Paper abstract bibtex In this paper different failure modes of the primary circuit pressure boundary of a planned HTR-Module reactor for process heat generation under accident conditions with loss of all heat sinks are assessed probabilistically. It is shown why failure probabilities cannot be expected to represent absolute values but nevertheles, as relative values they permit an effective comparison of components and failure modes. Failure probabilities are calculated under the condition that the postulated accident has actually occurred. They are compared for various cross sections and different failure modes. The failure of the crack-free base material of the forgings as well as the Leak-Before-Break behaviour of the welds is considered. The conditional failure probabilities are to be multiplied with the cumulative frequency, still to be determined, of all event sequences leading to the accident in question to give its contribution to the total failure frequency. This contribution is low.
