This specification applies to composite pellets composed of mixtures of nuclear-grade aluminum oxide and boron carbide that may be ultimately used in a reactor core, for example, in neutron absorber rods. Specimens shall be sampled and tested as appropriate, and shall adhere accordingly to required chemical compositions, physical dimensions, density, boron carbide homogeneity, mechanical properties, visual appearance, end and circumferential chips, cracks, and fissures and other defects.

1.1 This specification applies to pellets composed of mixtures of aluminum oxide and boron carbide that may be ultimately used in a reactor core, for example, in neutron absorber rods.

1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
