Problems with fuel: Iran is worried about margins Bushehr reactor

Iran's nuclear program threatens a serious setback: According to press reports have to be removed more than 160 fuel assemblies from the reactor in Bushehr. Experts suspect problems with the new computer worm Stuxnet - and do not exclude a complete failure of the project. Hamburg - According to the head of Iran's Atomic Energy Agency it is "the most extraordinary power station in the world." Striking about the Bushehr reactor is so far above all his decades-long history.


The construction began in 1974 with the help of Siemens engineers. Again and again it came after interruptions, repeated the construction site in the war on Iraq was even bombed. Late last year, then even the infected computer worm Stuxnet reactor. Despite all, Bushehr in February should finally go online.

This obviously is not. Iran informed the International Atomic Energy Agency, according to a report in the New York Times on Wednesday about 163 fuel assemblies that would be from the core of the plant removed. Iran had to remove the whole reactor core, the German Press Agency reported, citing diplomatic sources in Vienna.

The cause of the new breakdown There are only guesses. According to "New York Times, experts think it is just possible that Stuxnet provides again for problems. Although Iran had granted a attack by computer virus, it can supposedly successfully removed from the plant in Bushehr. Russia, with which Iran is ready for the plant, had recently called for further investigation of Stuxnet and warned of a nuclear accident.

Warning of a second case, according to agency reports from Chernobyl has affected the beginning of February Stuxnet control computer and could also disrupt these programs. Therefore have passed at least the possibility that technicians would get when booting the Bushehr reactor in case of failure no error messages.

It could thus lead to a meltdown in Chernobyl. U.S. scientist David Albright repeated in the New York Times, the warnings that Bushehr would be possible in a disaster like 1986 in Ukraine. "With this type of reactor can have an accident like Chernobyl," said the president of the private Institute for Science and International Security.

According to the nuclear engineer David A. Lochbaum the removal of the fuel rods could also indicate a minor technical problem as to the complete failure of the project. "It could be simple and embarrassing, but also mean that the game is over." The latest IAEA report had mentioned the removal of the fuel only in passing.

His focus was on new evidence that Iran's nuclear program is also for military purposes. Thus are the Authority has information suggesting experiments with components of nuclear weapons. The report also indicated, however, that the enrichment of uranium in Iran was suspended for 18 months, giving the bottlenecks in the supply of the raw material.
