This article describes current status and some future issues in education and training of operators for nuclear power plants. Based on the lessons learned from the accidents at Fukushima-Daiichi nuclear station, the regulation for Japanese nuclear power plants has been tightened. Following the tightening of regulation, the education and training of operators has been improved to take suitable counter operations in a design extension event as well as supposed abnormal plant situations. First, this article describes the outline of the new regulatory standards. Then, some examples of the education and training of operators, mainly the education and training menus at BWR Operation
Training Center Corporation, are introduced. Some new activities at Japan Nuclear Safety Institute after the accidents are also introduced. A training menu to improve non-technical skills is described as a new trend of education and training of operators. This article concludes to point out some issues to be considered to make the education and training of operators more effective.
The research group in JSQC for high reliability and safety has already proposed totally 6 kinds checklists in order to confirm and prevent the unfaithful manners inherent in quality management. To make up the checklists, many contents were argued by research members for a long time. Fundamental and important discussion contents were summarize to 10 topics. First half of them have already been reported. They would be useful to understand proposed checklists. Second half of them are conversationally described in this paper. They would contribute to activate quality management by utilizing checklists.
The meetings of Technometrics research group take place once a quarter. In the meetings, we
discuss mathematical statistical methodology and data analysis on various topics of Technometrics.
The results produced by the discussion of this research group are opened in various conferences or
journals such as Journal of the Japanese Society for Quality Control. In this report, 5 topics recently
discussed in Technometrics research group are introduced. We appreciate it if the readers generate
interests on our activity by this report.
Agile software development is one of the keys to achieving digital transformation, but it is not as popular in Japan as in other countries. In Japan, it is considered difficult to perform project management and quality management for agile software development, and this has been a barrier to its spread in Japan. This paper presents an essential approach to project management and quality management when implementing agile software development, and
shows its differences from traditional waterfall development or other iterative development. Based on this, we demonstrate how to plan the quality of the software to be developed and how to build its quality, and show that quality
management is also possible in agile software development.
TQM in corporate management is considered to be one of the best practices. TQM is especially popular in the manufacturing industry, but it’s time to think about what it should be in the future. This paper analyzes the manufacturing industry from the viewpoint of a business model and considers the future. It will also analyze the globally successful GAFA from the viewpoint of a business model and explore its secrets. Based on these results, it proposes a business model for the spread of TQM.
The power of test of the treatment effects will get higher when sum of squares of degree of freedom of more than 2 is divided into each component having degree of freedom of 1 by means of orthogonal contrasts.
The factor effects obtained from experimental data such as orthogonal array experiments can be considered in detail by establishing contrasts based on the own intrinsic technology. Thus, this approach can lead to the significant conclusion in detail and practically.
This approach is better for power of test than general analysis of variance as results of the numerical simulations.
In case of saturated designs, usual analysis of variance is difficult. On the other hand, this approach is appliable because the degree of freedom of error is increasing as the sum of squares of degree of freedom of 1 increases instead of the sum of squares of degree of freedom of more than 2.
Applying this approach will be able to support applications to practical technical affairs including treatments having beyond three levels. The profit of this approach is big enough for experimenters.
