1、Designation: C752 13 (Reapproved 2016)C752 18Standard Specification forNuclear-Grade Silver-Indium-Cadmium Alloy1This standard is issued under the fixed designation C752; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of

2、last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers silver-indium-cadmium alloy for use as a control material in light-water nuclear reactors.1.

3、2 The scope of this specification excludes the use of this material in applications where material strength of this alloy is aprime requisite. Also, this material must be protected from the primary water by a corrosion and wear resistant cladding.1.3 The values stated in SI units are to be regarded

4、as standard. No other units of measurement are included in this standard.1.4 This international standard was developed in accordance with internationally recognized principles on standardizationestablished in the Decision on Principles for the Development of International Standards, Guides and Recom
