MIHAMA POWER PLANT ACCIDENT Since the first ever nuclear power plant was established in Russia 57 years ago in 1954, there have unfortunately been some serious accidents. Despite being a relatively cheap and clean energy source, when something goes wrong, the dangers can be enormous.

In 2004 there was a serious accident, killing five and injuring six people, at Kansai Electric Power Corporation (KEPCO)’s Mihama Power No 3 Station in Japan. It occurred just as the reactor was about to undergo routine maintenance and involved the rupture of a pipe carrying pressurised water in the secondary circuit of the power station. When the pipe ruptured it released an enormous jet of steam into the turbine hall, killing and injuring several of those in there. As soon as the fire alarm was activated, an order was announced over the public broadcast system to evacuate the turbine building, an ambulance was called for and the nuclear safety inspector's office, which was assigned to supervise the Mihama Power Station, was also informed. At full power that steam would have normally been at 195ºC and at pressure of about 180psi. A 55 mm wide rupture was found in part of the condensate piping. At the time of the accident, the pipes were carrying approximately 885 tons of water in the form of steam. The thickness of the walls of the piping was 10 mm when the plant began operating in 1976 and the design had specified they should be at least 4.7 mm thick. However, where the pipe ruptured, it was only 0.4 mm at the thinnest spot. The investigation team found that the inner surface of the piping uncovered a shiny scale-shaped pattern indicative of “erosion corrosion”, a phenomenon whereby the pipe walls are eroded by the interaction of corrosion due to mechanical and chemical effect. Subsequently is it was found that, in 27 years of operation, the pipe and never been checked and routine inspections had only been done visually instead of ultrasonically, which is the only way to check accurately. Although between 1998 and 2003 many pipes had been replaced in two other power stations, they had not been replaced at the No 3 plant. The amount of corrosion reflected a major fault, either in the design or in the inspection routine. If regular inspections had been carried out, they would have revealed the weakened state of the pipes. Now seven years on, Kansai Electric has made significant changes. The company immediately undertook to prevent a reoccurrence of the problem and to restore public trust in the company by, for example, enhancing the strength of system, ensuring worker safety and re-examining the management of the pipes for the secondary system. 5 Complete the summary paragraph with words from the box.
