Very excited that you're doing this. The reading and listening list looks terrific. Here are a few suggestions, which you can take or leave! 

Some perspectives from sociology and related fields:

• Tacit Knowledge, Weapons Design, and the Uninvention of Nuclear Weapons. Donald MacKenzie and Graham Spinardi, 1995. (This is essential reading IMO. Extremely well-written, and a perspective I hadn't read anywhere else. I think about it a lot.)
• From 'Inherently Safe' to 'Proliferation Resistant': New Perspectives on Reactor Designs. Sonja D. Schmid, 2021.
• Reimagining Nuclear Engineering. Aditi Verma and Denia Djokic, 2021.
• From Accountants to Detectives: How Nuclear Safeguards Inspectors Make Knowledge at the IAEA. Anna Weichselbraun, 2020.

And a moving piece from the New Yorker (accounts from Hiroshima survivors), and Eisenhower's speech he gave to the UN General Assembly:

• Hiroshima. John Hersey. New Yorker, 1946.
• Eisenhower's "Atoms for Peace" speech. 1953. (Recording.)
