Gamma spectrum and decay heat

Dear all,

I have the composition of spent fuel (16x16 FA), and I would like to calculate the gamma spectrum and decay heat for different cooling times.
I will be happy for some guidance on how to do so.

Thank you very much!

Dear Reuven,

Thank you for posting on the forum.

FISPACT-II is primarily an inventory code, so if you have the spent fuel inventory you can input this using the FUEL keyword

Various options can be set, and cooling times specified, to generate outputs. This is typically done with TIME and ATOMS. See the keyword registry for more details

The gamma spectrum, gamma heat and various other outputs are standard with the ATOMS keyword. The discretization of the gamma spectrum can be controlled using (from version 3-20).

If you have more basic questions, there will be a FISPACT-II training course at the OECD-NEA in Paris June 13-15

Best regards,
