Core level SMR simulations with the Kraken framework

Price: $49

Westinghouse Electric Company recognizes the importance of supporting students pursuing a career in reactor physics. For this reason, Westinghouse will be sponsoring the first 100 student workshop registrants by covering their fees. Contact registrar@ans.org for a discount code before registering. Limited space available in each workshop. Once these seats are filled, you will be put on a waitlist. You must request a discount code before registering. No refunds will be made if you do not contact us before registering.

Organized by Ville Valtavirta, VTT Technical Research Centre of Finland

Kraken is a computational reactor analysis framework developed at VTT for both safety analyses and general research and educational purposes. With the neutronics side building heavily on the in-house Monte Carlo code Serpent, the framework couples novel Finnish solvers for core physics but also couples to state-of-the-art third party solvers. The Python based multi-physics driver Cerberus and the Python package of pre- and post-processing methods KrakenTools aim to simplify core analysis tasks.

This workshop is designed to give introductory training to new and upcoming. To participate in the hands-on portion of this workshop, participants must bring their own laptops with Kraken installed. Kraken will be available through RSICC ( https://rsicc.ornl.gov/ ) and OECD/NEA ( https://www.oecd-nea.org/dbcps/ ) in the near future. An update will be sent once the license can be requested. Participants who are not able to bring their laptop or to obtain the Kraken software in time may still attend the workshop. The material (including inputs for the examples) will be available to license holders in the Kraken-wiki after the workshop.

Agenda:

• Welcome + short introduction to Kraken

• Pre- and post-processing capabilities for Serpent users

• Cerberus - the very simple Python API for Kraken solvers

• Running Serpent via Cerberus - powerful new capabilities

• Reactor analysis with Kraken

  • Introduction to the analyzed SMR design
  • Static simulations
  • Depletion / fuel cycle simulations
  • Time dependent / transient simulations
