Effect of Fast Neutron Irradiation on the Structure of Boron Carbide

Effect of Fast Neutron Irradiation on the Structure of Boron Carbide

The leading LMFBR control rod material, B4C, was examined by SEM, TEM, and X‐ray diffraction after irradiation up to 80 × 1020 captures/cm3 between 500° and 920°C. Bulk swelling was found to be the result of elastic and plastic strains, rather than dilation of the unit cell. Microcracking was observ...

Zusammenfassung:The leading LMFBR control rod material, B4C, was examined by SEM, TEM, and X‐ray diffraction after irradiation up to 80 × 1020 captures/cm3 between 500° and 920°C. Bulk swelling was found to be the result of elastic and plastic strains, rather than dilation of the unit cell. Microcracking was observed and explained in terms of anisotropic swelling.
