“…The radiation effect on the sensitivity of piezoelectric transducer has been investigated and reported in several papers [27][28][29][30][31]. For high temperature and extended operation two approaches to design have been investigated: a) waveguide based transducer and b) fully immersion transducer.…”

“…Changes in both the mean frequencies and response up to 78% were reported. More recently, Augereau et al 94 has reported both gamma and neutron irradiations on piezoceramics, including neutron irradiations with a fluence of 1.6 x 10 21 n/cm 2 for 150 days. Although some irreversible effects were seen, variations in resonant frequency were less than 1%.…”

“…Several studies, as indicated above, have examined the performance of PZT and other lead based piezoelectrics when exposed to radiation and high temperatures. 85,92,[94][95][96] The lead-based piezoelectric have relatively low Curie temperatures (~ 320°C / ~610°F). Manufacturers generally recommend a maximum operating temperature of half the Curie temperature (~160°C /~ 320°F).…”

SUMMARYNew and enhanced nuclear fuels are a key enabler for new and improved reactor technologies. For example, the goals of the next generation nuclear plant (NGNP) will not be met without irradiations successfully demonstrating the safety and reliability of new fuels. Likewise, fuel reliability has become paramount in ensuring the competitiveness of nuclear power plants. Recently, the Office of Nuclear Energy in the Department of Energy (DOE-NE) launched a new direction in fuel research and development that emphasizes an approach relying on first principle models to develop optimized fuel designs that offer significant improvements over current fuels. To facilitate this approach, high fidelity, real-time, data are essential for characterizing the performance of new fuels during irradiation testing. A three-year strategic research program has been initiated for developing the required test vehicles with sensors of unprecedented accuracy and resolution for obtaining the data needed to characterize three-dimensional changes in fuel microstructure during irradiation testing. When implemented, this strategy will yield test capsule designs that are instrumented with new sensor technologies for irradiations at facilities primarily relied upon by the Fuel Cycle Research and Development (FCR&D) program, the Advanced Test Reactor (ATR) and the High Flux Isotope Reactor (HFIR). Prior laboratory testing, and as needed, irradiation testing of sensors in these capsules will have been completed to give sufficient confidence that the irradiation tests will yield the required data.From the onset of this instrumentation development effort, it was recognized that obtaining these sensors must draw upon the expertise of a wide-range of organizations not currently supporting nuclear fuels research. Hence, a draft version of this document was developed to provide necessary background information related to fuel irradiation testing, desired parameters for detection, and an overview of currently available in-pile instrumentation. Then, a workshop was held in which U.S. and foreign experts from fuels, irradiation, and instrumentation fields participated. Prior to this workshop, copies of a draft version of this document were distributed to participants to stimulate expert interactions at this meeting. During the workshop, candidate sensor technologies identified in this document were discussed and ranked by the experts using agreed upon criteria. The final version of this document describes the consensus reached during the workshop with respect to recommendations for the path forward for accomplishing the goals of this research program.Based on the activities completed to develop this strategic plan, it is recommended that the FCR&D instrumentation development program be initiated as a three year program that includes the following three tasks:• Ultrasonics-Based Evaluations -In this task, laboratory evaluations and necessary irradiations will be completed to demonstrate the viability of this technology for in-pile applications.

“…The proposed test temperature will be approximately 400 o C. It is proposed that the test exceed fast neutron fluences of prior piezoelectric transducer irradiations (e.g., > 1x10 21 n/cm 2 [25]). In order to observe rapid changes at relatively low fluences, it is proposed to start the test with the reactor slowly ascending to power.…”

Abstract-Ultrasonic technologies offer the potential for high accuracy and resolution in-pile measurement of numerous parameters, including geometry changes, temperature, crack initiation and growth, gas pressure and composition, and microstructural changes. Many Department of Energy-Office of Nuclear Energy (DOE-NE) programs are exploring the use of ultrasonic technologies to provide enhanced sensors for in-pile instrumentation during irradiation testing. For example, the ability of single, small diameter ultrasonic thermometers (UTs) to provide a temperature profile in candidate metallic and oxide fuel would provide much needed data for validating new fuel performance models.Other efforts include an ultrasonic technique to detect morphology changes (such as crack initiation and growth) and acoustic techniques to evaluate fission gas composition and pressure. These efforts are limited by the lack of existing knowledge of ultrasonic transducer material survivability under irradiation conditions. To address this need, the Pennsylvania State University (PSU) was awarded an Advanced Test Reactor National Scientific User Facility (ATR NSUF) project to evaluate promising magnetostrictive and piezoelectric transducer performance in the Massachusetts Institute of Technology Research Reactor (MITR)up to a fast fluence of at least 10 21 n/cm 2 (E> 0.1 MeV). This test will be an instrumented lead test; and real-time transducer performance data will be collected along with temperature and neutron and gamma flux data. By characterizing magnetostrictive and piezoelectric transducer survivability during irradiation, test results will enable the development of novel radiation tolerant ultrasonic sensors for use in Material and Test Reactors (MTRs). The current work bridges the gap between proven out-of-pile ultrasonic techniques and in-pile deployment of ultrasonic sensors by acquiring the data necessary to demonstrate the performance of ultrasonic transducers.
