OpenMCTallyEditor

A UserObject for creating and managing OpenMC tallies

Description

This user object can be used to change the nuclides, filters, and scores on a given OpenMC tally. This object is primarily used for facilitating depletion coupling of OpenMC to MOOSE, where new tallies need to be registered with controllable parameters to account for changing compositions during depletion.

Example Input Syntax

Below is an example which will create an OpenMC tally with controllable parameters to obtain an absorption rate from only U-238, ignoring the all other nuclides in the problem.

    Description:Whether to multiply the tally by the current material's atom density

Optional Parameters

  • allow_duplicate_execution_on_initialFalseIn the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

    Default:False

    C++ Type:bool

    Controllable:No

    Description:In the case where this UserObject is depended upon by an initial condition, allow it to be executed twice during the initial setup (once before the IC and again after mesh adaptivity (if applicable).

  • execute_onTIMESTEP_ENDThe list of flag(s) indicating when this object should be executed. For a description of each flag, see https://mooseframework.inl.gov/source/interfaces/SetupInterface.html.

    Default:TIMESTEP_END

    C++ Type:ExecFlagEnum
