Повний текст джерелаThe aim of this study is to evaluate the risk of stress corrosion cracking (SCC), in the conditions of the nuclear waste storage in deep geological layer, on the carbon steels which are postpone for the construction of the lining and the canisters. References, regarding the SCC susceptibility of buried pipelines, show two types of SCC, trans- and intergranular, which are related to two potential - pH domains. Usually, transgranular SCC is attributed to hydrogen embrittlement mechanism and intergranular SCC to film rupture processes. Slow strain rate tests (SSRT) were performed in order to identify SCC susceptibility domains on samples extracted from prototypes representatives of the canisters. As SSRT tests overestimate the potential SCC susceptibility, a one year duration experiment was carried on to evaluate the materials resistance toward crack initiation under static loads representatives of residual stresses. SCC tests results did not allow us to exclude, as regards to the expected chemical conditions, intergranular SCC risks. Nevertheless, we observed delayed cracking caused by the poor quality of the selected steels which are far from the usual recommendations specified for buried pipelines. Thus, a dedicated experimental program, for this deep geological storage, is set up to assess carbon steel selection compliant with existing specifications

Повний текст джерелаThe present study relates to the problem of the long-term interim storage of nuclear wastes. In France, it is envisaged that high-level radioactive wastes will be confined in a glass matrix, stored in a stainless steel canister, itself placed in a carbon steel overpack. The wastes will then be stored at a depth of ~450 m in a deep geological disposal, drilled in a very stiff (indurated) clay (argillite) formation. A temperature as high as 90°C is expected at the steel surface because of the intense radioactivity. Anodic polarization at applied current density was used to synthetize corrosion product layers likely to be formed in storage conditions. The S235 steel electrodes were covered by a layer of argillite and dipped in carbonated solutions. The synthesis was first achieved at 25°C to determine the parameters controlling the nature of the corrosion products and then at 80°C to be closer to the real conditions. The nature of the obtained compounds proved to be dependent on NaHCO3 concentration, on current density and on polarization time. At 80°C, magnetite Fe3O4 and siderite FeCO3 were the main identified compounds. Carbonate green rust FeII4FeIII2(OH)12CO3.2H2O and chukanovite Fe2(OH)2CO3 were detected locally in some experiments. Iron sulfides, mainly mackinwaite, also formed at the beginning of the experiments with a moderate current density. In the second part of the study, the influence of sulfide species on the steel / model corrosion products layer system was investigated. The modifications of the layers previously formed by anodic polarization induced by sulfide species were more particularly studied. Finally, the last part of our research was focused on the effects of a galvanic coupling that could appear between two areas of the steel coated by different corrosion products. In particular, galvanic couplings involving magnetite Fe3O4, the main conductive compound likely to form under storage conditions, were studied

Повний текст джерелаMetallic infrastructures immersed in natural seawater are exposed to important corrosion phenomena, sometimes characterised as microbiologically influenced corrosion. The presence of alloying elements in low alloy steels could present a corrosion resistance improvement of the structures. In this context, tests are performed with commercial steel grades, from 0,05wt% Cr to 11,5wt% Cr. They consist in “on site” immersion in natural seawater on the one hand, and in laboratory tests with immersion in media enriched with marine sulphide-producing bacteria on the other hand. Gravimetric, microbiological, electrochemical measurements and corrosion product analyses are carried out and show that corrosion phenomenon is composed of several stages. A preliminary step is the reduction of the corrosion kinetics and is correlated with the presence of sessile sulphide-producing bacteria and an important formation of sulphur-containing species. This phase is shorter when the alloying element content of the steel increases. This phase is probably followed by an increase of corrosion, appearing clearly after an 8-month immersion in natural seawater for some of the grade steels. Chromium and molybdenum show at the same time a beneficial influence to generalised corrosion resistance and a toxic effect on sulphide-producing bacteria. This multidisciplinary study reflects the complexity of the interactions between bacteria and steels ; sulphide-producing bacteria seem to be involved in corrosion processes in natural seawater and complementary studies would have to clarify occurring mechanisms

Повний текст джерелаThe aim of the work is to assess the susceptibility to environmental assisted cracking (EAC) of steels used for the deep geological storage of radioactive waste. The storage concept is based on the encapsulation of the waste in a carbon steel containers then placed in micro-tunnels drilled 500 meter deep in Clay. These micro-tunnels are built with a micro-alloyed casing steel. Recently, the storage concept has evolved with the injection of a cementitious bentonite grout between the clay and the casing to balance the potential acidity resulting from the excavation of the micro-tunnels and the gradual saturation of rock with water. Effect of this grout on the risk of corrosion and EAC is also evaluated in the PhD work. In the mild disposal environment considered (pH close to neutrality, low carbonate content), formation of a corrosion product scale composed of siderite and magnetite has been identified. This scale leads to a pseudo-passive state of both steel grades with thus a possible risk of EAC. The risk of EAC was thus first studied and a material selection for the disposal concept was thus first made accordingly. The protective nature of the siderite/magnetite corrosion scale was then studied and reproduced in laboratory using electrochemical techniques. This work allowed for the evaluation of the resistance of each selected steel with respect to general corrosion and EAC. The results did not underlined significant cracking susceptibility of the considered steel grades. Under deposit corrosion seems to be the main form of attack in aerated waste disposal environments but the influence of the presence of low oxygen levels has to be further explored

Повний текст джерелаUnalloyed steels selected by Andra for nuclear waste storage would be mainly affected by general corrosion. The aim of this study is to demonstrate that it is possible to simulate the long term corrosion rate in order to estimate the thickness of the containers expected to maintain the confinement for several centuries. Modeling by the finite element method, based on the resolution of Nernst-Planck equation in free potential conditions has been used to predict the electrochemical behavior of these steels impossible to reach at long time through laboratory experiments. From parametric studies (influence of electrochemical kinetic constants, kinetic constants dealing with chemical reactions, temperature) and in the light of several comparisons between laboratory and numerical experiments, it was possible to determine all the parameters and all the rules to build and use the most completed predictive numerical model.The main result of this study is a long term prediction model. After a first step it was established that dissolved oxygen initially trapped is consumed, whereas the corrosion rate is controlled by the fractional coverage of the surface due to the formation of corrosion products (magnetite, siderite). As a consequence, the decrease of the total porosity can be identified as a key parameter in the reduction of the corrosion rate
