PERSEO Project: Experimental Facility Set-Up and RELAP5 Code Calculations

The PERSEO project (in-Pool Energy Removal System for Emergency Operation) is part of a research activity on cooling systems, suitable to remove the decay heat from the primary side of a LWR by means of pool immersed heat exchangers. Two examples of such systems are the GE-SBWR IC and the AP-600 PRHR. The PERSEO project is aimed at investigating the possibility of moving the high pressure primary side triggering valve, present in the above said systems, to the atmospheric pressure pool side, in order to increase the system reliability by reducing the presence of active devices on the reactor primary circuit.
