Abstract

The necessity of developing highly sensitive radiographic procedures for the routine inspection of zirconium, hafnium, and uranium alloy nuclear core components and fuel elements is reviewed. Problems encountered in the development of these procedures and some methods used at Bettis Plant to overcome them, such as shape correction forms and two-film techniques, are discussed. The utility of different types of radiographic equipment is discussed in terms of the requirements for the different attributes under inspection.

Exposure data are given for zirconium, hafnium, and uranium alloys in the range of 150 to 1000 kv. Conversion factors relating these alloys to equivalent thicknesses of steel are also given.
