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 6.9.0 - Released 11/3/2023:
- A new numeric connection management system has been added for external junction typed hydraulic components. This new functionality allows assigning numeric integer values to connection locations. When those numerics are changed (or when the user defined functions execute), the connection locations are automatically updated to the location defined by the numeric.
- Added the Included Views node to the comparison dialog for restart cases.
- The ASCII import logic has been updated to convert the values in a UDN prefix for British Models.
- Numeric Integers that are enumerations have been updated to export to the resource map with their integer value, not the enumeration name.
- Importing a resource file with unix substitution does not trim the input line after 80 characters.
- Importing a resource file when the resource model is open no longer alters the names of the numeric variables.
- A new numeric connection management system has been added for external junction typed hydraulic components. This new functionality allows assigning numeric integer values to connection locations. When those numerics are changed (or when the user defined functions execute), the connection locations are automatically updated to the location defined by the numeric.
- General Tables have been updated to support being defined as a Unitless table. This allows using any engineering unit of variable in the table.
- Updated the T-Flag property for Time Dependent Volumes to allow numerics.
- The T-Flag property in Time Dependent Volumes now displays an understandable representation of the selections.
- The B-Flag property and T-Flag properties for Time Dependent Volumes have been removed from the Fluid Conditions dialog and added to the Time Dependent Volume component property view.
- The Additional Junctions Data property tab for hydraulic components is now enabled whenever there’s one or more values to be set inside the table.
- ECC Mixer, Jetmixer, Turbine, and Feedwater Heater components have been updated to include a property that can be used to edit junction connections.
- The Control Input Selection Dialog has been modified to sort Control Systems alphabetically and then numerically off the component numbers.
- Drawn Control Blocks were updated to label each input connection.
- An issue was fixed in which the unitless type for GeneralTable was incorrectly exporting numerics to their converted value.
- An issue was fixed in which the ASCII import with unix substitution was converting values before the models engineering units were determined.
- The sub-system integration behavior for general tables has been updated to resolve the appearance of a false error message.
- The preserve numerics behavior for restart cases was updated to resolve an issue where unitless general tables would not identify numerics referenced in the table data.
