This paper presents an innovative safety training method based on digital ergonomics simulations and serious games, which are games that focus on education. Digital ergonomics is intended to disseminate the culture of safety among workers, while serious games are used to train the operators on specific safety procedures and verify their skills. The results of the experimentation in a real industrial environment showed that, compared to the traditional training methodology, multimedia contents and quantitative ergonomic analyses improve the level of attention and the awareness of the workers about their own safety. However, serious games turned out to be promising training tools with regard to standard operating procedures that are usually difficult or dangerous to simulate in a real working scenario without stopping production. Practitioner summary: Digital ergonomics and serious games are used to disseminate the culture of safety among the workers and for safety training. Our results show that the proposed methodology improves the level of attention and provides a better feedback about the actual skills of the workers than the standard educational strategies.

This work focuses on an innovative training methodology based on the use of Virtual ergonomics and “serious games” in the field of occupational safety. Virtual Ergonomics was chosen as an effective and convincing tool for disseminating the culture of safety among the workers, while a “serious game” was developed to train operators on specific safety procedures and to verify their skills. The results of the experimentation in a real industrial case study showed that, compared to the traditional training methodology, multimedia contents and quantitative ergonomic analyses improve the level of attention and the awareness of the operators about their safety. On the other hand, Serious games turned out as promising tools to train the workers about safe operating procedures that are difficult to implement in a real working environment. © Springer Nature Switzerland AG 2019.

This paper presents the recent progress in the pre-conceptual design activities for the EU-DEMO divertor Cassette Body, performed in the framework of the work package “Divertor” of the EUROfusion Power Plant Physics & Technology (PPPT) program. According to Systems Engineering Principles, the divertor CAD model is reviewed, considering the updates in the DEMO configuration model presented by the Programme Management Unit (PMU) in 2017. The design parameters affected by these changes and their impact on the divertor design and on the interfaced systems are analysed. Then, the paper focuses on the integration on the new cassette geometry of the divertor sub-systems. This includes the design of a “shielding liner” for cassette body and Vacuum Vessel protection, as well as the development of the cassette body-to-Vacuum Vessel fixation system. The design activities related to these main sub-systems are discussed in detail, in terms of CAD model and thermo-mechanical calculations.
