On this page: Publication Information AbstractDownload complete document NUREG/IA-0413 (PDF - 3.07 MB)Publication Information **Manuscript Completed:** March 2012**Date Published:** March 2012 **Prepared by:** S. Gallardo, V. Abella, G. Verdú and A. Querol Universitat Politécnica de Valéncia Camino Vera s/n 46022 Valencia, SPAIN A. Calvo, NRC Project Manager **Prepared as part of:** The Agreement on Research Participation and Technical Exchange Under the Thermal-Hydraulic Code Applications and Maintenance Program (CAMP) **Published by:** Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Washington, DC 20555-0001 Availability Notice Abstract The purpose of this work is to overview the results provided by the simulation of a cold leg Small Break Loss-Of-Coolant Accident (SBLOCA) under the assumption of total failure of high pressure injection system in the Large Scale Test Facility (LSTF) via the thermal-hydraulic code TRACE5. The work is developed in the frame of OECD/NEA ROSA Project Test 3-1 (SB-CL-38 in JAEA). Test 3-1 simulated a PWR high-power natural circulation due to failure of scram during cold leg SBLOCA with a break size equivalent to 0.1% of the cold leg under assumption of total failure of High Injection System. A detailed model of the plant and the chronology of events, following these assumptions, has been developed with TRACE5. A comparison of the simulation of the test with the experimental results is provided throughout several graphs. An acceptable general behaviour is observed in the entire transient. In conclusion, this work represents a good contribution for assessment of the predictability of computer codes such as TRACE5.
