An integrated ingress of coolant event (ICE) test facility was constructed to demonstrate that the ITER safety design approach and design parameters for ICEs are adequate. The major objectives of the integrated ICE test facility are: to estimate the performance of an integrated pressure suppression system; to obtain validation data for safety analysis codes; and to clarify the effects of two phase pressure drops at the divertor and condensation in the suppression tank. The integrated ICE test facility simulates the current ITER components with a scaling factor of 1/1600. The TRAC-PF1 code is used to verify the integrated ICE experimental results. From the present study the effectiveness of the ITER pressure suppression system was verified experimentally and analytically, and then it was clarified quantitatively that the prediction accuracy of the TRAC-PF1 code is very high.
