Radiofrequency Identification

A temperature-monitoring system based on radiofrequency identification (RFID) has been developed for extending the maintenance period of the nuclear material packaging for storage and transportation. The system consists of tags, readers, and application software. The tag, equipped with a temperature sensor, is attached to the exterior of a package. The application software enables remote reading, via radio waves, of the temperature from the sensor in the tag. The system reports any temperature violations immediately via e-mail or text message, and/or posts the alarm on a secure website. The system can monitor thousands of packages and record individual temperature histories in a database. The first type of packaging that will benefit from the RFID technology is Model 9977, which has been certified by the U.S. Department of Energy (DOE) to ship and store fissile materials such as plutonium and uranium. The recorded data can be correlated to the temperature of the containment O-ring seals, based on the decay heat load of the contents. Accelerated aging studies of the Viton® GLT O-rings have shown that temperature is one of the key parameters governing the life of the O-ring seals, which maintain the integrity of the containment boundary of the package. Use of the RFID temperature-monitoring system to verify that the surface temperature remains below a certain threshold will make it possible to extend the leak-test period of the package from one year to up to five years. The longer leak-rate testing interval will yield a cost savings of up to $10,000 per package over five years. This work was conducted by Argonne National Laboratory in support of the DOE Packaging Certification Program, Office of Environmental Management, Office of Packaging and Transportation (EM-63).

Scattering Signal

The reliability of busway in high current state is closely related to its temperature. So effectively monitoring temperature is the key issue to ensure the busway work safely. Because of the constraints such as high voltage and strong electromagnetic fields, traditional temperature measurement system can not meet the requirements. A distributed busway temperature monitoring system is designed in this paper based on the temperature effect of fiber Raman scattering signal. Arithmetic average, wavelet noise reduction and low-pass filter combination of data processing is used to overcome the very low SNR. Experiments show that the system can measure the temperature of 1km busway effectively. Temperature resolution can achieve 3°C.
