Zirconium Alloy Manufacturing

Course for managers and engineers | taught by A.N.T. International

Course description


The purpose of this course is to provide insight how the manufacturing of Zirconium alloy fuel assembly components impact the following:

  • Pellet Cladding Interaction (PCI) Pellet Cladding Mechanical Interaction (PCMI) corrosion and hydriding properties that, in turn, are dependent upon:
    1. Chemical composition
    2. Crystallographic texture and cladding microstructure.
    3. Clad strength/ductility/fracture toughness
  • Re-opening of the pellet-cladding gap, lift-off, which is partly related to the fuel clad creep properties.
  • Excessive dimensional changes (resulting in e.g. excessive Fuel Assembly (FA) bowing) of fuel components that are a function of creep (including oxide induced and residual stress relaxation creep), irradiation growth, and hydrogen pickup in the components.
  • Loss of Coolant Accident (LOCA) performance that is related to hydrogen pickup both during the base irradiation, before the LOCA event, as well as during the high temperature LOCA oxidation.

This course involves watching webinars. A 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 support@antinternational.com.

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.
