The SPES3 Experimental Facility Design for the IRIS Reactor Simulation

Table 2

SPES3 Test matrix summary and main goals.

Test type	Break	Purpose	Notes
Lower break	SBLOCA: DEG and SPLIT break of DVI	Verify the dynamic coupling between primary system and containment; the maximum containment pressure, the RPV mass and core temperature	All safety systems available except for a single failure on an ADS train
Upper break	SBLOCA: DEG break of EBT to RPV line
ADS break	SBLOCA: DEG break of ADS single train		Maximum PRZ steam space break
FL break	DEG break of FL	Verify the plant response to non-LOCA events	Partial EHRS actuation
SL break	DEG break of SL
Safe Shutdown sequence	Loss of all power	Verify the safe-shutdown sequences	Investigate the primary coolant shrinkage, natural circulation, EHRS HX cool-down capability
