high reliability non-line-of-sight nuclear power plant RPW wireless communication system
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 ...

Condensation Dry-well cooler Element test Heat removal Natural circulation Non-condensable gas Primary containment vessel Severe accident
日立 GE 安藤 浩二 Kouji ANDOU Non-Member The new dry-well cooler (DWC) for a severe accident has been developed to avoid release of radioactive materials to environment caused by primary containment vessel failure. The DWC can be operated using natural driving force to remove decay heat. The element tests using copper tube bundle with 3 rows and 5 levels were conducted under existing nuclear power plant conditions to estimate heat removal ratio with non-condensable gas (N2) and to confirm occurrence of natu...
