Validation Analysis for Improved Application of the Riera Method to Aircraft Engine Impact Analysis on Spent Nuclear Fuel Transport Casks

사용후핵연료 운반용기에 대한 항공기 엔진 충돌해석 시 개선된 Riera 방법 적용방안의 유효성 확인

The study proposes an improved application of the the Riera method, which based on trial and error method, to aircraft engine impact analysis on spent nuclear fuel transport casks. The improved application was applied to the case where an aircraft engine simulation model collides with a rigid wall, and finite element explicit dynamic analysis was performed. In addition, the results of the improved application method were compared with those of the full model and the existing Riera method. The comparison results confirmed that the proposed improvement application is an efficient and reliable method that matches well with the full model.
