(Specification)Standard Specification for Nuclear-Grade Gadolinium Oxide (Gd2O3) Powder
Standard Specification for Nuclear-Grade Gadolinium Oxide (Gd<sub>2</sub>O<sub>3</sub>) Powder
ABSTRACT
This specification provides chemical and physical requirements for nuclear-grade gadolinium oxide powder intended for subsequent processing and use in nuclear fuel applications. Chemical requirements of the specification include loss-on-ignition, gadolinium oxide concentration, and impurity content limits. The buyer shall specify the particle size, density, shape factor, and crystal structure. Gadolinium oxide powder shall be packaged in sealed containers.
SCOPE
1.1 This specification provides the chemical and physical requirements for nuclear-grade gadolinium oxide powder intended for subsequent processing and use in nuclear fuel applications, for example, as an addition to uranium dioxide.
1.2 This specification does not include requirements for health and safety. Observance of this specification does not relieve the user of the obligation to be aware of and comply with all federal, state, and local regulations pertaining to possessing, shipping, processing, or using this material.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
