1. 1 NRC Perspective on NGA-East Project NGA-East Stakeholder Workshop Dr. Annie Kammerer, P.E.

2. 2 NRC Needs Increased accuracy of PSHA in CEUS Properly capturing and understanding uncertainty –Separating and capturing aleatory variability and epistemic uncertainty Increased buy-in from seismic community Improved regulatory stability

3. 3 Project Motivation Ground Motion Prediction Equations (GMPSs) are generally the single largest source of uncertainty in seismic hazard evaluations NGA (west) project reduced discrepancies between relationships

4. 4 Project Motivation Clear benefits to framework used in NGA –Common and transparent data base and assumptions –Broad buy-in from seismic community The state of ground motion prediction in the CEUS is much less certain than in the WUS –The need for a structured process is even more acute

5. 5 Due to nuclear renaissance, today’s NRC is highly product, schedule, and budget oriented Several additional NRC research projects need results from NGA-East as input Critical that project remains on time and on budget NRC Constraints

6. 6 Motivation for Development Project To develop scope, schedule and cost –Provide NRC understanding of program resource needs and outcomes –Facilitate participation by others Collect and incorporate stakeholder input to develop broad-based support for ultimate product Develop cooperative management and funding agreements with other stakeholders

7. 7 Keys for Success Strive to define critical technical issues and research needs early Establish priorities and develop technical framework Ensure that appropriate researchers are included Develop cooperative managerial framework with other stakeholders Develop realistic schedule and budget No expectation of pro-bono work

8. 8 Summary Improved ground motion prediction equations needed for CEUS NGA program provided framework with high probability of success Initiated development program to define scope, schedule and cost of NGA-East Develop cooperative funding arrangement with stakeholder agencies
