"Satellite Imagery Analysis-Current State of the Zaporizhzhia Nuclear Power Plant and Concerns Going Forward"

SPF China Observer

Organized by: Sasakawa Peace Foundation
The Sasakawa Peace Foundation has been conducting a project to publish research papers to analyze China's politics, economy, society, diplomacy, and security by Japanese experts through a satellite website, SPF China Observer. In addition, public forums are periodically held with the authors of this project.

In this fourth session of the FY2022 program, using satellite imagery, we will analyze the current situation at the Zaporizhzhia nuclear power plant and discuss potential concerns. The situation has become increasingly tense with the shelling of the plant, which is the largest nuclear power plant in Europe occupied by Russia, with discussions also continuing on the possibility of using a large-scale release of radioactive materials resulting from reactor damage as a so-called “nuclear shield.” In this session, the speaker will be Mr. Yuki Kobayashi (Research Fellow, Sasakawa Peace Foundation), the author of the article "Current State of the Zaporizhzhia Nuclear Power Plant and Concerns Going Forward” (available at the link below) and the discussant will be Mr. Yu Koizumi (Lecturer, Research Center for Advanced Science and Technology, The University of Tokyo). Additionally, Mr. Bonji Ohara (Senior Fellow, Sasakawa Peace Foundation), will moderate the discussion.

We look forward to your participation.
