Seismic qualification requirements for nuclear power plant safety-related equipment per IEEE 344-2013, NRC Regulatory Guide 1.100 Rev.4, and NRC RG 1.60/1.61. Covers equipment seismic categories (Class 1E, Category I/II, non-seismic), test levels (OBE/SSE in g), Required Response Spectra (RRS) frequency ranges, damping ratios, fragility parameters (median capacity Am, randomness beta_R, uncertainty beta_U, HCLPF) by equipment class (switchgear, MCC, I&C panels, diesel generators, pumps, valves, piping, tanks), and anchorage design requirements.
