【摘要】 采用⁶⁰Co γ-辐射源、人工模拟花岗岩地下水和高温高压实验装置,在模拟深处置条件下（处置深度=1000m,t=190℃,p=20 MPa,pH=7.2）,实验研究了花岗岩地下水辐射分解产物对深处置高放废物金属容器材料的氧化侵蚀强度。由实验得出,与无辐射情况相比较,花岗岩地下水吸收140?Gy γ辐照后,水辐射分解产物对不同金属容器材料的氧化侵蚀强度分别增大:铜材——1.5倍,铝材——2.8倍,熟铁——4.3倍,不锈钢——0.7倍。我国在选用高放废物包装容器金属材料、设计容器型式、规格和设计深地质处置库时,必须充分重视地下水辐射分解效应对各工程屏障产生的破坏作用。更多还原

【Abstract】 An experimental study in oxidation corrosion of radiolysis products from irradiated graniticgroundwater on metal material of high-level waste container in the simulated condition of deep ge-ological disposal （t=190℃, p=20MPa, pH=7. 2） is done by means of ⁶⁰Co gamma irradia-tion source, artificial simulated granitic groundwater, high temperature and high pressure experi-mental installation. Contrasting with that in the condition of no irradiation, oxidation corrosionintensity of groundwater radiolysis products on various metal material increases: copper——1. 5times aluminium——2. 8 times, iron——4. 3 times stainless stell——0.7 time. Damage ofgroundwater radiolysis products to various engineering barriers of radwaste disposal repositoryshould be pay attention to when our country selects metal material of high-level waste container,designes container style and deep geological disposal repository.更多还原
