Assessment of Artificial Acceleration Time History Guidance in Standard Review Plan Section 3.7.1, Seismic Design Parameters

This research information letter (RIL) documents the results of research conducted by the U.S. Nuclear Regulatory Commissions Office of Nuclear Regulatory Research (RES) to address technical issues that the program offices experienced when using the guidance in NUREG-0800, Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants: LWR Edition (SRP), Section 3.7.1, Seismic Design Parameters, Acceptance Criterion II.1.B, Design Time Histories. The staff uses this guidance during its review of licensing applications that involve time history analyses of safety-related structures, systems, and components (SSCs) or equipment qualifications using shaking table tests.
