• 2026-10-13: ANS reported long-running research into Chernobyl's radioactive "hot particles," 40+ years after the Unit 4 meltdown: a Leibniz University Hannover / Helmholtz-Zentrum Dresden-Rossendorf team's paper in the March 2026 Journal of Hazardous Materials (disseminated widely the prior week) examined the fuel components of six hot particles, with findings framed as stable fuel particles and solid-waste disposal progress (ANS). Debut thread on the newgen record — opened as a standalone research item rather than an extension of any existing storyline. Watch for further decommissioning/waste-disposal coverage out of the site that turns this one-off into a trackable thread.
