PRA aims to identify plant vulnerabilities after analyzing severe accident behavior. Which of the following best restates this goal?

• A. To identify vulnerabilities
• B. To maximize production
• C. To measure worker productivity
• D. To estimate safety margins in operation

Answer: (A)

Probabilistic Risk Assessment aims to uncover weaknesses in the plant by studying how severe accidents could unfold and where failures or design gaps could lead to significant risk. That focus makes the best restatement identifying vulnerabilities. Options about maximizing production or measuring worker productivity miss the purpose of risk analysis, and while PRA results can inform safety margins, the primary objective is to reveal vulnerabilities to guide mitigation and improvement.
