assessment of a hypothetical repository at a realsite.The main objective of the project is to determine how site specific data should beassimilated into the performance assessment process and to evaluate how uncertaintiesinherent in site characterization will influence performance assessment results.Otherimportant elements of SITE-94 are the development of a practical and defensiblemethodology for defining,constructing and analyzing scenarios,the development ofapproaches for treatment of uncertainties,evaluation of canister integrity,and thedevelopment and application of an appropriate Quality Assurance plan forPerformance Assessments.  \nJohan Andersson  \nProject Manager  \nList of contents  \nAbstract  \n1 Introduction1  \n224  \n2 Pourbaix diagram  \n2.1

for dissolved copper species have also been calculated.Fivedifferent total concentrations(10⁻³,10⁴,10⁶,10⁸and 10⁻⁹molal)for dissolved copperhave been used in the calculations.  \nCopper is a noble metal,but it corrodes with hydrogen evolution at low pH,both at aconcentration level of 10⁶m at T≥125℃,and at a concentration of 10⁸m fromT≥50℃.The oxides(Cu₂O(cr)and CuO(cr))are stable at all temperatures andconcentration levels≥10⁻⁸m,with the exception of 10⁻⁸m at T≥100℃ where theoxides are not stable.The copper(II)hydroxide,Cu(OH)₂(cr),is not thermodynamicallystable in the interval investigated.Cu predominates at T>80℃ at all concentrationslevels.CuOH(aq)appears in the Pourbaix diagrams only at the lowest concentrations,and in the predominance diagram for dissolved species at 125 and 150℃.Cu(OH)₂predominates at all temperatures and concentrations investigated.The completehydrolysis series of copper(I)and (II)have not been included in earlier publishedPourbaix diagrams,and these species are covered for the first time in this work.  \nAt acidic pH,increasing temperature decreases the immunity area,and therefore,itincreases the corrosion of copper.At alkaline pH-values corrosion also increases withthe temperature due to the decrease of both the passivity and immunity areas.  \nThe calculated diagrams are used as a base for the discussion of the corrosion behaviourof the copper canisters in the Swedish radioactive waste management program.  \n## 1Introduction\n\nAccording to the concept KBS-3 developed by SKB¹project,spent nuclear fuel will bedisposed in a system of several safety barriers.One of these is a duplex metal canisterconsisting of an outer copper vessel and an inner steel vessel.Copper has been chosen asthe reference material for the ongoing development work mainly due to its excellentcorrosion behaviour.  \nThe expected life time of the 5.0 cm thick copper vessel
