TRACE model of Almaraz Nuclear Power Plant

In the framework of several projects sponsored by the Spanish Nuclear Regulatory Com- mission (CSN) and the electric energy industry of Spain (UNESA), one of the most important objectives is the maintenance and translation of the Spanish NPP models between different codes, such as RELAP5/MOD3, TRAC-M and TRACE. In this context, the DSE-UPM group with the collaboration of Iberdrola Ingenieria and Almaraz-Trillo AIE, have carried out the translation from the RELAP5 model of Almaraz NPP, performed by Iberdrola Ingenieria, to TRAC-M and TRACE. This paper shows the results of different transient simulations. Though, we are in the first stage of validation, it is observed both a good behavior of the model and a good agreement with the plant data. (author)
