The helical steam generator is connected to an HTGR-type nuclear reactor called PeLUIt-40 for production. Steam used generate electricity and hydrogen. A once-through tube bundle was employed because of its ability endure mechanical stress due thermal expansion, high resistance flow-induced vibrations, better performance compared a straight one. To produce the targeted steam, design analysis ne...

Abstract The XPZ code was previously developed for the lattice physics computation in High Temperature Gas-cooled Reactors (HTGRs), which adopted multi-group cross section library converted from existing open-source DRAGON library. In this paper, a new format of named XPZLIB has been implemented code. is designed binary and HDF5 formats, including detailed data contents resonance, transport dep...
