This publication intends to summarize a larger work and aims to establish a semi-automatic procedure to translate input decks from TRAC-BF1 to TRACE code. This work was developed at Universitat Politècnica de València (UPV). The main reason for this work is the importance to keep the models updated and adapted to be used on new codes. As a result, it is possible to take advantage of these codes, which are more powerful because of the new techniques used in their development and the increase of computer resources. As a working example, the Peach Bottom II (PB) model is presented. This model was chosen because it is one of the most used plant models to validate new codes or calculation models. Moreover, data is easily available due to the NEA/OECD BWR Peach Bottom Turbine Trip (PBTT) benchmark. This methodology presented hereafter, could be used to translate other TRAC-BF1 models to keep them updated and therefore useful for other applications.
