“…In recent years, NRG has been involved in several internationally-sponsored tests for advanced reactor fuels. 81 In particular, this reference discusses recently completed and ongoing campaigns to evaluate gas reactor fuel elements (the HFR-EU1bis and HFR-EU1 tests), gas reactor fuel coating materials (the PYCAASSO I and II tests), liquid metal fast reactor and accelerator driven system fuel tests (CONFIRM, FUJI), transmutation fuel tests (HELIOS irradiations), and advanced fuel cycle (e.g., U-Pu and Th-U cycle tests).…”

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.

“…The normal operating power is 45 MW. Special irradiation rigs have been developed and are regularly used for testing fuel samples under conditions which are representative of the current conditions of the power plant [2], [4]. A new irradiation test is planned to remain in the core at least 21 cycles to achieve a target burn-up of 11.5% FIMA.…”

Within the European High Temperature Reactor Technology Network (HTR-TN) and related projects a number of HTR fuel irradiations are planned in the High Flux Reactor Petten (HFR), The Netherlands, with the objective to explore the potential of recently produced fuel for even higher temperature and burn-up. Irradiating fuel under defined conditions to extremely high burn-ups will provide a better understanding of fission product release and failure mechanisms if particle failure occurs. After an overview of the irradiation rigs used in the HFR, this paper sums up data collected from previous irradiation tests in terms of thermocouple data. Some R&D for further improvement of thermocouples and other on-line instrumentation will be outlined.
