R&D of validity evaluation system for seismic simulation of nuclear power plant

Suzuki, Yoshio  ; Miyamura, Hiroko 

Our goal is to evaluate the validity of results obtained from seismic simulation of entire nuclear power plant, and then to estimate real phenomena. In this study, we have established a trial system to evaluate the validity by automatically abstracting a characteristic spatial profile of physical values in consideration of uncertainty caused by discretization, as one of methods to reveal factors of various uncertainties included in the simulation. By applying the system to a seismic simulation, we have confirmed that various characteristic spatial profiles of stress with error estimation are automatically classified and abstracted from the simulation result.
