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 2.9.3 - Released 8/14/2025:
- The PARCS plug-in has been updated to support PARCS version 3.4.5
- The card UNIF_FDBK on the TRAN component has been added.
- The FA_POWPIT property 'powfa' has been renamed 'pow_assm_mw'.
- A new FDBK card THERM_POW has been implemented.
- A new TH card PRESSURE has been implemented.
- The HCR_BPRA record has been deprecated from DEPL components.
- cr_hist_treat has been renamed to user_hcr_treat
- cr_hist_weight has been renamed to user_hcr_weight
- Two new Nodal Kernel types, NEMSPN and MGFD, have been added to the PARAM Component.
- A new card PIN_SOLVER has been added the PARAM Component.
- The ability to set an eigenvalue lower limit for search options in the CNTL component has been added.
- Support has been added for the following multi-cycle cards: CORE_MAP, FUEL_POOL, BUNDLE_FMT, BUNDLE_ID.
- Support for options DOPL, DENC, and TCOO have been added to depletion cycles.
- An issue was resolved that caused exceptions when opening a property editing dialog for a property that uses the Core geometry when the core component is not enabled.
- An issue was resolved that caused the Multi-Cycle Bank Definitions dialog to not support resizing the columns to a readable width.
