Helium retention and its effect on boron carbide irradiated in a fast reactor

Conference ·
OSTI ID:7188698
The principal parameters affecting performance of boron carbide as a neutron absorber material are its helium retention and swelling during irradiation. Experiments in the EBR-II reactor at temperatures of 540-1000/sup 0/C and to burnups of 80 x 10/sup 20/ captures/cm/sup 3/ of boron carbide have been performed. Data indicate pellet swelling and integrity relate directly with helium retention.
