FAST NON DESTRUCTIVE EVALUATION OF LARGE STRUCTURES WITH LOSS ANGLE LOCKIN THERMOGRAPHY Record Control Number : 42480 Quality Validation Date : 1997-08-12 Update Date : 1999-08-17 Title : FAST NON DESTRUCTIVE EVALUATION OF LARGE STRUCTURES WITH LOSS ANGLE LOCKIN THERMOGRAPHY Subject Index Code : Education, Training, Scientific Research General Information : Research objectives and content Acoustic waves propagating in a material undergo hysteretical losses of power with consequent generation of heat (loss angle effect) . Loss angle lockin thermography is able to provide images of internal defects based on the heat generated by loss angle effect. Corroded areas, delaminations, cracks can be easly visualized. The aim of this project is to develop and test loss angle lockin thermography as a powerful non destructive evaluation technique, whose preliminary results showed to be extremly promising for rapid inspection of large surfaces. This technique has also shown to be able to reveal irnportant defects not detectable with others techniques, marking a significant progress in the field of non destructive testing. Training content (objective, benefit and expected impact) The candidate will benefit from an experience in a laboratory endowed with the newest and most sophisticated techniques. Being involved in the development of this new technique will provide the candidate with a broad experience in ultrasonics, thermography, new and advanced materials, mechanics of fracture and corrosion. This experience will also put the candidate in direct contact with the research centers of industries that already showed their interest. Links with industry / industrial relevance (22) ABB has provided samples with defects not detectable with other techniques than loss angle lockin thermography and showed a great interest in the development of this new technique. Branson, an important company producing ultrasonic welding machines, has shown a greet interest and is willing to cooperate in the project. Industries like Eurocopter, MTU, and others, involved in non destructive testing of structures, showed interest in this technique. AGEMA is naturally interested in a new development involving infrared cameras.

CONVENTIONAL GAMMA SCANNING IS ONE OF THE MOST WIDELY USES NON-DESTRUCTIVE TESTING METHODS FOR ROUTINE QUALITY CHECKING OF RADIOACTIVE WASTE DRUMS. ITS RANGE OF APPLICATION COVERS RAW WASTE PRIOR TC CONDITIONING AS WELL AS CONDITIONED WASTE PRIOR TO DISPOSAL OR INTERIM STORAGE. THE ACCURACY AND RELIABILITY OF THE RESULTS OF CONVENTIONAL GAMMA S Q NNING MEASUREMENT' DEPEND STRONGLY ON THE FULFILYENT OF THE ASSUMPTION THAT THE GAMMA ATTENUATION IN THE WASTERMATRIX CAN BE PROPERLY CORRECTED. SUCH CORRECTIONS ARE USUALLY PERFORMED ON THE BASIS OF 'A PRIORI' KNOWLEDGE OF THE ATTENUATION PROPERTIES OF THE WASTE OR BY SIMPLY WEIGHING THE DRUM AND CALCULATING THE AVERAGE DENSITY. THESE ASSUYPTIONS ARE ONLY FILLED FOR WELL DEFINED WASTE PACKAGES. IN THE CASE OF HETEROGENEOUS ACTIVITY OR MATRIX DISTRIBUTIONS UNCERTAINTIES WILL BE INTRODUCED INTO THE MEASUREMENT RESULTS THAT CAN LEAD TO SIGNIFICANT ERRORS IN THE ACTIVITY DETERMINATION ESPECIALLY FOR WASTE WITH HIGHER MATRIX DENSITY. TO OPTIMISE CONVENTIONAL GAMMA SCANNING IT IS NECESSARY TO CALCULATE AND TO REDUOE THESE SOURCES OF ERRORS AS GOOD AS POSSIBLE. THIS CAN BE ACHIEVED BY APPROPRIATE CORRE( TION TECHNIQUES FOR GAMMA ATTENUATIONS LIKE THE YETHOD OF TRANSMISSION CORRECTED GAMMA SCANNING. IN THE PROPOSED WORK PROGRAMME AN IMPROVED GAMMA SCANNING SYSTEM WTTT BE DESIGNED AND SET-UP BASED ON TRANSMISSION CQRRECTION. THE SYSTEM SET-UP WILL BE DONE BY UPGRADING EXISTING Y-SCANNERS (TWO SCANNERS ARE ENVISAGED) SO THAT MEASUREMENTS ON REAL WASTE DRUMS CAN BE CARRIED OUT. THE MAJOR UNCERTAINTIES AND POSSIBLE ERRORS OF GAMMA SCANNING MEASUREMENTS WILL BE EVALUATED AND THE PERFORYANCE OF THE IMPROVED SCANNING TECHNIQUE WILL BE QUANTIFIED COMPARED TO CONVENTIONAL GAMMA SCANNING. AS A RESULT OF THE PROJECT RECOMMENDATIONS WTTT, BE FORMULATED ON HOW TO PERFORM GAMMA SCANNING MORE ACCURATELY FOR CERTAIN RANGES OF APPLICATION. THESE GUIDELINES - WHICH COULD BE PUBLISHED AS 'EC-GUIDELINES FOR GAMMA SCANNING OF WASTE PACKAGES' - WITT HELP THE RESPECTIVE PEOPLE WHO PERFORM GAMMA MEASUREMENTS TO SET,FCT THOSE TECHNIQUES WHICH ARE BEST SUITED FOR A SPECIFIC QUALITY INSPECTION TASK, TO ESTIMATE POSSIBLE ERRORS AND TO SELECT APPROPRIATE MEASURES TO REDU OE UNCERTAINTIES. THE RESULTS OF THE WORK PROGRAMME WILL BE OF INTEREST FOR NEARLY ALL APPLICATIONS IN WHICH NONDESTRUCTIVE GAMMA ASSAY SYSTEMS ARE USED TO MEASURE VOLUMETRIC RADIOACTIVE WASTE PACKAGES.

To overcome the limitations of the existing systems and satisfy user needs of lower exploitation / production costs and higher inspection process reliability the development of a radioscopic inspection system based on a new multiline detector achieving the image quality of film radiography is being developed: a high resolution (up to approx 50 mm) and high sensitivity (high contrast: 1% in the Indicator of Quality Image IQI) Time Delay Integration (TDI) X ray detector (based on a multiple line CCD, packaged in a light and small volume) allowing speed inspection up to approx 60 mm/s. The inspection system will also have the possibility to realize a fusion between X Ray and ultrasonic data already available on the industrial site allowing a very high reliability of the whole weld testing.The NDT prototype system for filmless Real Time Radiography (RTR) developed in the project will be used to evaluate and prove performance, firstly in a pipe production factory for inspection of spiral seam welds and secondly in offshore pipe laying operations for circumferential weld inspection in arduous conditions. Advanced TDI detector technology and data fusion algorithms could also be applied to other real time digital inspection applications (e.g. food inspection, digital medical imaging for high resolution radioscopy, shipbuilding, energetic, nuclear, ...) . In pipe production applications, the introduction of the filmless RTR system could reduce the scrap rate at the X ray inspection stage from the present 20% to a few %. The possibility of 100% weld inspection allowed by the fast RTR together with the X Ray and US data fusion will allow a reduction of inspection uncertainty (reduced number of false defect alarms) from 50% using only US to nearly 0%. The possibility of film replacement will reduce cost of consumables and allow high inspection and high production speeds. In offshore (onshore) pipeline inspection, the availability of a RTR system would enhance the inspection quality, provide real time evaluation thus increasing the speed in pipe laying by approx 30%, with consequent major costs savings, and minimize the chances of ruptures that can be very expensive to repair. Substantial improvements in environmental impact are also foreseen thanks to higher pipe inspection reliability (e.g. avoiding oil spill from pipes) and potential suppression of processing chemical with the envisaged film replacement. The main areas of innovation are as follows: The introduction of an effective Real Time Radiography inspection system/ methodology for film replacement A new X ray detector capable of real time inspection with digital data output being scanned continually over the weld. A high speed image processing system, capable of correcting the detector image in real time and with a high data rate detecting the defects, and displaying / storing the results on a standard PC. Interface software to enable ultrasonic data to be displayed synchronously with the x ray data, and fused in case of a defect signal, to allow the system to benefit from the advantages of both methods in an on line testing operation. The technological effort necessary to develop the detector and the image processing system and data fusion brings together major European specialists in each domain, with major industrial partners, small and medium entreprises, educational and research institutes, covering the complete range of roles and capacities from basic academic research through development, production, distribution, to the end user, each partner bringing specific and complementary competence and experience to obtain the desired results in time and within the foreseen budget.The consortium is also highly transnational, with partners from four different countries from Northern to Southern Europe.
