Dynamic PRA Study Michelle M. Gonzalez U.S. Nuclear Regulatory Commission Office of Nuclear Regulatory Research Division of Risk Analysis

Background===
- Dynamic PRA (DPRA) refers to probabilistic risk assessment (PRA) approaches that simulate system behavior and accident scenario development over time.
- DPRA has the potential to provide additional useful risk insights for operating plant design and operations.

Background (cont.)
- DPRA plays a major role in many university PRA research and development programs, and the U.S. Department of Energy is supporting significant national laboratory work.
- The NRC supported early DPRA efforts.
- The NRC is developing staff capabilities to prepare for a changing environment.
Dynamic PRA Study Objectives
- Prepare NRC staff for the efficient use of DPRA tools.
- Prepare NRC staff for future uses of PRAs developed using DPRA methods.
Scope
- Staff development (training)
- DPRA applications: development of simple models of dynamic processes for use in traditional PRA models Expected Outcome
- Better prepare staff to (1) oversee, develop, or review DPRAs in support of future licensing activities and (2) maintain awareness of a still-developing, cutting-edge PRA technology.
Dynamic PRA Study Approach
- Leverage available resources in DPRAThe staff will initially complete a literature review to leverage ongoing DPRA activities to identify methods, approaches, and available DPRA tools.
- Conduct staff development (training)The staff will participate in training exercises to develop capabilities to use the existing DPRA tools.
- Develop simple models using available toolsThe staff will develop hands-on modeling experience by using DPRA tools to develop a simple DPRA model.
Deliverables
- Interim report documenting literature review and DPRA activities
- Staff training on the use of DPRA tools
- Final report documenting DPRA model results
