| The three steels investigated are resistant to pitting corrosion in all brines, and their general corrosion rates imply corrosion allowances acceptable for thick-walled containers. | |
| The observations suggest that uniform corrosion of containers prevails under open field conditions. | |
| Multiple lines of evidence can be helpful in building confidence in the long-term behavior (corrosion and dissolution) of the canister and waste form. | |
77 Citations | The possibility of stress corrosion cannot be dismissed, but, because the process requires a certain minimum stress level before it can occur, it should be possible to avoid the problem by giving the containers a stress relief heat treatment. |
47 Citations | This indicates the plausibility of SRB growth during the construction and operational phases of the repository and their survival at least temporarily after the disposal closure if water is available, which may cause fast corrosion of the steel containers under disposal conditions. |
01 Jul 2017 | This strategy works fine for short-lived containers. |
201 Citations | The scanning vibrating electrode technique also shows an effective healing ability of containers to cure the corrosion defects. |
| Waste storage and collection sites of the area should be monitored periodically and waste should be disposed of in a scientific manner in sanitary landfills. | |
19 Citations | Such corrosion data from archaeological samples are useful in analogue studies of high-level radioactive waste disposal as evidence of long-term stability of a waste container. |
20 Citations | Stochastic models of pitting corrosion have been explored and found to be potentially useful in predicting damage of high-level radioactive-waste containers. |
35 Citations | Limited rates of mass transport through compacted clay are also important in determining the corrosion behaviour of both the cannon and the containers. |
35 Citations | In response, the corrosion behaviour of the containers will also change with time as the repository environment evolve. |
52 Citations | Environmental conditions within the emplacement drifts, such as composition of solutions contacting the waste packages, can also affect localized corrosion susceptibility. |
| In a repository this would increase the possibility of in situ activity, which might be detrimental for the longevity of waste containers. | |
| Results of independent constant-medium tests, stagnant tests, and flow tests on simulated nuclear waste glasses show excellent agreement in the determination of the maximum corrosion rates. | |
| The corrosion rates determined imply corrosion allowances that are technically acceptable for thick-walled containers. |

What are the common causes of corrosion in copper sludge receiving tanks?5 answersCommon causes of corrosion in copper sludge receiving tanks include factors such as the formation of insoluble compounds due to high pH solutions, sedimentation leading to oxygen concentration differential cells, and the presence of thin oxide films on tube surfaces. The high pH solutions used to neutralize acidic wastes in the tanks can cause the formation of insoluble compounds, leading to sludge accumulation. Additionally, sedimentation containing compounds like CaCO3 or PO43/Mo042 supplied by corrosion inhibitors can accelerate corrosion by forming oxygen concentration differential cells. Moreover, the presence of scattered thin oxide films on tube surfaces, originating from oxidization by humid air, can increase corrosion potential and accelerate pitting corrosion in copper tubes used in the tanks.
How to detect heavy metalls in waste water?5 answersHeavy metals in waste water can be detected using various methods. One approach is the use of electrochemical sensors with a chronoamperometric protocol, which allows for sensitive and selective detection of heavy metal ions. Another method is the application of microfluidic detection systems, which offer advantages such as portability, high sample throughput, and reduced reagent consumption. Analytical chemistry also plays a crucial role in the quantification of heavy metals, requiring the development of more efficient methods and techniques. Additionally, methods using elemental atomic absorption, optical emission, and mass-spectral ecoanalytical monitoring have been employed for the detection of heavy metals in waste water. These methods contribute to the monitoring and control of heavy metal contamination in waste water, ensuring the protection of natural systems and human health.

What are the effects of corrosion on concrete sewers?2 answersCorrosion has significant effects on concrete sewers. The corrosion of concrete sewer pipes is primarily caused by continuous contact with corrosive materials such as wastewater and sulfuric acid. Corrosion leads to a reduction in the pipe wall thickness and severe structural deterioration. The mass loss of concrete exposed to sewage flushing increases with flow velocity and flushing duration. The corrosion layer formed on the surface of concrete in sewers is porous and easily washed away, providing little protection to the concrete. Corroded sewer pipes show pathologies in both the internal and external faces, with the presence of products detrimental to their durability. The corrosion of concrete sewers can result in the failure of the sewer system and the need for costly remediation and replacement.
Did storage time can affect corrosion on PCB ENIG?5 answersStorage time can affect corrosion on PCB ENIG. The corrosion mechanism of PCB-ENIG involves microporous corrosion and electrochemical migration (ECM) caused by galvanic effects. The protective properties of the corrosion products on PCB-ENIG can be damaged easily under certain atmospheric environments. However, the abstracts provided do not directly address the specific impact of storage time on corrosion.
