Hanford's progress toward dry interim storage of K basin's spent fuel

摘要

This paper highlights the progress made toward removing the U.S. Department of Energy's (DOE) approximately 2, 100 metric tons of metallic spent nuclear fuel from two outdated K Basins on the banks of the Columbia River and placing it in safe, economic interim dry storage beginning in December 1997. A new way of doing business at the Hanford Site and within DOE is being used to achieve the fast-track schedule, , cost savings, and public cooperation needed for success. In February 1994, the Spent Nuclear Fuel (SNF) Project was formed to solve serious safety and environmental problems associated with corroding metallic spent fuel stored in 1950's vintage, leak-prone, water- filled concrete basins located within 365 meters (400 yards) of the last remaining unspoiled section of the Columbia River. Working together, the integrated project team focused on quickly getting the fuel out of the basins and into safe, dry storage. The team involved the public, government, regulators, and other stakeholders and forged a common understanding. The DOE transferred authority to the field to shorten approval times, and Site contractors reengineered processes to improve efficiency. Within nine months of creating the project, a plan was recommended to the DOE. It was approved on February 14, 1995. Further refinement, during the following six months, shortened the schedule even more and reduced costs by $350 million. The SNF Project is on a fast track. The K Basins Environmental Impact Statement was completed in only 11 months for only $1.3 million. Fuel and sludge samples were obtained from both basins and were sent to the laboratory for characterization and testing. The partially constructed Canister Storage Building (CSB), selected as the fuel storage facility, was redesigned, and construction was restarted saving over $17 million and cutting a year off the project schedule. With fuel removal beginning in December 1997, the SNF Project will have the fuel out of the K Basins and into economic sale storage four years ahead of the Tri-Party Agreement schedule, and it will save $100,000 a day in operating costs.
