The in-Pool Energy Removal System for Emergency Operation (PERSEO) has been developed in the framework of an ENEA research program on innovative safety systems with the purpose to increase the reliability of passive Decay Heat Removal (DHR) systems implementing in-pool Heat Exchanger (e.g. the Isolation Condenser system of the SBWR). The system, conceived to enable the control of the removed power by modifying the thermal exchange conditions directly in the pool, was originally studied within the frame of an ENEA-CEA cooperation.The present configuration was defined and tested at the SIET laboratories in Piacenza (Italy) exploiting the experience and the equipment of the GE-SBWR IC and PCCS experimental campaigns. The thermal-hydraulic system codes RELAP and CATHARE were widely applied for the definition of the PERSEO experimental program. The former was utilized to support the facility design, whereas the pre-test analysis was performed with both codes. Thus the experimental campaign, executed at full scale and full thermal-hydraulic conditions, achieved two important results; besides investigating the behaviour and performance of PERSEO in steady and unsteady conditions, it allowed the qualification of the RELAP and CATHARE models.This paper aims at supplying an exhaustive description of all the experimental and analytical activity performed as well as at summarizing the main results achieved.

Abstract
The in-Pool Energy Removal System for Emergency Operation (PERSEO) has been developed in the framework of an ENEA research program on innovative safety systems with the purpose to increase the reliability of passive Decay Heat Removal (DHR) systems implementing in-pool Heat Exchanger (e.g. the Isolation Condenser system of the SBWR). The system, conceived to enable the control of the removed power by modifying the thermal exchange conditions directly in the pool, was originally studied within the frame of an ENEA-CEA cooperation.The present configuration was defined and tested at the SIET laboratories in Piacenza (Italy) exploiting the experience and the equipment of the GE-SBWR IC and PCCS experimental campaigns. The thermal-hydraulic system codes RELAP and CATHARE were widely applied for the definition of the PERSEO experimental program. The former was utilized to support the facility design, whereas the pre-test analysis was performed with both codes. Thus the experimental campaign, executed at full scale and full thermal-hydraulic conditions, achieved two important results; besides investigating the behaviour and performance of PERSEO in steady and unsteady conditions, it allowed the qualification of the RELAP and CATHARE models.This paper aims at supplying an exhaustive description of all the experimental and analytical activity performed as well as at summarizing the main results achieved.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
