Nrc Perspective On Nga East Project Priority in all nrc activities • review of “sigma” related topics early in the nga east project to identify necessary research • review of technical issues comprehensively – identifying areas were uncertainties can be reduced through targeted research – identifying areas of epistemic uncertainties that may be under assessed. This “roadmap” summarizes the planning for a major multidisciplinary research program to. develop next generation attenuation models for central & eastern north america (cena), nga east. the nga east is a follow up of a successful multi institution, multi investigator, multi sponsor collaborative project called the next generation.
Nrc Perspective On Nga East Project Nga East Stakeholder Workshop Nrc perspective on nga east project nga east stakeholder workshop dr. annie kammerer, p.e. 1 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 2 project motivation • ground motion. The nga east project objectives were to provide the best estimate of the distribution (median and standard deviation) of horizontal ground motions for the peak ground acceleration (pga), peak ground velocity (pgv), and 5% damped pseudo acceleration response spectra (psa) for oscillator periods ranging from 0.01 to 10 s, on “hard rock” sites. The nga east project went through a comprehensive seismic senior hazard analysis committee (sshac) level 3 peer review process before its release. references abrahamson na, silva wj, kamai r (2014) summary of the ask14 ground motion relation for active crustal regions. The report “nrc staff evaluation of the next generation attenuation for central and eastern north america project (nga east) ground motion model characterization” is a research information letter (ril) issued by nrc's office of nuclear regulatory research to the nrc regulatory and regional offices. ril documents typically summarize.

The project was tasked with developing a new ground motion characterization (gmc) model for cena. the final nga east gmc model includes a set of 17 median ground motion models (gmms) for peak ground acceleration and velocity (pga, pgv) and response spectral ordinates for periods ranging from 0.01 to 10 s.
