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.
Cue Diagnosis Action TD TA Simple Dynamic Model for Operator Action
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
