Working under the mandate of the CSNI, the objective of the WGFCS is to advance the understanding for regulators, technical support organisations (TSOs) and operators of relevant aspects of nuclear fuel cycle safety in NEA member countries. The objective of this workshop is to exchange information and discuss the process and safety improvements in fuel cycle facilities that have taken place in member countries after 2010, particularly after the Fukushima event in 2011. The workshop will recognise earlier work that the WGFCS has done on a specific level since 2010, refreshing it with developed experience of post-Fukushima changes, recent experience of the pandemic and from new members of the WGFCS. It will draw together all of the experience in a single place and add to these the additional effect of advances in fuels on fuel cycle facilities. The outcome will be a document compiling the workshop information that would potentially lead to further work the WGFCS would provide on the development of additional good practice and guidance over existing material. This is particularly useful for new member countries.
