High reliability is essential to wireless communication system in nuclear power plants. Since there are many obstacles made of metals in nuclear power plants, most of transceivers are located in the non-line-of-sight environment. The non-line-of-sight environment makes highly-reliable communication difficult. To solve this issue, we have proposed the rotating polarization wave (RPW) communication for instrument control. In this report, the effectiveness of the RPW is evaluated in the actual factory and the ...

Application of wireless technology to nuclear power plants

If the wireless communication is feasible in the concrete structure of power plants, it is effective for us to reduce the construction cost, improve the placement of equipment and change facilities easily. In buildings of such a power plant, the reinforced concrete (RC) walls might be more than one meter in thickness, with high rebar density. Therefore, radio wave transmission over this kind of concrete walls was studied to discuss feasibility. Aperture parts of walls, such as doors, whose thickness is ...
