The NEACRP sample model for the PARCS plug-in has been updated to work with newer PARCS stand alone executables.
An issue was resolved in the Control Rod Group Search feature that prevented the Core Depletion -> PMAXS Files -> "Copy" option from being deactivated automatically. This issue caused PMAX files to be incorrectly duplicated and retained after the CRGS run completed.
The "Include Duplicate Rod Sets" option was added to the PARCS job step when executing a Control Rod Group Search. This option determines whether the control rod group search will include calculations with duplicate rod sets (e.g. {1,2,3} and {2,3,1}).
An application definition for the PARCS K-effective extraction tool will be automatically generated when launching SNAP.
An issue was resolved where the Core Geometry hexagonal symmetry angle was not being displayed in the property view.

Version 2.2.1 - Released 3/29/2013:

The PARCS top-down core display beans were modified to resolve an issue that caused the display beans to shrink to an unuseable size. Additionally the validation of planar level cross-section input in the Core component was modified to prevent reporting errors for valid input.
An issue was resolved that prevented PARCS models from being used in an Engineering Template model.
The PARCS plug-in has been modified to include a job step, and executable jar file for building a K-Effective report after a parametric PARCS job step.
The "Keep Results" property was added to the PARCS job step when using the Control Rod Group Search feature. This property allows the user to limit the amount of disk space used by the search by retaining the "Summary Only" (default) or to increase the spaced used to diagnose runtime issues. The "Summary and Inputs" option adds the PARCS input files to those retained after execution. The "All Files" retains the summary files, the PARCS input files, as well as the files output from every PARCS calculation performed by the search.
The plots and summary created by the PARCS control rod group search feature were updated to display the predicted and upper bound values as "worth" rather than "k-eff".
The "predicted worth" wad added to the final plot created by the PARCS control rod group search.
The PARCS plug-in should support defining the duration either as an array of Days, or an array of Burnup fields, and convert between the two values using the optional heavy metal mass property.
The core geometry dialog has been updated to allow selecting the assembly type numbers defined inside the core when the core contains assembly types.
The editing dialogs for the control rod bank locations have the X and Y axis swapped when compared to the ASCII I/O.

Version 2.2.0 - Released 1/8/2013:

Support has been added for a rod-search case. This case enables a rod-search calculation when a stand-alone PARCS model is submitted to PARCS.

Support has been added for the CR_WORTH card of model options.
An field has been added to model options which disables the control rod bank initial position in the model.
The ASCII export logic of the core component was updated to support assembly types with two or more digits for the type name.
The core component was modified to resolved an issue where duplicate control rod banks could be added if CUSTOM_CR fields exist.
The assembly type label for assembly types in the geometry package now support a default value which is not included in the input file.
The PMAX file location can now be specified in two ways: with a simple relative or absolute file path (identical to the previous method) or with a protocol-prefixed URI. When the path specifies a protocol, it indicates a URI used to locate the file during stream execution. This URI may use any custom file accessors available to streams, such as the local file accessor, the Calculation Server file accessor, etc.. When a job stream is processing a PARCS step, it will attempt to locate any files using a prefixed URI and substitute the absolute path to the PMAX file.

Version 2.1.2 - Released 9/5/2012:

An issue has been resolved in the CORE package where after ASCII import, CORE assembly type references to PMAX files in the depletion package were lost. This only affects models that use the ASSY_TYPE data in the CORE component.
The dialog used to select cross-sections (PMAX Files) for the assembly types in the CORE package has been updated to resolve an issue which prevented the selection from being recognized.
The PARCS execution wrapper was updated to resolve an issue that would write an error to the log file if a file in the working directory did not have a file extension.

Version 2.1.1 - Released 6/18/2012:

Support has been added for sets of depletion cases which can be appended to the end of an input file. Each Depletion Case object in the model represents a set of depletion data. The Depletion Case can be selected in the Model nodes of a Job Stream; this results in the full model being exported with the depletion data appended to the bottom of the file.
The table based GUI custom dialogs have been updated to ensure that pressing the OK button while the table editor is still active sets the current value before closing the dialog.
The PATHS component has been updated to support the two methods of defining channel type supported by stand-alone PARCS. The plug-in has been modified to support defining multiple PATHS components within a model. Only one PATHS component can be selected for inclusion in the ASCII export. Selecting one PATHS component automatically de-selects all other PATHS components.
The PARCS model has been updated to include a field which indicates that the model is either a stand-alone PARCS model, or a model that is coupled with TRACE. This flag enables the PATHS components and the depletion cases when set to Stand Alone.

Version 2.1.0 - Released 1/17/2012:

Support has been provided for PATHS (A Steady State Two-Phase Thermal Hydraulic Solver for PARCS Depletion) integration into the PARCS plug-in. This includes:
- A separate PARCS component with ASCII view and other standard component features (diff, notes, etc)
- Read/write routines for PATHs ASCII data.
- Editors for easily configuring channel layout information (for both hex and cartesian core configurations)
- Core dimensioning logic for ensuring appropriate channel configuration.
The Transient component was updated to resolve an error when first setting the scram option to use the table data.
The ASCII import logic for the transient component was updated to allow floating point representation of the scram input control option integer.
The Cross Sections inside the Main cross section component now have a boolean flag indicating that a given cross section should appear in the generated input model explicitly. This allows for references to cross-sections defined through PMAX files.
When importing a PARCS model, a cross section will be created for each PMAX file reference encountered when the depletion option is used.
The logic that controls importing the cross-section references inside a kinetics cross-section, and DELCR components have been updated to be more robust in the way inputs are parsed.
A warning message is now written out when the number of PMAX files is different from the number of cross-sections defined.
