A Technique for Gamma Radiographic Inspection of Parallel-Plate Fuel Assemblies

Source

Using a 0.005-in. diameter tungsten wire, a line radiation source of tungsten-185 was prepared by neutron activation. Parallel wires mounted in a holder which fits into the coolant channel were used to locate the core alloy edge, necking, and defects in the core for two adjacent fuel plates in a multiplate assembly.

From the radiation energy viewpoint, thulium-170 was a more suitable radiation source. Thulium is not available, however, as wire, and a development program for the production of uniform diameter thulium wire would be necessary.
