摘      要：The corrosion behaviour of Alloy 690 under four different zinc addition scenarios was investigated in circulating water containing 2 ppm Li and 1000 ppm B at 330 degrees C. The corrosion rates, release rates, and oxide thicknesses were quantified using gravimetric analyses and oxide compositions. With earlier zinc addition, the corrosion and release rates were accordingly lower and the oxide films were also thinner. This study elaborates on how the radiation source term is suppressed by the zinc addition and the behavior of zinc incorporation into spinel oxides.
