTER
Fortran IV; IBM 360/91/75.
4. NATURE OF PROBLEM SOLVED
UKE is designed to translate neutron cross sections on computer tape from the United Kingdom Atomic Energy Authority (UKAEA) Nuclear Data Library (NDL) format to that of the Evaluated Nuclear Data File (ENDF/B). The code will translate UKAEA library smooth cross section data, secondary angular distributions, and secondary energy distributions to the ENDF/B format. The secondary angular distributions are translated as differential scattering probabilities only, and no Legendre expansion coefficients are given. No resonance parameters, thermal scattering data, or photon data are considered.
5. METHOD OF SOLUTION
6. RESTRICTIONS OR LIMITATIONS
The following limits apply: number of cross-section data points for each reaction type, less than or equal to 4000; number of reaction types on the UKAEA tape, 80/material; number of interpolation regions for ENDF/B data, 10; number of UKAEA reaction types which have angular distribution data, 50, and which have secondary energy distribution data, 50 per material.
7. TYPICAL RUNNING TIME
10 seconds CPU time per nuclide on the IBM 360/91 is typical.
8. COMPUTER HARDWARE REQUIREMENTS
UKE-III was designed for and is operable on the IBM 360/91/75. Approximately 30 K words of directly addressable core storage are needed. Two tape units and two scratch disks are used in addition to the I-O units.
9. COMPUTER SOFTWARE REQUIREMENTS
UKE-III may be compiled and executed on the IBM OS/360, Fortran H-level compiler.
