Outline
- Background
- The evolution of NRCs Standard Review Plan (SRP) on seismic input motion acceptance criteria
- A cursory account of the history of RS and PSD in SMC/SIMD
- One way to meet both PSD and RS criteria
- Introduction of the NRC/NEA SIMD Workshop in May 2026 Goal Seek a shared reflection of the century-long evolution of response spectra (RS) and power spectral density (PSD) in seismic motion characterization (SMC) and seismic input motion development (SIMD) 10/29/2024 2
Background:
RS Matching Criteria Alone are Not Adequate RS/ISRS Frequency (Hz)
Spectral Acceleration (g)
ZPA: Zero Period Acceleration ISRS: In-Structure Response Spectra RS ZPA on ISRS 3
10/29/2024
RS ZPA on ISRS in 3D Fo ISRS value at the oscillator frequency Peak ISRS 10/29/2024 4
Very Similar RS but Vastly Different ISRS (5 Hz - 15 Hz) 10/29/2024 5
Comparison of PSD from 5 Hz to 15 Hz 6
T2 - Broadband T3 - Broadband with 5-15 Hz Cut The red solid curve is the smoothed PSD The dotted curve is the raw PSD The solid piecewise linear curve is the target PSD The dashed piecewise linear curve is 80% of the target PSD 10/29/2024

The May 2026 NRC/NEA Workshop Seismic Input Motion Development (SIMD) for Analysis and Design of Nuclear Installations Objectives
- 1) Share the current state of practice in SIMD among member states,
- 2) Raise awareness of the necessity for PSD checks,
- 3) Achieve consensus for integration of RS matching and PSD checks, and
- 4) Explore future activities to completement RS with PSD or other good practices for seismic hazard analysis, seismic load specification, seismic analysis and design, and seismic risk assessment.
Welcome all to join the workshop!!!
10 A convergence of (1) the evolution of the SRP and (2) the decades-long recognition that PGA and RS are incomplete indicators of the damaging capacity of seismic motions.
