A lead-bismuth eutectic (LBE) spallation target design concept has been developed for the subcritical multiplier (SCM) design of the accelerator-driven test facility (ADTF). The design is based on a coaxial geometrical configuration, which has been carefully analyzed and designed to achieve an optimum performance. The target design description, the results from the parametric studies, and the d...

This work is focused on the expansion of Laboratory Reactor Physics and Thermal-Hydraulics (LRT) PSI multi-physics high-resolution core solver nTF/CTF to full cycle analysis for VVERs. The development code modifications depletion calculation scheme presented in detail. 1st X2 benchmark simulated by novel solver. All necessary approximations modeling options optimize computational cost are discu...
