ABSTRACT:
This is a high quality zirconium or hafnium sponge, a fuel element cladding liner having material of the quality of this sponge and a process utilizing this quality sponge to fabricate liner material for lined fuel element cladding. The sponge contains 250-about 350 ppm of oxygen impurity, 50-300 ppm of iron impurity, and a total of 500-1,000 ppm of impurity. This material is much purer than conventional sponge and approaches the quality of crystal bar.
