Foreword & Chapter 1 provide a proper entry to the document and to explain its purpose and scope more fully ILW may be roughly categorized into two main groups. One group of ILW contains a relatively high activity, but a low content of long lived radionuclides whereas the other group has a relatively high content of long lived radionuclides, but with low to moderate activity. The volume of ILW is usually more significant than HLW while the activity concentration is more significant than LLW. This justifies the treatment of ILW as a separate waste stream(s). Propose to delete this paragraph (Canada)  use this idea in other sections co-location is important for the context of the safety case. For example, if ILW is co- located with LLW, the characteristics of the ILW will probably dominate whereas if ILW is co-located with HLW, the characteristics of both ILW and HLW need to be considered … this point should be described in other chapters.

Chapter 2 Clarify definitions of ILW. Add explanation why we consider characteristics that is not included in the definition of ILW. (Work on in relation to Chapter 2)

Chapter Consider rewording “It is important to note that the safety concept needs to define and understand the roles and functions of individual barriers and how they interact. They safety case needs to consider the integrated effects of the system, not the each barrier individually. Wording might be updated as necessary (based on Canadian comment 4) 3.4 refer to SSG-29 and improve sentences 3.5 consider referring (rephrasing) SSR-5 requirements 3.5 discuss first sentence 3.6 Justification should be added to clarify why is “particularly important” to have information the radionuclides included in the bulleted list.

Chapter Check if additional description (justification for bullet points) are good enough. 4.5 develop new paragraph on Wigner energy 4.1 Think about comment from UK on hot spot 4.2 consider reference to “current…..” comments from UK 4.6 consider comment from UK 4.6 consider where to move the last sentence to Chapter 5

Chapter 5 Develop new 5.1 on waste characterisation Revise 5.5 on WAC

Chapter check description in other document and revise this part at WG sessions. Combine and Work on in relation to Chapter 2(or 3) Check if we already addressed interactions between co- located wastes in somewhere else, or needs to add example here. If it is already addressed in somewhere, add reference to the section. If not, add example here, or may need to develop a new section resolve comments

Chapter 7 Revise the text to be more ILW-specific

Chapter 8 shorten 8.1 to keep only main ideas for general remarks, revise to be ILW specific Revise 8. Resolve comments in and : add specific description

Chapter 9 Resolve comments from UK/Canada before plenary Discuss about necessity / how to improve this section

Chapter 10 Resolve comments from UK/Canada before plenary Discuss about necessity / how to improve this section

Appendices To be discussed later
