## Description

- description: Boron carbide (B4C) pellets have been commonly used as neutron absorber
    materials in fast reactor system. In this study, highly microstructure-controlled
    B4C ceramics with carbon nanotube (CNT) and tubal pores were fabricated, and the
    B4C/CNT composites were irradiated with a 30-MeV alpha beam. After irradiation,
    the helium gas release behavior of the alpha-implanted samples was evaluated by
    measuring the release of helium gas. The alpha-implanted samples with tubal pores
    showed the peak which would attribute to the helium gas release clearly from around
    250℃ in TG-MS, whereas alpha-implanted dense sample without porosity did not show
    the peak clearly. It was confirmed that helium gas was released more rapidly from
    the B4C/CNT composites with tubal pores. The results of TG-MS and TEM suggested
    that helium gas can be released effectively from inside the B4C/CNT composites
    even with the same porosity of 5-10% as that of B4C used as neutron absorber materials
    in fast reactors by introducing tubal pores by highly microstructure control.
