How does NANTeL ensure proper seismically qualified operation?

• A. Seismic qualification of components, robust mounting, design margins, and testing to validate performance after seismic events.
• B. Keeping equipment away from the ground.
• C. Using only electronic components that are rated for high temperature.
• D. Performing no testing after earthquakes.

Answer: (A)

Seismically qualified operation means the system is proven to function through a design earthquake and remain reliable afterward. This is achieved by four coordinated elements: components are qualified to withstand seismic loads, equipment is mounted robustly so it won’t loosen or detach during shaking, design margins provide safety against uncertainties and aging, and testing after seismic events verifies that performance and safety functions are still met. For NANTeL, these parts work together to ensure protection functions remain available when an earthquake occurs and after it settles. Keeping hardware off the ground, relying only on high-temperature ratings, or skipping post-quake testing don’t address the essential mechanical reliability, or the need to verify continued operation after shaking, so they don’t fit the goal of proper seismically qualified operation.
