2. User-Need: NRO-2011-007 HABIT Code Update and Evaluation
RES COR – Casper Sun (RES/DSA/RPB)
NRO TL – Syed Haider (NRO/DSRA/SBCV)
On-going actions include:
Phase 1: Re-hosting HABIT to Windows 7
- Lockheed Martin (30 W. Gude Drive, Rockville)
- HABIT V1.2 available and TRM in progress
Phase 2: Implementing ACRS recommendations
- Add DEGADIS and SLAB to HABIT code.

3. NUREG/CR-6210 (1996) Abstract
Mentioned HABIT (Computer Codes for Evaluation of Control Room Habitability) is an integrated FORTRAN modules that are used for determining control room (CR) habitability as risk of CR personnel in the event of an accidental release of toxic chemicals or radioactive materials
Discussed the theoretical basis and physical assumptions made by each of the modules in HABIT and gives detailed information about the data entry windows. Three sample runs are given for each of the modules. A brief section of programming notes is included, including input and output files for the sample runs.

4. What’s New in the HABIT v1.2
FORTRAN Modules recompiled using latest 64-bit Intel Visual FORTRAN compiler for compatibility with Windows 7 (64-bit)
Computation code is functionally the same as old FORTRAN modules
New Graphical User Interface (GUI) developed using Microsoft .NET technology
Consistent module interface design (tabs)
Tighter integration amongst modules and interface
Deployable and Runnable on Windows 7 Environment
Section 508 Compliance (muted use of color, JAWS accessibility)
New GUI and Section 508 compliance
Build-in User Manual and user friendly
NRC/TRM certification – in progress

5. Examples screens from HABIT v1.2 GUI

8. HABIT v1.2: Working with Designs
Designs can be created from scratch or imported from HABIT v1.1 Design Packages
New GUI and Section 508 compliance
Build-in User Manual and user friendly
NRC/TRM certification – in progress
New Design From Scratch
Imported Design

9. HABIT v1.2: Working with Designs
Selecting Modules included in the Design
Modules are selected from the Main Window
Main Window displays relationships amongst modules
Main Window displays whether a module is included in the design and whether its been run
Each included module has its own tab
New GUI and Section 508 compliance
Build-in User Manual and user friendly
NRC/TRM certification – in progress

10. HABIT v1.2: TOOLTIPS New GUI and Section 508 compliance
Entering Module Variables
Tooltips provide a convenient way to see the expected range for fields and provide validations prevent entering bad data
Valid Range Tooltip
Validation Error
New GUI and Section 508 compliance
Build-in User Manual and user friendly
NRC/TRM certification – in progress
Required Field Warning
Range Validation Warning

11. HABIT v1.2: Working with Designs
Saving Designs
Designs can be saved through the Design Menu
Saving a design saves the input for all modules within the design (no need to save input for individual modules)
User is prompted to save design upon exiting system
Previously saved design is automatically loaded the next time HABIT v1.2 is opened
New GUI and Section 508 compliance
Build-in User Manual and user friendly
NRC/TRM certification – in progress

12. HABIT v1.2: Working with Designs
Running Modules
Entered variables are inputted into respective FORTRAN code and generated output is stored in the Design Package’s respective directory
Designs are automatically saved when running a module
FORTRAN logging is displayed on the Output Log tab
If a dependency exists between modules (i.e EXTRAN, CHEM), system alerts user.

Add ICRP 60/103 dose coefficients
Add chemicals
Preform HABIT V&V
Add HABIT V1.2 User Manual
Apply TRM

16. Future Enhancements
Use REAL*8 in FORTRAN codes to increase the internal precision of computation from current 7 to 15 digits
Improve visualization of FORTRAN output files in GUI and can be easily importable into Excel©
Improve FPFP_2 Node Graphs
Provide ability to create and modify Nuclide Databases (dose coefficients) directly in GUI
Renew NUREG/CR-6210.
