%FTEM Card

This card is used to input fuel temperature parameters.

%FTEM	Variable	Description	Remarks
LINE 1	CFTEM	Uniform distribution of the fuel temperature in Kelvin	Used as guess if %THER card active
	RFTEM	Fuel temperature reference in Kelvin from which the interpolation is done	Dummy if %XTAB card is active
LINE 2	FISGTR(g)	Macroscopic Cross Section changes due to changes of fuel 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
	FSIGA(g)
	FNUF(g)
	FSIGF(g)
	FSIGS(g,1:NG)
LINE 3	POPT	Print option if users want to print this card	Optional

Example:
