The Department of Energy (DOE) designated the Advanced Test Reactor (ATR) as a National Scientific User Facility (NSUF) in April 2007 to support U.S. leadership in nuclear science and technology. By attracting new research users-universities, laboratories, and industry-the ATR NSUF facilitates basic and applied nuclear research and development, further advancing the nation's energy security needs. A key component of the ATR NSUF effort is to prove new in-pile instrumentation techniques that are capable of providing real-time measurements of key parameters during irradiation. To address this need, an assessment of instrumentation available and under-development at other test reactors was completed. Based on this review, recommendations were made with respect to what instrumentation is needed at the ATR; and a strategy was developed for obtaining these sensors. In 2009, a report was issued documenting this program's strategy and initial progress toward accomplishing program objectives. In 2009, a report was issued documenting this instrumentation development strategy and initial progress toward accomplishing instrumentation development program objectives. This document reports progress toward implementing this strategy in 2010.

The Department of Energy (DOE) designated the Advanced Test Reactor (ATR) as a National Scientific User Facility (NSUF) in April 2007 to support U.S. leadership in nuclear science and technology. By attracting new research users -universities, laboratories, and industry -the ATR NSUF facilitates basic and applied nuclear research and development, further advancing the nation's energy security needs. A key component of the ATR NSUF effort at the Idaho National Laboratory (INL) is to design, develop, and deploy new in-pile instrumentation techniques that are capable of providing real-time measurements of key parameters during irradiation. To address this need, an assessment of instrumentation available and under-development at other test reactors was completed. Based on this initial review, recommendations were made with respect to what instrumentation is needed at the ATR, and a strategy was developed for obtaining these sensors. In 2009, a report was issued documenting this program's strategy and initial progress toward accomplishing program objectives. Since 2009, annual reports have been issued to provide updates on the program strategy and the progress made on implementing the strategy. This report provides the 2012 update.As reported in this document, significant accomplishments occurred in several instrumentation development and deployment areas during 2012. Specialized INL-developed sensors for real-time detection of temperature and thermal conductivity are not only being provided to NSUF reactors at INL and at the Massachusetts Institute of Technology, but are also being provided to the Commissariat à l'Énergie Atomique et aux Energies Alternatives (CEA) in France and to the Institute for Energy Technology/Halden Reactor Project (IFE/HRP) in Norway for evaluation. High Temperature Test Laboratory (HTTL) staff are also involved in expanding options for peak temperature sensors, such as melt wires and silicon carbide temperature monitors, and integral fluence sensors, such as activation foils and flux wires available to our users. On-going tasks to deploy real-time length and flux detection sensors are continuing. A test rig for evaluating creep specimens is now ready for use in the newly reactivated ATR pressurized water loop and efforts have been initiated to develop a crack growth test rig. In addition, several tasks evaluating 'advanced' technologies, such as fiber-optics based length detection and ultrasonic thermometers, were initiated.
