Mihama-3 is an 826 MW Mitsubishi-built pressurized water reactor (PWR) plant situated in Mihama, Japan, 320 km west of Tokyo. The carbon steel pipe carried the high-temperature steam at high pressure and the pipe was not inspected since the inception of the plant in 1976. In April 2003, Nihon Arm, a maintenance subconttac-tor informed Kansai Electric Power Company, the plant owner, that there could be a problem. Then the power company scheduled an ultrasonic inspection for August 2004. Four days before the scheduled inspection, superheated steam blew the 60-cm wide hole in the pipe. The steam that escaped was not in contact with the nuclear reactor and hence no nuclear contamination has been reported. 

As mentioned earlier, the first LWR in Japan was the JAERIJPDR which started operating in 1963. The reactor is of the plate construction type and the material was SA302B modified. The first commercial nuclear power plant was JAPCO s Tokai 1 which went into operation in 1966. The RPV was the Calder HaU-type made of JIS SB46 modified (Coltuf 26 equivalent) plate steel. After that, JAPCO constructed the Tsuruga 1 BWR plant in 1965. The Tokyo Electric Power Company (TEPCO) and Kansai Electric Power Company (KEPCO) also decided to construct the Fukushima 1...
