PARCS Plug-in

Purdue Advanced Reactor Core Simulator for reactor kinetics simulation.   The Purdue Advanced Reactor Core Simulator (PARCS) is a computer code that solves the time-dependent two-group neutron diffusion equation in three-dimensional Cartesian geometry using nodal methods to obtain the transient neutron flux distribution. The code may be used in the analysis of reactivity-initiated accidents in light water reactors where spatial effects may be important. It may be run in the stand-alone mode or coupled to other NRC thermal-hydraulic codes such as RELAP5 and TRACE.  Through coupling with TRACE, the capabilities for RAMONA, NRC's legacy kinetics code are recovered.

Change Log

Version 2.9.2 - Released 4/01/2024:

  • Updated to support PARCS version 3.4.3.
  • The code version selector for the ASCII import dialog was updated to be a drop-down list
  • The Depletion Cycle component was updated to fully support the PARCS version 3.4.3 CYCLE_DEF updates. This includes reading in the data in tabular format. A Depletion Step property was also added to modify the independent variable for the cycle definitions.
  • The HCR_TREAT record on the Core Depletion Component has been updated to support an array of values in PARCS version 3.4.3, as well as the additional value of -1, Pyrex or BP Insert Weighting
  • The Core Geometry component has been updated to make the Rect. Symmetry property an optional property as it is no longer affecting the simulation.
  • The Transient Component has been updated to show the default value for Global and Local Fission from the Parameter Component if they are not active within the Transient Component but must be shown.
  • The Transient Component has been updated to include a new optional attribute group named Biasing Options.
  • The Temp. Convergence value will not be shown on the CONV_TR card if the models version is greater than or equal to 3.3 and will only be shown on the CNV_TH_TR card. if the version is less than 3.3, the Temp. Convergence value will be shown on the CONV_TR card.
  • A fix has been implemented for the caching the incorrect import path for various files being used within a PARCS model.
  • An issue was resolved when importing the Multi-Cycle component LOCATION card without the Assembly ID Control Flag property.
  • An issue was resolved in Model Options that resulted in some External TH properties being disabled in Coupled mode.
