Transient and Safety Analysis Code for TP-1 Sodium Cooled TWR Available to Purchase

As a new concept of reactor, traveling wave reactor (TWR) is under fundamental research. In this paper, we modeled the main parts of primary loop of TP-1 sodium cooled traveling wave reactor, which was designed by TerrraPower Co., and developed a Transient and safety Analysis code for Sodium cooled TWR (TAST) with Fortran program. We first performed a steady analysis based on this code to evaluate the accuracy of this code. The calculated results agreed well with design parameters. After this, this program was used to simulate the loss of flow accident and reactivity insertion accident separately. The transient safety analysis indicated that TWR can work safely under these two accident conditions.
