The U.S. Department of Energy (DOE) designated the Advanced Test Reactor (ATR) as a National Scientific User Facility (NSUF) in April 2007. This designation allows the ATR to become a cornerstone of nuclear energy research and development (R&D) within the U.S. by making it easier for universities, the commercial power industry, other national laboratories, and international organizations to conduct nuclear energy R&D. The mission of the ATR NSUF is to provide nuclear energy researchers access to world-class facilities, thereby facilitating the advancement of nuclear science and technology within the U.S. In support of this mission, hot cell laboratories are being upgraded. These upgrades include a set of lead shielded cells that will house Irradiated Assisted Stress Corrosion Cracking (IASCC) test rigs and construction of a shielded laboratory facility. A primary function of this shielded laboratory is to provide a state of the art type laboratory facility that is functional, efficient and flexible that is dedicated to the analysis and characterization of nuclear and non-nuclear materials. The facility shall be relatively easy to reconfigure to provide laboratory scale hot cave space for housing current and future nuclear material scientific research instruments.
