[en] A significant number of nuclear power plants will have to be decommissioned over the next few years as a result of earlier and planned shut downs initiated by plant aging, political decisions and unfortunate events. The decommissioning process is challenging for all stakeholders due to uncertainties and risk associated with decisions on applied technologies, organisational changes, and management of human factors. In this study we investigated how concepts, enabled by advanced information technologies, can be applied for providing continuity between different phases of the decommissioning work process and life cycle of the installation, as well as stakeholders involved in on-going and future decommissioning projects.
[en] This paper sets out the findings of a two-year research project to explore the impact of nuclear security ‘train the- trainer’ professional development courses (PDCs). Drawing on extensive empirical fieldwork, the research identifies a number of lessons learned from the experience. These range from the challenges associated with integrating nuclear security into academic courses and training programmes, to the significance of the interactive elements forming part of the PDC process. On a larger scale, the research finds that the PDC process has served as a force multiplier for an emerging community of practice in nuclear security education. (author)
[en] Managing essential knowledge as a strategic organizational asset is a factor of upmost relevance in today’s Nuclear Organizations. The author considers evident that competencies are critical carriers of Knowledge. As such the use of an appropriate competency model could be the most effective way to capture the present reservoir of explicit and tacit Knowledge of specific functions or organizational areas. Besides we could use them into new or other redesigned functions or determine the needs of specific competencies for future positions. Therefore, appropriate competency models or systems have to be developed or updated in each Nuclear Organization since it is a fundamental system for managing more effectively and efficiently the present nuclear human capital and a very significant system to forecast the evolving competence required in management, technical, scientific and safety areas to keep a continuous and highly competent nuclear workforce. On the other hand, competency based management models or systems would not achieve the expected results if they are not fully designed and integrated within the strategic organizational infrastructure of the related nuclear organization. This paper is expected to provide a wider view and practical reflexions on organizational transformation issues and the benefits of using an integrative competency model in the nuclear industry. Particularly, a clear insight of an empiric model Strategic Organizational Transformation process © and Integrative Management practices on how to re-align strategic issues with top management processes and building organizational capacity through effective competency based management for the sustainable transformation of Nuclear Organizations.

[en] While the nuclear power industry works towards reinforcing its safety and regaining the public’s support post-Fukushima, it is also faced with another challenge that affects its day-to-day activities: a rapidly aging workforce. Statistics show that close to 40% of the current workforce in the nuclear power industry will retire within the next five years. For newcomer countries, the challenge is even greater, having to develop a completely new workforce. The workforce replacement effort introduces nuclear newcomers of a new generation with different backgrounds and affinities. Major lifestyle differences between the two generations of workers result, among other things, in different learning habits and needs for this new breed of learners. Interactivity, high visual content and quick access to information are now necessary to achieve a high level of retention. To enhance existing training programmes or to support the establishment of new training programmes for newcomer countries, L-3 Communications MAPPS Inc. (L-3 MAPPS) has devised learning tools to enhance these training programmes focused on the “practice-by-doing” principle. L-3 MAPPS has coupled 2-D and 3-D computer visualizations with high-fidelity simulation to bring real-time, simulation-driven animated components and systems allowing immersive and participatory, individual or classroom learning. The use of technology, such as learning tools, should be a key element of a successful and robust knowledge management programme. (author)
[en] The main objectives of decommissioning are to place nuclear facilities, that have reached the end of their useful lives in such a condition that they pose no unacceptable risks to the public, to workers or to the environment, and to reuse facilities and sites for new purposes. For that, attached particular importance to reducing risks for people. as a result appropriate consideration of health and safety. During the design stage, which covers concept detailed design specification (drawings, calculations, specifications, etc) for maximum potential for reducing risks, by application of the principles of safer design.
[en] Calandria tubes (CT) of the nuclear reactor sag over time due to the weight and heat loads. The CT Sag has to be monitored for the safe operations of the reactor. The typical sag size is of the order of 20 -30 mm. Presently the sag measurements are done using ultrasonic probe, LVDT and inclinometer. Measurement probes of these measuring instruments are highly prone to damage because of high radiation levels present in the CT. Also, all the methods are contact in nature. Here, we propose a non-contact sag measurement technique based on the principle of Shadowgraphy using an expanded He-Ne laser beam. The technique can measure the sag of the CT within an accuracy of ± 0.5 mm. (author)
[en] Regulatory changes as well as persistent threats are major drivers in the field of nuclear security. To respond to these challenges the International Atomic Energy Agency (IAEA) has called for universities to set up master programs in nuclear security. Therefore the Institute for Security and Safety at the Brandenburg University of Applied Sciences is currently setting up an innovative Master in Nuclear Security (MiNS). MiNS will be conducted as a distance learning program and its curriculum will be based on the results of the IAEA’s Nuclear Security Series No.12 (NSS 12) on education in nuclear security. This article aims at providing a comprehensive overview over the Master in Nuclear Security. (author)
[en] Radiation has been used to nondestructively examine samples for over a century. Neutral particles such as ionizing photons and neutrons, in particular, have wavelengths that allow the internal structure of cm-scale objects to be observed through processes such as radiography and tomography. A related technology, backscatter scanning, is shown to be useful as a crude imaging modality that is appropriate for certain applications. This presentation considers the problem of detecting defects below the surfaces of engineered structures. Engineered structures are designed and built to exacting standards, unlike biological systems which vary one from another. A possible way of constructing images from backscatter responses obtained as a probe scans, in discrete steps, over the surface of an engineered structure is presented. The technique involves template-matching and use of a figure of- merit, and its standard deviation, calculated from a set of responses obtained over a “window” that is allowed to roll over the surface being investigated. Two applications of this backscatter scanning technique are considered: hidden corrosion within a lap joint between two layers and cracks that emanate from fastener holes. Possible reactor safety applications also are discussed. (author)
[en] Collaboration of universities and academics with the regulatory body, the operator and other stakeholders to enhance nuclear security is mandatory for success of efforts and activities of nuclear security. For newcomer countries, training in the field of nuclear security focuses mainly on providing the basic training requirements and on enhancing the nuclear security culture. The availability of qualified specialists in the field nuclear security is essential for the establishment of a nuclear security regime in different countries. Unlike operating nuclear power countries, nuclear power newcomers have a limited pool of nuclear security experts. Those experts are needed in industry, regulatory body, educational institutions and training centers. Therefore, an HRD action plan should be developed and implemented to ensure future sustainability. A significant part of the HRD plan can be provided via universities with experience in safety and security. Such universities can provide education and training for current and future workforce and improve nuclear security tools, properties and characteristics through research. In Egypt, there are two universities currently working on nuclear security education and training; and can be considered as a role model for collaboration between academia and nuclear regulator and operator in the context of nuclear security; Alexandria University and Suez Canal University. Both universities have established two memorandum of understanding with the ENRRA for cooperation in nuclear security education and training. Both universities are also active participants in INSEN (International Nuclear Security Education Network). This paper discusses the collaboration between Alexandria University and Suez Canal University with the Egyptian Nuclear and Radiological Regulatory Authority (ENRRA) and the role they play in nuclear security education; via providing programmes, courses and modules, training through programmes and workshops and graduate research (Mater and Ph.D. levels).
