Proliferation Resistance and Physical Protection Gen IV Nuclear Systems Crosscutting Topics - 2022

There are several topics related to PR&PP which crosscut the various system white papers. To avoid redundancy in each individual white paper, discussion on these topics is presented in this companion document from a technology-inclusive perspective but with a focus on their impact on PR&PP. Crosscutting topics may either be common to all the various system designs or crosscutting with similar themes across all system designs. This paper updates and widens the topics covered in the crosscut section of the 2011 report including the six systems white papers. New topics, including Small Modular and Microreactor Options, Life Cycle, Flexibility, and Cyber Threat have been added. This document, prepared by the GIF PRPPWG, follows the high-level paradigm of the GIF PR&PP Evaluation Methodology to investigate the key points of PR&PP features crosscutting the various designs. The high-level conclusions from the twelve areas considered are presented at the end of the paper.
