Mechanical testing of zirconium alloys has many uses: to confirm that the material meets the specification, to evaluate new alloys or modifications to old ones, to elucidate mechanisms of strengthening or embrittlement, and to assess the effects of reactor operation. The mechanical response of any material depends on several different parameters such as:
- Specimen geometry,
- Alloy composition and microstructure,
- Loading conditions such as stress state and strain rate,
- Environment such as temperature, irradiation and ambient chemistry.
Residence in a nuclear reactor presents a severe test for materials. Before evaluating the mechanical properties, knowledge is required on the conditions of normal reactor service with its operational variations, the challenge when spent fuel is stored, and the consequences of accidents. Various mechanical tests are done to simulate the conditions faced by fuel cladding and structural components in the reactor. In applying the results from mechanical testing of zirconium alloys to reactor performance, it is crucial to have a good knowledge of the situation being addressed and how the different critical testing parameters affect the material response so the results are useful to predict performance accurately and satisfy regulatory requirements. The objective of this course is to provide this knowledge.
This course involves watching webinars. Complementary reading is optional to even deepen your knowledge. The course material including the online content can be accessed at times convenient. The PowerPoint-presentations are available for download on almost all lectures. You will find them just before the lecture starts.
If you need a printed certificate, please don’t hesitate to contact us and we will send it to you via regular mail. You may reach us at firstname.lastname@example.org.
Please note that these PowerPoint-presentations are the actual file from the seminar that has been recorded. Therefore, there may occur spelling errors and/or less perfect pictures or slides. As the presentations are the expert’s own material we have not edited them before making these lectures available online.
