Characterization of Radioactive Waste Drums by Non Destructive Gamma Spectrometry

Assay of the radioactive content of waste drums is important for inventory and waste disposal purposes. The sampling of the drum content is a difficult, time and labor consuming procedure, involving special radiation protection considerations. On the other hand the characterization of waste drums containing radioactivity by measuring the drum as a whole (without opening) offers overall simplici...

NON-DESTRUCTIVE THERMAL DAMAGE CHARACTERIZATION OF CORDIERITE-MULLITE REFRACTORIES

Abstract: Refractory materials containing cordierite (2MgO.2Al2O3.5SiO2) and mullite (3Al2O3.2SiO2) are used as support in furnaces, because of their low thermal expansion properties which confer them a very good ability to thermal shock resistance. Composed of two phases presenting very different CTE (1.5–3×10-6 for cordierite and 4–6×10-6 K-1 for mullite), these materials can develop damag...

Further Development in Characterization of Radioactive Waste Drums by Non Destructive Gamma Spectrometry at GRR-1

A non destructive technique based on gamma spectrometry and application of the Monte Carlo method for detector efficiency calibration, was used to assay radioactive content waste drums. Exploranium GR-130 miniSPEC portable gamma ray spectrometer was used to externally monitor radioactive waste drums containing ion exchange resin waste from the water demineralization system of GRR-1 open pool-ty...

Non-destructive characterization of smart CFRP structures

Smart materials based on carbon-fibre-reinforced plastic (CFRP) with embedded PZT sensors and actuators are expected to be a favourite composite for vibration damping and noise reduction. Due to the wide variety of physical properties of the components, various damage mechanisms may reduce or even remove the sensing and actuating capabilities of the piezoceramic material. Comprehensive non-dest...
