Swelling of Highly Neutron Irradiated Beryllium and Titanium Beryllide
The swelling of beryllium and titanium beryllide after irradiation at 70–750 °C to neutron fluences of (0.25–8) · 1022 cm−2 (E > 1 MeV) was measured using methods of immersion, dimension, and helium pycnometry.

Ab initio investigation of properties and mobility of helium defects in La2Sn2O7 pyrochlore
The accumulated helium atoms mitigate the physical properties of nuclear waste forms through long-time radionuclide decay and thus cause the safety concern. In this work, first-principles calculations were carried out to investigate the effects of helium
