Abstract
India is currently operating two BWR built by General Electric Company. The design features of these reactors are similar to the Fukushima's BWR except some better containment features in Indian BWR. This paper discusses the enveloping scenario of station blackout of infinite duration with no operator action and no component failure. The paper describes the details of modelling the TAPS-BWR plant model including SCDAP modelling of reactor core in system code RELAP5 and further thermal hydraulic safety assessment of station blackout scenario. The analysis brought out effectively the response of the plant to this high-pressure severe accident scenario. The time line of the severe accident progression will give details of various stages of accident progression along with hydrogen generation, which will be useful in evolving suitable severe accident management guidelines.
Kurzfassung
In diesem Beitrag werden Rechnungen mit RELAP5/SCDAP zum Notstromfall in den zwei KKW Tarapur vorgestellt. Beide KKW sind Siedewasserreaktoren und wurden von General Electric errichtet. Das Design ähnelt den SWR in Fukushima. Der zeitliche Ablauf des gewählten Szenarios wird im Beitrag vorgestellt.
