The energy and climate challenge can be summarized with the four statements: we live in a world where the demand for electricity is increasing, where the use of fossil fuels is threatening the environment, where the use of fossil fuels is not sustainable, and thus we need innovative technological solutions to meet the “decarbonization challenge”. Innovative nuclear power should include...

MYRRHA (Multi-purpose hYbrid Research Reactor for High-tech Applications) is a multipurpose research facility being developed since 1998 at SCK•CEN, based on the Accelerator Driven System (ADS) concept where a proton accelerator, a spallation target and a lead-bismuth cooled subcritical reactor are coupled. MYRRHA will demonstrate the ADS full concept by coupling these three components at a...

ADS has been evolving as ADANES (Accelerator Driven Advanced Nuclear Energy System) after intensive R&D last 5 years in CAS (Chinese Academy of Science). ADANES consist of the recycle fuel burner and the used fuel recycle. ADANES burner is optimized as nuclear waste transmutation, fissile material breeding and energy production in situ from traditional ADS. The fast core/blanket is designed to...

Accelerator Driven Systems have evoked considerable interest in the nuclear community the world over because of their capability to incinerate the minor actinides (MA) and LLFP (long-lived fission products) radiotoxic waste and utilization of Thorium as an alternative nuclear fuel. In the Indian context, due to our vast thorium resources, ADS is particularly important as one of the potential...

Partitioning and transmutation (P&T) technology of long lived radioactive nuclides such as minor actinides (MAs) will be a promising technology to reduce the burden of the geological disposal of the high-level radioactive waste (HLW). The Japan Atomic Energy Agency (JAEA) has been continuously performing research and development (R&D) on the P&T technology. The R&D on the P&T technology in...

Scaling from the ORNL SNS 6% duty factor with 1.4 MW of beam on target to CW operation by appropriate upgrades of components, the traditionally considered Accelerator-Driven System (ADS) goal of 10 MW at 1 GeV is easily surpassed. However, studies have pointed out that even a few hundred trips of an accelerator lasting a few seconds could lead to unacceptable thermal stresses as each trip...

The state of the art of accelerator physics and technologies allows to cope with the challenge of a compact cyclotron driver for an ADS demonstrator aiming at providing a proton beam power in the 5 to 10 MWatt range. The Single Stage Cyclotron Driver (S2CDTM) design studies developped by the AIMA DEVELOPMENT (AD) company show that this concept could bring industrial attractive solutions in...

The presentation will focus on the potential and the main critical issues for high power proton linacs to drive a subcritical reactor. As an introduction the main beam requirements for an Accelerator Driven System (ADS) will be reminded: to safely guide and accelerate a continuous wave (CW) MW class beam with a high level of performance, and thus with an extreme level of reliability. Then, the...

The scientific and technological challenges relative to the integration, in a nuclear power facility, of the three main components of an ADS (an accelerator delivering a high-energy particle beam, a heavy metal spallation target acting as a neutron source when bombarded by ions and a subcritical multiplying medium possibly comprising significant amounts of MA and/or LLFP) are numerous. Their...

The joint international MEGAPIE initiative – MegaWatt Pilot Experiment - aimed for the demonstration of designing, licensing, operating, dismantling, exploring and disposing a liquid metal spallation target at a beam power level of 1 MW. The initiative started in 1999 and resulted in the operation of the MEGAPIE target in the Swiss Intense Neutron Source (SINQ) in 2006. Thereafter, the target...

To reduce the burden of the geological disposal of high-level waste (HLW), the Japan Atomic Energy Agency (JAEA) has investigated an accelerator-driven system (ADS) to transmute minor actinide (MA) included in HLW. Since the ADS is a hybrid system of an accelerator and a subcritical core, there are various inherent issues in the research and development of the ADS. As one of the critical...

A neutron spallation source for an Accelerator Driven System, commonly known as an ADS Target, must be able to function reliably and safely for the ADS concept to take hold as a viable option in the commercial sector. Targets operating at Megawatt level already exist but have, on the whole, been optimised with physics in mind. The "ideal" ADS target should, in addition to physics...
