Description

To quantitatively study the effect of pressure-tube ballooning and sagging on accident progression in CANDU reactors, the previously developed and benchmarked mechanistic channel deformation models have been integrated into RELAP/SCDAPSIM/Mod3.6 as new SCDAP subroutines. In this paper, this modified SCDAP/RELAP5 code is used to simulate the station blackout accidents for a generic 900MW CANDU plant. The main focus of this paper is on the impact of these new CANDU specific models on the predicted event timings. The sensitivity to decay heat portioning especially the fraction of heat directly deposited to the moderator is also investigated. (author)
