Welcome to  PSA 2021!

Paper Submission Deadline extended to April 15th

Planning Committee Notes

PSA21 planning has spanned across the COVID-19 pandemic. Prior to state closures associated with Pandemic control measures,  we had completed our contract with the Hilton Columbus Downtown.  Due to the rapidly changing conditions over the past year, we have focused attentions on the technical aspects of the meeting.  We believe the conditions will permit us to conduct this meeting safely in person, but please be patient as we update this site with final confirmation.  The committee is focused on finalizing plans for the venue and will aim to open registration soon.  March is a key month for our decision making and confirmation of venue plans.  Please contact John Greenwood with any questions.

We had a great response to our call for papers and look forward to seeing everyone soon!


Since 1978, the ANS biennial international conference on Probabilistic Safety Assessment and Analysis has been a forum for communication of major probabilistic risk and safety topics worldwide, including issues, methods, applications, insights, policy, research, and risk-informed regulation experience.
