The present tests have been conducted in taking note of double rupture disc's behavior to evaluate characteristics of the disc opening and pressure wave propagation way when an initial spike pressure is generated in the no cover-gas type steam generator of the secondary coolant system under the sodium-water reaction. Another objective is to get the data useful for verification of analytical codes. In the experiments, the initial spike pressure is simulated by an underwater explosion of a slow burning explosive which is set in the steam generator model of the water loop equipment (PEPT) as well as Phase (I) tests. The following burst characteristics are identified by the high-speed photographing of the jetting water and the rupture discs with synchronization ; In the case of the source pressure of about 30 kg/cmg at peak with 20 ms in width at the central position in axial direction of the steam generator, the jetting water moves out at about 50 m/s in the air plenum between the double rupture discs after the first disc bursting. Though the air is compressed according to the jetting water, the second rupture disc is ruptured by the water hammer of the splash which passes firster than the main flow part at 2.5 kg/cmg as the air does not reach the set burst pressure of the disc(5 kg/cmg). The tests have been also executed under the parameter such as the location of the rupture disc or disc types and each characteristics were experimentally grasped. These data can be used for the analytical code verification.
