OLD BARNYARD: A CROSS SECTION CODE FOR SCHOOL USE

Abstract

OLD BARNYARD is a digital computer code which calculates few group fast and thermal neutron cross sections and constants. The first of two sequential chains calculates the neutron flux needed to determine the group cross sections. The code uses the moments method to find the fast flux and solves the Wilkins equation numerically for the thermal flux. The code is written in Fortran for a small computer, the IBM 1620, and is intended for use by students and professors in support of classroom assignments.
