The on-again, off-again saga of the San Onofre Nuclear Generating Station Unit 1 reactor?s journey for burial at Barnwell, South Carolina, is on once again. The U.S. Department of Transportation (DOT) cleared the way this week to ship the primary radioactive decommissioning unit?s corpse around the tip of South America and back north to the waste facility. DOT granted a hazardous materials exemption after being convinced SONGS owner Southern California Edison had, among other things, the means to handle the reactor if it tipped overboard in heavy seas. ?They have a $50 million policy to salvage anything lost,? Joe Delcambre, DOT spokesperson, said. DOT also required the reactor to be accompanied by two tugs throughout the journey. The 770-ton vessel is too heavy to go through the Panama Canal, and sending it on the more treacherous path around the Cape concerned transportation officials. But the DOT?s green light still has a few shades of yellow in it. According to Edison spokesperson Ray Golden, additional actions must still be taken before the shipment can occur, including notifications and additional discussions with specific parties and mobilization of the reactor vessel shipment contractors and vendor personnel. There is no set schedule at this time for when the vessel will leave the site.
