Change Log
Version 1.2.5 - Released 7/6/2010:
- A warning message has been added to alert the user when the RN package default scheme is set to 1.8.6.
- The 1.8.6 sensitivity coefficients conversion logic was updated prevent converting type 7106 as a class-based nuclide coefficient.
- The 1.8.6 conversion logic for control volumes was updated to set a control volume with no pool properties defined as an atmosphere only volume.
- The RN release combination editor has been modified to correctly edit the release class.
- Support for the new CCF model input was provided as follows:
- ASCII read support was added for Melcor 1.8.6/2.1 CCF input.
- A new category was added which allows creation of CCF model components.
- ASCII write logic was added for exporting the new CCF model input.
- Read/Write MED logic was added for saving and loading the CCF model components. - A conversion issue was resolved where the read logic for control functions which had the same name spelling but different capitalization was assigning control connections to the wrong component.
- A read issue was resolved which could result in core component ring/level data to be lost on a MELCOR 1.8.6 import.
- The RN release model (ICRLSE) property's editor was update to allow for selection of values 5 and -5.
- An issue was resolved that prevented the EXEC_DTMAXCF card from being written.
- The Melcor 1.8.6 concrete species C(C) and CA(OH)2 are now converted to the appropriate 2.1 equivalent types C-C and CA-OH-2.
- An issue was resolved in the 1.8.6 Control Volume conversion logic that prevented the time-dependent material mole fractions table from being enabled correctly.
- The Burn component import logic was updated to support importing a default value for the CDIM variable defined as DEF.
- An issue was resolved that prevented Drawn Control Volume from remaining in a visual "Layer" when re-opening a view.
- The COR_QHS card ICOMP attribute editor was updated to display the proper enumerated values.
- Melcor 1.8.6 control volume type names (CVTYPEnn) will now be set on the converted volumes.
- An issue was resolved in the control volume import logic where CV_THR card value ICVACT(Active/inactive switch) was defaulting enumeration DELAYED-ACTIVE to ACTIVE.
- An issue was resolved which prevented reconnecting to custom radionuclide class elements when importing a converted model.
- An issue was resolved where the material type specification editor was reporting an exception when opened.
- The MELCOR ASCII import batch command was modified to include a field to specify the model version.
- The Core component 1.8.6 conversion logic was modified to resolve an issue converting the control function heat source component data.
