INCEFA-PLUS delivers new experimental data and new guidelines for assessment of environmental fatigue damage to ensure safe operation of European nuclear power plants. Austenitic stainless steels will be tested for the effects of mean strain, hold time and material roughness on fatigue endurance. Testing will be in nuclear Light Water Reactor environments. The three experimental parameters were selected in the framework of an in-kind project during which the current state of the art for this technical area was developed. The data obtained will be collected and standardised in an online fatigue database with the objective of organising a CEN workshop on this aspect. The gaps in available fatigue data lead to uncertainty in current assessments. The gaps, will be targeted so that fatigue assessment procedures can address behaviour under conditions closer to normal plant operation than is currently possible. Increased safety can thus be assured. INCEFA-PLUS also develops and disseminates a modified procedure for estimating environmental fatigue degradation. This will take better account of the effects of mean strain, hold time and surface finish. This will enable better management of nuclear components, making possible the long term operation (LTO) of NPPs under safer conditions. INCEFA-PLUS is relevant to the NFRP1-2014 programme because: Present guidance originates from NRC. In Europe various national programmes aim to develop counter proposals allowing greater operational efficiency with at least comparable safety assurance. INCEFA-PLUS brings these programmes together through which a strong EU response to the NRC methodology will be obtained with improved safety assurance through increased lifetime assessment reliability. INCEFA-PLUS improves comparability of data from EU programmes because partner laboratories will do some tests on a common material under common conditions. Reduced assessment uncertainty will enable easier maintenance of safety

The EU Agency for Safety & Health is currently amending wind turbine standards (such as EN 50308) to ensure safer O&M tasks and increase the Probability Of Detection (POD) for wind turbine defects. ISO have also identified such issues, and in fact initiated the development of QA standards specifically tailored for the Condition Monitoring (CM) of wind turbines. Current CM systems are intrusive, and hence revoke the initial OEM warranty of drive-train components. The combination of industrial and legislative factors is the key driver behind the production of CMDrive: a bespoke and non-intrusive acoustic-analysis CM system, having a POD for drive-train defects of 90-98% within the range of operating powers. The requested grant of 2.5m will be required to validate and enhance the system, and initiate the commercialisation process. Growth in the wind services sector, as related to O&M and CM, is also compelling, as studies by Deloitte have shown that the corresponding market is estimated to increase from 5.2b to 10.8b by 2020, with a CAGR of 10%. The first generation of CMDrive shall be produced for wind turbines of 2.5MW or less; a next generation product, to handle larger turbines, has already been envisioned. The commercialisation strategy involves the segmentation of the wind turbine market into 3 initial customer tiers, is targeting WFOs and Independent Service Providers of CM within such tiers, and will position the product through a number of Unique Selling Points, which will be elaborated further in this proposal. The locations of the 5 partners, in addition to the global outreach of TWI and INESCO, are critical factors for launching the product by 2019. It is expected that CMDrives associated revenue streams (sales, services, licensing) will yield an estimated ROI of 1100%, and corresponding cumulative profits of 26m, over the 5 year forecast (20192023). INESCO will take lead of the sales, with the other partners benefiting by means of profit shares.

Current wind turbine condition monitoring methodologies can be time-consuming and a costly process and fail to achieve the reliability and operational efficiency required by the industry. For these reasons existing vibration-based Condition Monitoring System (CMS) usually fail to detect defects until they become critical. This project will show the applicability of the CMS enabling the prompt detection of defects. The proposal idea is to use this experience to deploy an existing system that: o Allows an early detection and identification of any developing defects on several components of the wind turbine such as blade cracking, slip-ring corrosion and shaft/bearing misalignment, thus helping to optimise the maintenance schedule. o Combine the use of several sensors in order to evaluate the overall operational condition of the turbines generator, gearbox bearings, main shaft and blades. o Use wireless sensor for rotating components monitoring using high performance powering and energy harvesting technologies. o Fuse and analyse the data obtained through the different sensors using a single SCADA system. Broadband radio transmission systems were developed to transmit the data from fixed or rotating frames to the ground without losing any signal resolution. The results indicate the feasibility of collecting AE signals from the rotating frame with acceptable level of noise in low to moderate wind speeds. Also other developments were executed in order to verify whether or not the noise level increases appreciably with wind speed and whether such signals can be filtered out. Application of CMSWind system: The Gearbox (including Main bearing, Yaw System, The hub) The Generator The Bolting One of the aims of this project is to develop new standards and procedures for applying offshore instrumentation and therefore providing generic developments and information of use to the whole Wind Energy and NDT industry.
