Standard Specification for Nuclear-Grade Silver-Indium-Cadmium Alloy
ABSTRACT
This specification covers silver-indium-cadmium alloy for use as a control material in light-water nuclear reactors. The use of this material in applications is excluded where material strength of this alloy is a prime requisite. Also, this material must be protected from the primary water by a corrosion and wear resistant cladding. The identity of each lot by melt number shall be maintained at all stages of manufacture. Parts produced to this specification shall be made from billets by hot working and cold finishing to size. The cold-finished parts shall be produced to the finish condition and dimensions as specified. The surface of the cold-finished part shall be free of oxides, grease, oil, residual lubricants, inclusions, and other extraneous materials. Surface defects such as folds, cracks, seams, slivers, and blisters shall be cause for rejection.
SCOPE
1.1 This specification covers silver-indium-cadmium alloy for use as a control material in light-water nuclear reactors.
1.2 The scope of this specification excludes the use of this material in applications where material strength of this alloy is a prime 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 as standard.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
