The results of an international code comparison on decay heat are presented and discussed. Participants from more than ten laboratories calculated, using the same input data, decay heat for thirteen cooling times between 1 and 1013 sec. Two irradiation cases were proposed: fission pulse and 3 107 seconds of irradiation of 235U fuel. The results are analysed and compared. This inter-comparison shows that, if the same input data ate used, almost all of the participating codes give very similar results for the decay heat and consequently also for the fission product contribution.
