The use of system codes in scaling studies: relevant techniques for qualifying NPP nodalizations for particular scenarios
Rights accessRestricted access - publisher's policy
System codes along with necessary nodalizations are valuable tools for thermal hydraulic safety analysis. Qualifying both codes and nodalizations is an essential step prior to their use in any significant study involving code calculations. Since most existing experimental data come from tests performed on the small scale, any qualification process must therefore address scale considerations. This paper describes the methodology developed at the Technical University of Catalonia in order to contribute to the qualification of Nuclear Power Plant nodalizations by means of scale disquisitions. The techniques that are presented include the so-called.. V-scaled calculation approach as well as the use of
