All alarms or actions before this point should prevent the equipment from reaching the Tech Spec Limit. The plant licensing basis.

• A. Tech Spec Limit
• B. Design/ Test Limit
• C. Break point
• D. Surveillance Requirements

Answer: (A)

The main idea is that the licensing basis defines a fixed boundary value called the Tech Spec Limit, which sets the maximum allowable condition for a parameter. All alarms and automatic actions are designed to keep the plant operating safely by preventing that parameter from reaching or exceeding that limit. In other words, the Tech Spec Limit is the regulatory ceiling you must stay below, and the system of alarms, interlocks, and safe‑shutdown actions is built to ensure you never cross it.

Other concepts mentioned aren’t the licensing boundary itself. Design/Test Limits are internal engineering constraints used during design and testing, not the official regulatory limit the license requires you to stay under. Break point isn’t a standard term for this context. Surveillance Requirements are the ongoing checks to verify you remain within limits, but they describe how you verify compliance rather than define the limit itself.
