RELAP to TRACE conversion - NCG Conversion

[WDunsford]

RELAP5/MOD3 manometer problem. 20 cell pipe that is bent in the middle to form a u-tube. 10 cells are oriented downward and 10 cells are oriented upward. Volume initial conditions t-flag is set to 4, which means that pressure, temperature, and static quality in equilibrium conditions are input. Using this 
input option with static quality > 0.0 and < 1.0, saturated noncondensables will result. When static quality is input as 0.0, then dry noncondensable gas is assumed. The initial conditions used in the manometer problem have static quality set to 0.0 in cells 1 - 5 and cells 16 to 20. the static quality in cells 6 to 15 is set to 1.0e-9. The inlet and outlet of the pipe are connected to TDVs via SJC. The initial conditions are of the TDVs are set to t-flag 4 and the static quality is set to 0.0. The noncondensable gas is set to nitrogen on card 110. 
When converting the RELAP5 model to TRACE, the following is noted:

1. The nitrogen is not converted. Namelist variable IGAS should equal 5 (nitrogen), but is set to 1 (air). 
2. The TDVs are converted to BREAK components, but pain (noncondensable pressure) is set to zero, but the BREAK Table has the correct input for pa (noncondensable pressure). I believe that pain should be set to the same value in the table.
3. The total pressure and temperatures are converted correctly in the pipe and break components.
4. The void fraction in the pipe component for cell 1 - 5 and cells 16 - 20 are converted correctly, but the void fraction in cells 6 - 15 (where water should be) is set to 1.0, so there is no water in the pipe. 
5. There is an initial pipe liquid and vapor velocity set in the R5 model. That velocity is converted over correctly. 
6. The total pressure, temperatures and noncondensable pressure are converted correctly in the pipe component. 
   I have attached the RELAP5/MOD3 SNAP med file for your use.
