Reduced Order Model and PRA: A Multi-Unit Perspective

摘要

In this paper we have presented some consideration about the use of ROMs to perform Dynamic PRA for a multi-unit plant. While the original multi-unit Dynamic PRA analysis has been presented in , here we have focused on the main modeling aspects when ROMs are employed in conjunction with the actual simulation code. We have shown how ROMs can be set to best represent plant dynamics and how the estimation error can be measured. In particular, we have presented analysis focused especially on the convergence and validation of the response of the generated ROMs.
