This paper describes the implementation of the Bodner–Partom model for the analysis of copper corrosion barrier in canisters containing spent nuclear fuel. The Bonder–Partom constitutive model implemented in CODE_BRIGHT finite element code is compared with experimental results for validation and with the Stealth finite difference code for verification. Deep geological disposal is the most reliable alternative for the spent nuclear fuel storage. This disposal is based on the multiple barriers principle. Different barriers will prevent the release of the radionuclides and one of the barriers is the canister that will contain the spent fuel. The canister will be constructed mainly in cast iron for giving mechanical protection to the spent fuel with a copper shell for protecting the cast iron against corrosion. Due to the high strength of metals, the canister components will keep it inside the elastic region during the hydration of the buffer, so it has not been necessary to implement more accurate constitutive models for the simulation. The canister is considered more as a boundary condition rather than a component to be analysed when the hydration and swelling processes are assessed but in case of relative displacements between the lips of joints intersecting a deposition hole because of an earthquake induced by the increase of vertical load due to the accumulation of ice during a glaciation or any other tectonic effect, not likely in Baltic shield, the stresses in canister could be high enough for reaching plastic conditions and in this case, it is considered necessary to use more accurate constitutive models for the simulation of the canister–buffer system.

本文介绍了Bodner-Partom模型的实现，该模型用于分析包含乏核燃料的碳罐中的铜腐蚀障碍。将以CODE_BRIGHT有限元代码实现的Bonder-Partom本构模型与用于验证的实验结果进行比较，并与用于验证的Stealth有限差分代码进行比较。深度地质处置是乏核燃料储存的最可靠替代方案。这种处置基于多重障碍原则。不同的屏障将阻止放射性核素的释放，屏障之一是将容纳乏燃料的碳罐。碳罐将主要由铸铁制成，以对乏燃料提供机械保护，并带有铜壳，以保护铸铁不受腐蚀。由于金属的高强度，罐组件在缓冲液水合期间将其保持在弹性区域内，因此不必为仿真实现更精确的本构模型。在评估水合作用和溶胀过程时，但由于垂直载荷增加引起的地震，在与沉积孔相交的接头唇缘之间存在相对位移的情况下，该罐更多地被视为边界条件，而不是要分析的组件由于在冰川期或其他任何构造作用期间积聚了冰块（在波罗的海盾构中不太可能），因此罐中的应力可能足够高，可以达到塑性条件，在这种情况下，有必要使用更精确的本构模型罐缓冲系统的仿真。
