After the discovery of explosives on the premises of Swedish nuclear power plant Ringhals south of Gothenburg on Wednesday afternoon, authorities quickly raised the threat level at all Swedish nuclear facilities.<\/span><\/p>\n \u201cThey have all raised the threat level as a precaution,\u201d said Maria Str\u00e5hle at the Swedish Radiation Safety Authority (Str\u00e5ls\u00e4kerhetsmyndigheten) to news agency TT.<\/span><\/p>\n The explosive device was found on a large truck that had been on the industrial estate belonging to the plant and was returning into the reactor area, which is more heavily guarded.<\/span><\/p>\n \u201cUnder the first step onto the truck there is a fire extinguisher and that is where the explosive had been placed,\u201d said G\u00f6sta Larsen of the Ringhals plant to TT.<\/span><\/p>\n He said that police suspect that a civilian has prepared the explosive and that it was the size of a \u201csmall fist\u201d.<\/span><\/p>\n The device was not primed and was not large enough to do damage to a reactor, according to Larsen. However, he confirmed that the threat levels had been raised as a result of the find and said that any discovery of explosives on the plant\u2019s premises was \u201cworrying\u201d.<\/span><\/p>\n According to the county police, the device was in the shape of \u201cplastic explosive\u201d and the truck where it was discovered never leaves the plant\u2019s immediate environs.<\/span><\/p>\n \u201cThe truck was entering the guarded area when the device was found by the plant\u2019s own sniffer dogs,\u201d said police spokesman Tommy Nyman.<\/span><\/p>\n The entire premises were searched with sniffer dogs over night but no other discoveries have been found and police so far have no suspects.<\/span><\/p>\n However, a preliminary investigation is under way and the incident has been classified as a suspected sabotage attempt.<\/span><\/p>\n Police will question truck drivers and officers are currently trying to find out where and when the suspected explosive could have been placed on the vehicle.<\/span><\/p>\n \u201cWe will speak to everyone we think could have information about the incident,\u201d Nyman said to TT.<\/span><\/p>\n The device was sent off to the National Laboratory of Forensic Science (Statens kriminaltekniska laboratorium \u2013 SKL) in Link\u00f6ping for testing soon after the discovery and scientists have since confirmed that it was an explosive found on the plant premises.<\/span><\/p>\n
