摘　　要：燃料元件包壳的水侧腐蚀和吸氢是当前进一步提高燃耗的主要限制因素，由于一回路水中加入Ｈ３ＢＯ３和ＬｉＯＨ，使包壳的腐蚀问题变得更为复杂。本文综述了ＬｉＯＨ及ＬｉＯＨＨ３ＢＯ３对锆合金水侧腐蚀的影响，以及研究这种影响机理的现状。Extending fuel burnup is limited mainly by the waterside corrosion and hydriding of fuel cladding.Due to the addition of H3BO3 and LiOH in the primary loop,the corrosion behavior of fuel cladding becomes more complicated.The effect of LiOH or LiOH H3BO3 on the corrosion behavior of fuel cladding,and the research status of the mechanism of LiOH degradation and H3BO3 repair of ZrO2 films have been described .
