AbstractThe effect of geographical distance on the extent of socioeconomic impacts of the Dukovany nuclear power plant in the Czech Republic is assessed by combining two different research approaches. First, we survey how people living in municipalities in the vicinity of the power plant perceive impacts on their personal quality of life. Second, we explore the effects of the power plant on regional development by analysing long-term statistical data about the unemployment rate, the share of workers in the energy sector and overall job opportunities in the respective municipalities. The results indicate that the power plant has had significant positive impacts on surrounding communities both as perceived by residents and as evidenced by the statistical data. The level of impacts is, however, significantly influenced by the spatial and social distances of communities and individuals from the power plant. The perception of positive impacts correlates with geographical proximity to the power plant, while the hypothetical distance where positive effects on the quality of life are no longer perceived was estimated at about 15 km. Positive effects are also more likely to be reported by highly educated, young and middle-aged and economically active persons, whose work is connected to the power plant.

Flaw Detection Probability

This study was performed to clarify the effects of flaw detection probability on piping reliability of a nuclear power plant. Stress-corrosion cracking (SCC) is still sporadically detected in austenitic stainless steel piping in Japanese BWR plants. The suitability for continued service of cracked pipes is basically evaluated by using the “Rules on fitness -for service for nuclear power plants.” Here future inspection rules are employed. However, the possibility of undetection of existing cracks and that of inaccurate measurements cannot be eliminated in UT-based inspection. Thus a probabilistic fracture mechanics (PFM) analysis was carried out referring measured flaw size, and the reliability of piping was evaluated considering the possibility of undetection of existing cracks and that of inaccurate measurements. The results of the analysis indicate that, if the interval and quality of the inspection are maintained at a certain specified level, the possibility of undetection of existing cracks and that of inaccurate measurements less affect failure probability.

Digital Imaging Technology

In Radiography Testing (RT) that is an important nondestructive testing as the quality control, the digital imaging technology rapidly provides advancement. The digital imaging technology is more effective than the film method on an environmental side and the cost side, such as unnecessary of the film storage and a chemical treatment by digital output. Especially, in the medical field, the advancement by the digitalized image data processing is remarkable, and it is attempted the upgrade of the inspection technology. However, RT that uses the high-energy radiation and the fast film is a main current in an industrial field, and it has not arrived at digitalization yet. Therefore, in an industrial RT, digitalization is expected and the examination standardization is required also in ASME, JSME, and JIS. We, Mitsubishi Heavy Industries (MHI), studied an applicability of Computed Radiography (CR) to Non-Destructive Examination (NDE) for welds of piping and thick wall component in nuclear power plant. At first, MHI researched image quality of CR for piping. In this research, it was confirmed that the images of testing results by CR method are equivalent to that by film method in terms of visibility of IQI (Image Quality Indicator) and detection performance of welding defects. And we founded the optimized shooting conditions for piping. Second, MHI researched image quality of CR for thick wall component. In the result, the noise shown in fig.1 was occurred on CR image when the thick wall component such as pressure vessel is radiographed with high energy. It is speculated that the primary cause of this noise is the scattered X-ray effect (shown in fig.2). Therefore it is necessary to investigate the effect of the scattered X-ray on CR image. In this study, to reduce the scattered X-ray effect on CR image, we investigated the effect of 1) screen, 2) screen + filter on image quality of CR for thick wall component. And we studied the optimized shooting conditions and parameters for thicker component than piping to aim for more application. Finally, we applied CR to the pipings and components for nuclear power plant with the optimized shooting conditions and parameters.

Lessons from the Fukushima-Daiichi nuclear power plant accident emphasize the difficulties for restoring the socio-economic activities in the affected areas. Among them, a series of radioligical protection challenges were noted, in particular concerning the protection of employees, the securing of the production and the guarantee provided to consumers of the radiological monitoring of products to restore their confidence. Based on case studies reporting the experience of employers deploying their activities in affected areas, an analysis of these radiological protection challenges has been performed. Characterizing the radiological situation was not always straightforward for the managers. With the help of radiological protection experts, protective actions have been identified and specific efforts have been devoted to provide information to employees and their families helping them to make their own judgement about the radiological situation. Respecting the decisions of employees and developing a radiological protection culture among them have proved to be efficient for restoring the business activities. Continuing or restoring the production not always manageable. It requires to develop dedicated radiological monitoring processes to ensure the radiological protection of workers and the quality of the production. Re-establishing the link with the consumers and organising the vigilance on the long-term were necessary for companies to maintain their production or develop new ones. Deploying a socio-economic programme for ensuring the community resilience in affected areas requires the adoption of governance mechanisms respecting ethical values to ensure the overall objective of protecting people and the environment against the risks of ionizing radiation and contributing to provide decent living and working conditions to the affected communities. It is of primary importance to rely on the involvement of local communities in the elaboration and deployment of the socio-economic activities with due considerations for ensuring the integrity of the communities, and respecting their choices.

Design plays a leading role in the whole life cycle of nuclear power production, including site selection, design, manufacture, construction, operation and decommission. The quality of the design products directly affects the intrinsic safety of the nuclear power plant. The quality of final products in design process depends on a number of factors, including not only technology capability, but also the improvement of design quality assurance system, the capability and responsibility of the designers to nuclear safety, the thinking mode and working habit of the designers, and the extent of complete implementation of the review systems at all levels. These factors consequently affect the level of safety of the nuclear power plant. Nuclear power design industry is typical knowledge-intensive business, in which knowledge workers consist of essential assets to the enterprise. The article analyzes the asset structure and staff structure of nuclear power design industries in contrast with other industries, and discusses the contribution of knowledge workers to the development of the enterprise. This paper also tries to document the characteristics of knowledge workers in nuclear power enterprises. They are characteristic of superior income and welfare, high level education and ability, high specialization, and tacit knowledge. Based on these analyses, the article addresses four major principles in nuclear safety culture construction for nuclear power design enterprises as follows: 1. adopt motivation factors as major incentives, 2. emphasize self management, 3. management by objectives (MBO), 4. team work.
