Fission Product Distribution in ORR Fuel Elements

PDF Version Also Available for Download.

Description

The gamma rays emitted by ORR fuel elements and by the fuel section of shim rods are measured as a function of position along the elements with a very small graphite ionization chamber. Comparison of the fuel burnup calculated from the gamma measurements and by the flux-time method shows good agreement. This means that the gammaray distribution measurements could be a good method of determining the U/sup 235/ consumption in fuel elements. Distributions of the macroscopic absorption cross section and the infinite multiplication factor along fuel elements are computed from the gamma dose rate distribution. The limited usefulness of the ... continued below
