Core damage frequency

TL;DR: Several detailed approaches that are applicable to multi-unit Level 1 PSA for sites with up to six or more reactor units are provided.

TL;DR: In this paper, the ASCE 43-05 performance-goal-based approach was used to establish the safe shutdown earthquake (SSE) site specific design response spectrum (SSRS) for future nuclear power plants.

TL;DR: The DQFM method has the following features compared with the minimal cut set (MCS) method used in the well known Seismic Safety Margins Research Program (SSMRP): while the MCS method gives the upper bound approximation for occurrence probability of an union of MCSs, the DQ FM method gives more exact results than the upper Bound approximation.

TL;DR: In this article, the authors proposed a method to provide time and condition-dependent risks by integrating a conventional PSA model with condition monitoring and prognostics techniques, which can take a role of annunciator to show the variation of core damage frequency (CDF) depending on operational conditions.
