Remote-area power supply systems system design

Currently, remote I/O systems of several manufacturers are available for operation in zone 1 or Division 1. To a large extent, these systems are based upon the technology of intrinsic safety. The power supply only is designed according to another type of protection, e.g. flameproof enclosure - d A remote I/O suitable for hazardous areas may be an integration of input (I) and output (O) assembly units of automation systems and of Ex i-isolators of classic design. The installation may be made in a hazardous area and supersede the classic field distribution box (terminal box). Standardized fieldbus systems may be used for data transmission from/to the automation system. These remote I/O systems for hazardous areas are characterized as follows ... 

What is mentioned above is obviously expected for the nuclear energy in the twenty-first century. Some concepts about FRs as well as LWRs have already been su ested, and their design studies have also been carried out. It is expected that these concepts will be developed and used to create the above mentioned nuclear energy systems the safety systems to be described more simply, the economical nuclear energy systems to be placed near metropolises, and the power supply systems in remote areas far fi"om transmission networks. These ideas are also applicable to other systems such as reprocessing plants instead of one large plant that can reprocess spent fuel for tens of reactors, the installation of smaller plants is under discussion along with the discussion on advanced fuel cycle concepts.
