Standard Specification for Zirconium Sponge and Other Forms of Virgin Metal for Nuclear Application

SCOPE
1.1 This specification covers virgin zirconium metal commonly designated as sponge because of its porous, sponge-like texture, but it may also take other forms such as chunklets.
1.2 One grade is described which is designated as Reactor Grade R60001, suitable for use in nuclear application. The most important characteristic of the reactor grade is its low nuclear cross section as achieved by removal of hafnium and by careful quality control in manufacturing procedures to prevent contamination with other high cross-section materials.
1.3 Unless a single unit is used, for example corrosion mass gain in mg.dm2, the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. SI values cannot be mixed with inch-pound values.
1.4 The following precautionary caveat pertains only to the test method portions of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
