In this article, we study a Large-Break Loss of Coolant Accident (LBLOCA) where a guillotine break of one of the main coolant pipes occurs near the reactor pressure vessel (RPV). This initiates a rarefaction wave which propagates inside the RPV. The

A procedure to generate artificial acceleration time histories compatible with predefined target response spectrum is presented. The procedure is demonstrated with three examples. It was found out that the generated artificial histories yield high qu
