A MONTE CARLO STUDY OF THE RESONANCE ABSORPTION AND ITS TEMPERATURE VARIATION IN A SQUARE URANIUM-GRAPHITE LATTICE

Technical Report ·
OSTI ID:4203398
A program written for the IBM 704 to calculate neutron cross sections for a heavy even-even nucleus in the resonance region is described, and a program for calculating by Monte Carlo the resonance absorption of such an isotope in a particular reactor lattice is given Results are given for the Calder Hall lattice at three different temperatures and for a scaling up and a scaling down of this lattice for two of these temperatures. The results are linked with analytical expressions in the unresolved resonance region and compared with experimental results and other calculations. (auth)
