This paper discusses, specifically, the primary containment response of a large pool-type reactor under HCDA conditions. A large-diameter, thin-walled, pool-type reactor may have some inherent safety advantages in terms of energy accommodation during HCDA loads. The purpose of this study was to predict the containment response from the energetic excursion and to determine the impact loading on the reactor deck for a more detailed analysis. The essential features of the primary system which were modelled include the reactor core, radial shield, redan (separating the hot and cold pools), core support structure (CSS), upper internal structure (UIS), the sodium coolant, and the reactor vessel. Three different UIS configurations were studied and the effects of flow paths on the primary containment response were noted. In each case the primary systems were identical except for the upper internal structure (UIS) which was parametrically varied to simulate; (1) annular flow, (2) a horizontal guide plate, and (3) a cylindrical shroud with guide plate.
