Criticality Slide Rule

About the Nuclear Criticality Slide Rule Project

AWE (UK), IRSN (France), LLNL (USA) and ORNL (USA) began a long-term collaboration effort in 2015 to update the Nuclear Criticality Slide Rule for emergency response to a nuclear criticality accident to modernize and expand the technical content of the previous (1998 version) last updated by ORNL.

The detailed plans and accomplishments of the project are provided in the task specifications and summary papers provided below. For additional information on this project, please contact the project coordinator, Johann Herth (IRSN) at johann.herth [at] irsn.fr (johann[dot]herth[at]irsn[dot]fr).
