Early pressurized water reactors were originally designed to operate using stainless steel as cladding material but during their lifetime this material was replaced by zirconium-based alloys. However after the Fukushima Daiichi accident the problems related to the zirconium-based alloys due to the hydrogen production and explosion under severe accident brought the importance to assess different materials. In this sense initiatives as ATF Accident Tolerant Fuel program are considering different material as fuel cladding and one candidate is iron-based alloy. In order to assess the fuel performance of fuel rods manufactured using iron-based alloy as cladding material it was necessary to select a specific stainless steel type 348 and modify properly conventional fuel performance codes developed in the last decades. Then 348 stainless steel mechanical and physics properties were introduced in the TRANSURANUS code. The aim of this paper is to present the obtained results concerning the verification of the modified TRANSURANUS code version .
