The United States Nuclear Regulatory Commission (US-NRC) is pleased to host the 3rd International Seminar on Probabilistic Methodologies for Nuclear Applications (ISPMNA) on October 22-24,2019, in Rockville, MD.


Since 2013, the Seminar offers a platform for the nuclear industry and regulators to exchange and discuss on the use of probabilistic methods to enhance and complement traditional deterministic regulatory approaches, with the goal of developing more realistic and less overly conservative methodologies.

The presentations will cover state-of-the-art developments of probabilistic methodologies in nuclear industry applications.

Around 30 presentations and two open panel discussions will be scheduled over the course of three days. The topics of discussions include (but are not limited to):

  • Probabilistic Fracture Mechanics (PFM)
  • Probabilistic Fracture Protection
  • Probabilistic Leak Before Break (LBB)
  • Uncertainty and Sensitivity Analysis
  • Development of Input Parameter Distributions
  • Risk-Informed Assessments
  • Development of probabilistic modelling software

The different topics will be discussed in the context of applications in the nuclear industry.  The industry perspective,regulatory context, and the academic quality and feasibility of the proposed methods will be discussed.


As for the previous seminars, there is no registration fee.
