One of the tasks of the EU-FP7 JASMIN project is devoted to the assessment of the thermal-hydraulic module CESAR of ASTEC-Na V1.1 code on the basis of in-pile experiments (CABRI and SCARABEE) and out-of-pile experiments planned in the KASOLA facility at KIT to address single phase flow phenomena. Pre-test analyses of KASOLA base loop configuration have been performed with the ASTEC-Na code in various operating conditions and the ASTEC-Na results have been benchmarked with other codes (CATHARE, RELAP5-3D and RELAP5-Na). Steady-state at different power levels under both forced and natural circulation conditions have been calculated with these codes. Besides, transient conditions related to unprotected loss of flow (ULOF) and unprotected loss of heat sink (ULOHS) situations at different nominal power levels have been investigated. These pre-test analyses have highlighted the right operation of the KASOLA facility under different convective flow regimes in the primary loop and the safe removal of primary power through the sodium-air heat exchanger. The benchmarking with other codes has confirmed the suitability of the new thermal-hydraulic models implemented in ASTEC-Na and the reliability of the obtained results.

Abstract
One of the tasks of the EU-FP7 JASMIN project is devoted to the assessment of the thermal-hydraulic module CESAR of ASTEC-Na V1.1 code on the basis of in-pile experiments (CABRI and SCARABEE) and out-of-pile experiments planned in the KASOLA facility at KIT to address single phase flow phenomena. Pre-test analyses of KASOLA base loop configuration have been performed with the ASTEC-Na code in various operating conditions and the ASTEC-Na results have been benchmarked with other codes (CATHARE, RELAP5-3D and RELAP5-Na). Steady-state at different power levels under both forced and natural circulation conditions have been calculated with these codes. Besides, transient conditions related to unprotected loss of flow (ULOF) and unprotected loss of heat sink (ULOHS) situations at different nominal power levels have been investigated. These pre-test analyses have highlighted the right operation of the KASOLA facility under different convective flow regimes in the primary loop and the safe removal of primary power through the sodium-air heat exchanger. The benchmarking with other codes has confirmed the suitability of the new thermal-hydraulic models implemented in ASTEC-Na and the reliability of the obtained results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
