INTEGRAL TESTING OF THE AP600 PASSIVE EMERGENCY CORE COOLING SYSTEMS

In support of the development of AP600, Westinghouse is conducting two integral systems tests to examine the performance of the passive safe ty systems. A full-height, full-pressure test is being performed to si mulate a small loss-of-coolant, steam generator tube rupture and large steam line break events. A one-quarter scale, low-pressure test is be ing performed to simulate transients with emphasis on the transition t o the natural circulation post-accident, long-term cooling mode and to demonstrate the long-term cooling capability. Each of the tests will provide detailed experimental results for verification of the accident analysis computer codes.
