%MTEM Card

This card is used to input moderator or coolant temperature parameters.

%MTEM Variable Description Remarks
LINE 1 CMTEM Uniform distribution of the moderator temperature in Kelvin Used as guess if %THER card active
LINE 2 RMTEM Moderator temperature reference in Kelvin from which the interpolation is done Dummy if %XTAB card active
LINE 3 MISGTR(g) Macroscopic Cross Section changes due to changes of moderator temperature in Kelvin Repeat LINE 2 NG times. And again repeat this input segment NMAT times. This line is not necessary if %XTAB card present
  MSIGA(g)    
  MNUF(g)    
  MSIGF(g)    
  MSIGS(g,1:NG)    
LINE 4 POPT Print option if users want to print this card Optional
