At the Kyoto University Research Reactor Institute (KURRI), a new project for research on the accelerator-driven subcritical reactor (ADS) was started in 2002. For this project, a new ring-type accelerator based on the up-to-date FFAG (fixed field ...

A spallation target system is a key component in the development of an accelerator-driven system (ADS). It is known that a 15-25 MW spallation target is required for a practical 1 000 MWth ADS. The design of a 20 MW spallation target is very ...

The Japan Atomic Energy Research Institute (JAERI) is conducting the research and development (R&D) on the accelerator-driven subcritical system (ADS) for the effective transmutation of minor actinides (MAs). The ADS proposed by JAERI is an 800 ...

In this work a new approach to the realisation of an accelerator-coupled hybrid system (ACS) is proposed. A significant improvement of the feedback effect due to the particularities of the neutron production in a spallation target is expected. In ...

In the field of waste management incorporating a transmutation option, accelerator-driven systems (ADS) represent an important alternative to conventional reactors due to their higher safety level when minor actinides (such as neptunium and ...

Successful development of a reliable and normal hands-on maintainable high-power linac requires minimisation of beam losses along the accelerator. The high sensitivity of the high-power linac focusing channel to random perturbation encourages ...

The Spallation Neutron Source accelerator system will provide a 1-GeV, 1.44-MW proton beam to a liquid mercury target for neutron production. The accelerator complex consists of an H– injector capable of producing a 38-mA peak current, a 1-GeV ...

In order to support ADS-related technologies, the thermal-hydraulic ADS lead-bismuth loop (TALL) was designed and constructed at KTH to investigate the heat transfer performance of different heat exchangers, and the thermal-hydraulic characteristics ...

Lead-bismuth eutectic (LBE) corrosion has been considered as an important design factor to limit the temperature and velocity of the accelerator-driven transmutation system. For the corrosion study, KAERI finished the set-up of the LBE static ...

The MYRRHA accelerator-driven system (ADS) is being developed in Mol, Belgium incorporating a windowless spallation target, as this is the only option within the constraints of the envisaged neutron source performance. In this paper the research ...

The TRADE (TRIGA accelerator-driven experiment) experiment, which is to be performed in the TRIGA reactor of the ENEA/Casaccia centre, involves the coupling of a 140 MeV, 0.3 mA beam that is produced by a cyclotron to a target hosted in the central ...

Temperature transients induced by beam interruptions of different durations in MOX-fuelled and lead-bismuth cooled experimental ADS are investigated as a WPPT benchmark computational problem. The final report of the second phase of calculations will ...

In this paper we discuss recent work to further improve our superconducting (SC) ADS driver linac design. Our design assumes use of the 6.7-MeV LEDA RFQ as an injector to the SC driver linac. We have examined the feasibility of accelerating a 20-mA ...

Within the Fifth Framework Programme of the European Union (EU), the PDS-XADS project is focused on Preliminary Design Studies of an Experimental Accelerator-driven Reactor System (ADS). Three basic designs are being studied in detail – two ADS ...

Burn-up for the reference core of MYRRHA over a single cycle of 90 days was estimated with MCNPX and SPECTRUM (an MCNPX postprocessor developed at SCK•CEN). Over this cycle, the source multiplication factor ks dropped from 0.952 to 0.941 (Drs = 1 ...
