(Test Method)Standard Test Methods for Chemical and Spectrochemical Analysis of Nuclear-Grade Silver-Indium-Cadmium Alloys
Standard Test Methods for Chemical and Spectrochemical Analysis of Nuclear-Grade Silver-Indium-Cadmium Alloys
SIGNIFICANCE AND USE
3.1 Silver-indium-cadmium alloy is used as a control material in nuclear reactors. In order to be suitable for this purpose, the material must meet the specifications for assay and impurity content. These test methods are designed to show whether or not a given material meets the specifications as given in Specification C752.
3.1.1 An assay is performed to determine whether the material has the chemical composition specified.
3.1.2 The impurity content is determined to ensure that the maximum concentration limit of impurities is not exceeded.
SCOPE
1.1 These test methods cover procedures for the chemical and spectrochemical analysis of nuclear grade silver-indium-cadmium (Ag-In-Cd) alloys to determine compliance with specifications.
1.2 The analytical procedures appear in the following order:
Sections
Silver, Indium, and Cadmium by a Titration Method
7 – 15
Trace Impurities by Carrier-Distillation Spectro-
chemical Method
16 – 22
1.3 The values stated in SI units are to be regarded as the standard.
1.4 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. For specific hazard and precautionary statements, see Section 5 and Practices E50.
