Risk Based QC in Large Accelerator Project

Abstract: The Spallation Neutron Source (SNS) is an accelerator-based neutron source being built in Oak Ridge, Tennessee, by the U.S. Department of Energy (DOE). The SNS provides the most intense pulsed neutron beams in the world for scientific research and industrial development. An essential ingredient to the success of the SNS project was the single risk-based selection of quality controls used throughout the project for all aspects of the work and all equipment, including design and construction of the buildings, the R&D required for some features of the accelerator and its mercury target, and design and production of specialized accelerator and neutron technical equipment. A second tool used in common for all aspects of the project was the creation and completion of acceptance criteria forms. They provide insight into the successful achievement of important equipment parameters and the record of corrective actions. The participants will learn from a practical example that a large state-of-the art physics machine can be designed, built and commissioned successfully with a risk-based selection of quality controls that supports cost and schedule requirements of the project. Modification of an ISO 9001-2000 Quality Program to meet NQA-1 Requirements, and use of both Standards to Develop a Quality Assurance Plan for Compliance with DOE O 414.1C From The 33rd National Energy and Environmental Conference at Loews Ventana Canyon Resort in Tucson, AZ (August 27-30, 2006).
