Tokai-mura, Ibaraki-ken, Japan 319-1195
Introduction
The Nuclear Science Committee (NSC) of the OECD Nuclear Energy Agency (NEA) organised a Workshop on "Utilization and Reliability of High Power Accelerators." The Workshop was held at Mito, hosted by Japan Atomic Energy Research Institute (JAERI), from the morning of 13 October to the afternoon of 15 October 1998.
Motivation, Scope and Goals
R&D activities and construction plans related to high power proton accelerators (HPPAs) are being considered in various countries to promote basic and applied sciences, including accelerator-driven nuclear energy system (ADS), using neutrons, protons and other secondary particles. Taking into account the fact that proton beams from existing HPPA trip (suddenly stop) very frequently, it is indispensable to understand the effects (e.g. thermal shocks) of such beam trips on different sub-systems, especially fission sub-systems. Additional R&D will be needed to accomplish a highly reliable HPPA and sub-systems resistant to thermal shocks.
The scope of the workshop comprises:
- the experiences and prospects of HPPA utilization,
- reliability of existing HPPAs, especially focused on beam trips and power fluctuations,
- effects of resulting thermal shocks in fission sub-systems,
- required accelerator reliability in various applications,
- R&D of sub-systems resistant to such shocks,
- accelerator types suitable for ADS, interface technology between proton beam and sub- systems,
- control system and safety concept for ADS and problems relevant to utilization (multi- purpose vs. dedicated systems, etc.).
The purpose of the workshop is to exploit more efficient utilization of HPPAs in various fields and to ensure the future possibility of ADS.
Dates and Place of the Workshop
The Workshop started from the morning of 13 October and finished in the afternoon of 15 October.
