The first European superconducting winding pack (WP) and the first set of coil cases [toroidal field coil cases (TFCC)] for ITER are going to be delivered in 2017. The TFCC are steel structures that provide structural integrity to the WP, contribute to neutron shielding capacity, provide support to operating forces, and offer interface connections with the rest of the ITER machine. The TFCC assembly is formed by four main parts: two sectors with U-shaped section and two closure plates, which, after being welded together, enclose the WP. Each TFCC weights about 150 t and presents a wall thickness from 60 to 120 mm. The presence of distortions when welding such thick structures is particularly problematic in these components, which require tight tolerances and include several interfaces with other parts of the machine. In order to compensate the distortions, extra material is present in the critical areas to allow postwelding machining. The amount of extra material has to be optimized to reduce machining time and therefore the cost of the manufacturing. Thus, the evaluation of the welding-caused distortions is essential in order to confirm the extra-material strategy. In this scenario, an experimental and simulation campaign has been set up to predict the deformation of the TFCC during welding. First, welding coupons were welded in representative configurations. Then, these data were used to build a preliminary finite element method (FEM) model tool, using ANSYS software, which was then benchmarked against a "blind test" coupon and three TFCC-like mock-ups of 1-m length. Finally, a full FEM model was constructed using the previous outputs and is currently under assessment to predict the deformation of the TFCC during the welding process. This paper presents the numerical and experimental activities carried out so far, being EnginSoft S.p.A. the developer of FEM models, SIMIC S.p.A. the responsible of welding processes and data acquisition, and Fusion for Energy the contractual and technical supervisor.

Background: Physical activity is recognized as an important tool in the prevention and treatment of osteoarthritis (OA). However, one on two Belgian citizens attains a minimum of 2.5 hours of moderate physical activity/week, and this proportion decreases to one on five in those aged >74 years. The promotion of physical activity in elderly OA-patients should target those factors that motivate or hinder physical activity in these persons. Aim of the study: to identify the motivators and barriers for physical activity in elderly OA-patients. Methods: First, Pubmed, Web of Science and Psychinfo were systematically screened using the keywords "Arthritis / osteoarthritis, physical activity / movement / exercise, motivation / adherence / barrier". Next, supplementary items were generated by a panel composed by a rheumatologist, a general practitioner, two physical therapist, two occupational therapists, a master in gerontology, a senior's sports coordinator (all showing clinical expertise in working with OA-patients) and a representative of the Flemish rheumatologic association. Finally, 17 elderly persons (10 female, 7 male, aged 65-80 years) suffering from osteoarthritis of the hip and/or knee participated in a semi-structured interview. Data obtained from literature search, panel discussion and interviews were analyzed from a qualitative approach by screening for motivators and barriers for physical activity. The Health Belief Model (Becker, 1974) was used as a theoretical framework for classifying the items. Results: Literature search resulted in 8 relevant articles (from which 2 reviews), generating 48 motivators and 69 barriers for physical activity in OA-patients. The expert panel discussion and semi-structured interviews generated respectively 117 and 97 motivators and 146 and 89 barriers for physical activity, which were either confirmatory or complementary to the items found in the literature. The items covered a wide range of physical, social and psychological motivators and barriers for physical activity. Inaddition, structural factors such as lifestyle and environmental factors such as 'the weather' were mentioned to influence the extent of physical activity. Apathy for exercise, depression, competitive social roles, pain, stiffness, low fitness-level, long-lasting sedentary life style, fatigue and co-morbidity were mentioned as barriers for physical activity. Common motivators were extrinsic motivation, social support, a good communication with the general practitioner and the autonomy to decide and/or choose. In literature, the expert panel and the interviews, an improved well-being, a better feeling and an improved health feeling were mentioned as motivators for physical activity. The role of the media was only emphasized by the experts and the elderly. Finally, the interviews demonstrate that elderly OA-patients are not equally informed concerning the purpose and benefits of physical activity. Conclusions: This study added supplementary motivators and barriers for physical activity in elderly OA-patients to those described in the literature, which are important to target when promoting physical activity in these patients. Based on the items generated in our study, a structured questionnaire will be developed and the relative importance of the different motivators and barriers for physical activity will be assessed on a large sample of OA-patients.
