Beam window breakage is one of the accidents under consideration for the operation of an accelerator-driven subcritical system (ADS). After the beam window breaks, the target material [lead-bismuth eutectic (LBE)] flows into the beam duct in liquid ...

In an accelerator-driven system (ADS), a target system is incorporated. The main purpose of the target system is to produce excess neutrons, which brings the subcritical reactor core in an ADS to critical condition. Critical condition allows for ...

This paper is concerned with the transmutation of TRUs in DUPIC (direct use of spent PWR fuel in CANDU) spent fuel in the HYPER system, which is an LBE-cooled ADS. The DUPIC concept is a synergistic combination of PWR and CANDU, in which PWR spent ...

Comparative safety analyses and investigations were performed for a small-scale ADS with conventional MOX fuel and an 800 MWth power class ADT with advanced fertile-free fuels, both cooled by Pb/Bi. The analyses covered perturbations of the source ...
