Abstract

A FORTRAN code is described which computes high energy events in thermal reactors having cylindrical ruel elements.The HEETR code is based on transmission and escape probabilities.Code calculations are compared with experimental determinations or the ratio or 238 U to 235 U riSSions ror lattices or natural uranium tubes and rod clusters in D 2 0. Good agreement is obtained ror lattices or single rods, but code calculations tend to exceed experimental values ror lattices of tubes and rod clusters.
