Braches Calculation

Postby Marpreri » Fri Nov 08, 2013 1:12 pm


I´m using Serpent 2 to generate cross sections in order to make a coupled code calculation.
First of all, I can´t entry to serpent 2 dsicussion, so I´m going to ask here.

Could you explain me how I can change the range of temperatures, I need one diferent temperature for each branch?

Can I write:
mat UO2 -10.4 ettm 560
92234.06c 0.93967954E-05
92235.60c 0.92807856E-03

I have to keep .06c? or if i change the calculation temperature, I have to change also this number?

Serpent 2 looks for the minimum temperature in the ettm entries and pre-broadens the cross sections to that temperature. Materials at higher temperatures are handled using the on-the-fly treatment. In general, the closer the library temperatures are to the final temperatures, the better.
