RELAP5-MOD3 Plug-in

This version of the RELAP5 plug-in is designed to support RELAP5-MOD3.3. This plug-in is available to CAMP members under the CAMP SNAP User's Group (CAMP-SUG) agreement. CAMP members interested in using this plug-in must first complete and send a signed copy of the CAMP-SUG agreement to sug-support@islinc.com.

Some of the features included in this version include:

  • Context sensitive ASCII views.
  • Job Stream Submission.
  • Model Notebook generation in OpenOffice and Microsoft Word.
  • Attribute level tracking of ownership and reviewer data.
  • Graphical Editing of Restart Cases.
  • Preservation of Variable References in Restart Cases.
  • ASCII comparison of components and models.

The RELAP5/MOD3.3 code has been developed for best-estimate transient simulation of light water reactor coolant systems during postulated accidents. The code models the coupled behavior of the reactor coolant system and the core for loss-of-coolant accidents and operational transients such as anticipated transient without scram, loss of offsite power, loss of feedwater, and loss of flow. A generic modeling approach is used that permits simulating a variety of thermal hydraulic systems. Control system and secondary system components are included to permit modeling of plant controls, turbines, condensers, and secondary feedwater systems.

Change Log

Version 6.7.2 - Released 3/22/2023:

  • An issue was fixed where the count property for multi-logical trips was not restart editable.
  • An error was corrected when using python bindings to interact with hydro systems.
  • An error was corrected which prevented sub-system integration from integrating when hydraulic systems were defined.
