Welcome to the Kraken wiki.

Kraken is a reactor analysis computational framework developed at VTT Technical Research Centre of Finland Ltd.

This wiki will document the developed solvers and their coupling and using instructions.

The framework as a whole is still very much under development and functionalities described in this wiki may substantially change from version to version.

Setting up Kraken

Codes under development

• Ants nodal neutronics code.
• Cerberus multi-physics driver code.
• FINIX fuel behaviour module.
• Kharon porous medium thermal hydraulics code.
• Serpent Monte Carlo particle transport code.
• KrakenTools Python 3 package for pre- and postprocessing purposes.
• SuperFINIX core level fuel behaviour module.
• TRACEWrap wrapper code which enables Cerberus communication with NRC code TRACE.
• TUWrap wrapper code which enables Cerberus communication with fuel behaviour code TRANSURANUS.
