Programme

This is a hands-on training course that covers the use of ORIGEN for depletion and decay analysis, nuclide inventories, decay heat, and radiation emissions and spectra calculations.

Instruction is provided to enable all participants to:

  • Understand what ORIGEN is: ORIGEN’s capabilities for depletion and decay analysis, type and role of nuclear data and nuclear data libraries, capabilities of other modules in the ORIGEN family (ORIGAMI, OBIWAN, OPUS, ARP).
  • Gain confidence in creating, validating, and running input with SCALE’s graphical user interface, Fulcrum.
  • Learn best practices for determining nuclide inventories, decay heat, and radiation emissions and spectra in spent nuclear fuel and activated materials.
  • Gain hands-on experience through interactive tutorials and challenging real-world workshop problems: perform typical calculations with ORIGEN and ORIGAMI; determine nuclide inventories, decay heat, radiation emissions; generate ORIGEN reactor libraries using TRITON; generate and apply ORIGEN activation libraries; post-process, view, and analyze results.

The training will be presented using the latest maintenance release in the SCALE 6.3 series. No prior knowledge of SCALE is required.

Registration

The registration fee is 1500 EUR. This includes lunch and coffee breaks, but does not cover accommodation.

As soon as your registration has been accepted, you will receive the necessary information to proceed with payment ahead of the course, either by credit card or by bank transfer. 

Registrations will be open until places run out. We draw your attention to the fact this course can only host 20 participants, so please do not delay in registering and paying the course fee.

Note aux participants français : l'OCDE/NEA n'est pas un centre de formation. Pour cette raison, les frais d'inscriptions sont dus avant le début de la prestation et il ne sera pas établi de convention de stage.

Practical information

Participants are expected to bring their own laptop (with charger and cable) capable of connecting to Wi-Fi and allowing connections to the internet. They must arrive with the SCALE code installed for use in the classroom. It is strongly recommended that the installation DVDs also be brought (and a way to read them) in case the code needs to be reinstalled on the student's laptop during the class.
