What’s the most difficult question you’ve been asked as a maintenance instructor?
Blye Widmar
"Where are the prints?!"
This was the final question in an onslaught of verbal feedback, comments, and critiques I received from my students back in 2019. I had two years of instructor experience and was teaching a class that had been meticulously rehearsed in preparation for an accreditation visit. I knew the training material well and transferred that knowledge effectively enough for all the students to pass the class. As we wrapped up, I asked the students how they felt about my first big system-level class, and they did not hold back.
“Why was the exam from memory when we don’t work from memory in the plant?” “Why didn’t we refer to the vendor documents?” “Why didn’t we practice more on the mock-up?” And so on.

In parallel to the ITER program, the Broader Approach (BA) activities with three projects are being implemented by the European Union (EU) and Japan. Five research and development (R&D) tasks, mainly on blanket-related materials, are being carried out as the DEMO R&D program in the BA to establish key technologies required for the DEMO engineering design. The DEMO R&D building was constructed in March 2010, and the installation of research equipment was completed in March 2011. As the BA DEMO R&D, fabrication technology and/or characterization of reduced activation ferritic/martensitic steels, SiC/SiC composites, and the advanced neutron multiplier and advanced tritium breeder have progressed in Japan and the EU. In the International Fusion Materials Irradiation Facility (IFMIF)/Engineering Design and Engineering Validation Activities (EVEDA) project, engineering design and validations have progressed. The injector of the IFMIF prototype accelerator produced first beam successfully in May 2011 and will be delivered to the Rokkasho BA site in 2012. The commissioning of the EVEDA lithium test loop was completed in March 2011, and a lithium flow of 25 mm thick at [approximately]5 m/s was obtained.
