Traces of explosives detected on Swedish contractor

Two welders working as contractors at the Oskarshamn nuclear power plant in Sweden are being questioned by police following the discovery of traces of explosives on one of the men's bag. The traces of explosives were found during routine entrance controls at the plant. EOn of Germany, the plant's owner, said that the bag did not actually contain any "visible illicit substances", but as traces of explosives were found on the bag the police will examine it further. Part of the plant was sealed off while extensive searches were made. Media reports say that the explosive material was identified by the police as being triacetone triperoxide (TAPT), an extremely unstable material that can be made using household chemicals. The plant's managing director, Lars Thuring, said, "We can establish that our safety routines are working." He added, "Our joint assessment is that the reactor safety was never threatened. We are however taking all necessary measures to verify this, of course." The men were working on one of the plant's three reactors which had been shut down for routine maintenance. The other two units have remained in operation.
