To model a non-irradiated period, you could either directly use a decay step, skipping the neutron transport calculation, or explicitly perform a burnup calculation with zero power. However, if you aim to obtain some detector output from that step, you should set a burnup step with very low power, e.g., 1E-6.

Thank you Ana,
I want to calculate decay heat during the decay time.
My goal is to calculate maximum decay heat during "summer outage" for single fuel assembly. And how should I set the decay heat calculation ( I did not find that in manual/wiki)?
Thank you

You can achieve that by calculating decay steps with dep decstep restarting from a burnup calculation at the correct burnup.

The (instantaneous) decay heat is one of the parameters printed out in the ‘_dep.m’ file for each of the depleted materials, MAT_[NAME]_H, or total, TOT_H, for each of the depletion history steps.
