Assessment of the Turbine Trip Transient in Santa Maria de Garona Nuclear Power Plant with TRACE version 4.16

摘要

This report presents the results of the assessment of the TRAC/RELAP Advanced Computational Engine (TRACE) code, version 4.16, using the model of the Santa Maria de Garona Nuclear Power Plant to simulate the transient that occurred on June 23, 1992, when a false high-level signal in the moisture separator caused an automatic trip of the main turbine. The steady state was adjusted by connecting submodels of portions of the system previously tuned to the desired conditions. The results show a good agreement with data for all the compared variables. The results of the calculations were in reasonable agreement with plant measurements. The simulations were run on a Pentium IV 3.4 megahertz under Windows XP with 32 bits executable. This report was prepared by the Computer Science and Intelligent Systems Group belonging to the Applied Mathematics and Computer Science Department of the University of Cantabria, which collaborates in the area of simulation with the company Nuclenor S.A., owner of the nuclear power station Santa Maria de Garona. The Asociacion Espanola de la Industria Electrica (Electric Industry Association of Spain) and Nuclenor S.A. sponsored this work.
