21 NOVEMBER 2012 Swiss nuclear reactor shuts down due to defect ![]() Switzerland's oldest nuclear power plant Beznau is seen in 2011 near Doettingen, northern Switzerland. A reactor at the Swiss nuclear plant shuts down automatically due to a defect, the operator said, stressing that the procedure had been completely safe. AFP - A reactor at a Swiss nuclear plant shuts down automatically Wednesday due to a defect, the operator said, stressing that the procedure had been completely safe. "Block 2 of the Beznau nuclear power plant shut down automatically," operator Axpo said in a statement. "This was triggered by a defect in the non-nuclear part of the power plant. All systems functioned perfectly during the rapid shut-down," it added. Axpo spokeswoman Daniela Biedermann told AFP that the reactor had not yet returned to the grid and that it could only be recommissioned once the defect had been located and fixed. "When the power plant was shut down, steam escaped from the non-nuclear part of the plant," the statement said, adding however that "the safety of the power plant was guaranteed at all times". Switzerland reacted swiftly to the nuclear disaster in Fukushima last year, with parliament deciding to phase out nuclear energy. source:

22 NOVEMBER 2012 Swiss nuclear reactor back up after closure over defect AFP - A reactor at a Swiss nuclear plant that automatically shut down due to a defect was brought back online Thursday evening, the operator said. "After an interruption of around 24 hours, Block 2 of the Beznau nuclear power plant will start producing electricity again tonight," operator Axpo said in a statement. It explained that "a defective safety switch in the non-nuclear part of the plant" had caused the automatic shut-down late Wednesday. The erroneous triggering of the switch had halted the flow of water into the steam generator, which had caused the reactor to shut down, it explained. "The fault was rectified by activating an identical reserve switch," it said, stressing that an inspection showed that all the components affected by the defect were now functioning well. "The Swiss Federal Nuclear Safety Inspectorate (ENSI) approved the restart of Block 2," Axpo said. Switzerland reacted swiftly to the nuclear disaster in Fukushima last year, with parliament deciding to phase out nuclear energy. Under current plans the country's five reactors will be put out of action by 2034. source:
