Ideal scaling up of BETHSY experimental results
- Univ. of Ljubljana (Slovenia)
The transient scenario of ISP-27 (International System Problem) was applied in the analysis for real NPP (Nuclear Power Plant). The scenario involves a diameter 5.1 cm (2 inches) cold leg break without available HPSI (High Pressure Safety Injection) and hypothetical operator procedure for secondary system depressurization. The objective was to evaluate the ideal scaling up of BETHSY (Boucle d`Etudes Thermohydraulique Systeme) facility proposed accident management procedure for real NPP and to compare the physical phenomena known from experimental background with the phenomena predicted by RELAP5 simulations of real plant transient. Also, special attention was concentrated on those parts of RELAP5 model where possible multidimensional phenomena may occur.
