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 2.6.6 - Released 11/27/2018:

  • The cross section ASCII export behavior has been updated to always include cross-sections when the function type is inactive, and cross-sections have been defined.
  • The function type editor in the main cross section component has been updated to display the text "Unspecified" in red when the function type is active but has not been set.
  • An issue with the function type editor has been resolved which would cause an error when changing active function type, and prevent the function change from being undoable.
  • The cross section file editor in the general cross section data has been updated to support undoing and redoing the activation checkbox.
  • A minor job stream issue has been resolved where models could include built-in cross section files in the job stream submission when the built-in cross sections are disabled.
