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.

Radioactive waste management programs worldwide are becoming increasingly comprehensive culminating in a final disposal of the radioactive waste. The maturation of various of the activities leading to such radioactive waste management allows nowadays to address the questions on how to optimize the overall process towards a performant radioactive waste management. Pre-disposal management is hereby key given that it encompasses not only a long time-span between generation of the materials that may become, later-on, totally or partly declared as radioactive waste as well as presenting multiple synergies between various materials/waste process. It is also increasingly allowing for optimization in view of multiple criteria as there are environmental, technical, safety/security/safeguards, regulatory, socio-political, and economic. This panel session will present key elements for such holistic pre-disposal management as essential and strategic domain to optimize the sustainability performance of nuclear energy. These elements will be addressed by three international experts on these matters, i.e.: • Rebecca Tadesse (OECD-NEA) • Anders Sjöland (SKB, Sweden) • Cécile Evans (ORANO, France) Luc Van Den Durpel (Nuclear-21) will moderate this panel-session with Christian Leggett co-chairing.
