Significance and Use | ||||||||||
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 C 752. 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. |

1. 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:
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. 7.1 This test method is applicable to the determination of silver, indium, and cadmium in alloys of approximately 80 % silver, 15 % indium, and 5 % cadmium used in nuclear reactor control rod applications. The titrimetric methods presented , will yield results with a bias of the order of 0.1 %. 16.1 This test method is applicable to the determination of the trace impurities listed in 19.1 in silver-indium-cadmium alloys. |
