CRUD in PWR/VVER Coolant (Volume II)

Basic course for Plant Chemists and Fuel Engineers | taught by A.N.T. International

Course description

Welcome!

The purpose of this course is to describe the tools and their application to adequately control the coolant crud in order to improve the fuel and out-core radiation performance. There is an associated course which describes solubility, transportation, deposition and release of crud that helps to better understand the crud behavior under PWR/VVER/CANDU operating conditions. The information given in this and the associated course:

  • Can support the plant chemists to establish their coolant chemistry strategy to achieve the plant specific goals.
  • Is valuable for fuel vendors and plant fuel engineers to understand the influence of coolant chemistry on fuel performance.

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 for practicing engineers and managers. 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.
